Saturated Shores in Southeastern Texas

There is almost no trace of the human, or of the extreme overurbanization of the Texas coast, in most of the maps that were created of the extreme flooding and intense winter rains that hit Galveston and Houston TX with the windfall of Hurricane Harvey.  While maps serve to orient humans to the world–and orient us to human processes and events in a “human world,” as J.B. Harley and David Woodward put it, the confused nature of relations between the human and natural world, is increasingly in danger of being mipmapped.  Data visualizations of extreme weather that erase the modification of coastal environments provide a particularly challenging means of orientation, as news maps are suspended between registering the shock of actual events–and trying to contain the natural emergencies that events of extreme weather create–and the demand for graphics that register natural calamities and the ethics of showing such calamities as “natural”–or even what the category of the natural is in coastal regions that so heavily modified to modify actual weather events.

The ethics of orienting viewers to the rainfall levels that fell in Houston after the landfall Hurricane Harvey Part of the huge difficulties lies in adequately orienting viewers in ways that register a changing natural world–how we are mapping rainfall, for example, or the approach of hurricanes, or are rather mapping the new relation of rain to built surfaces and landcover change that lack permeability for water, facilitating flooding by storms whose potency is changed by the greater atmospheric content of a warming Gulf of Mexico, which the ground cover of Houston, Galveston, and the Texas shore are less able to absorb and return to the Gulf. The area is, itself, something of an epicenter of the increased number of hemispheric tropical cyclones–which demand warm water temperatures above 80 80°F / 27°C and a cooling atmosphere and low wind shear–often led to the Gulf coast.

–the intersection between cyclones and areas of paved ground cover is problematic to the southwestern states, and most of all to Texas, Louisiana, and Florida, where water absorption has been anthropogenically reduced in recent decades. At the same time, few other areas of the inhabited world are so widely “tracked” as the destination of tropical cyclone formation..

The problem is partly evident in the choice of new color ramps that transcend the rainbow spectrum of measuring the intensity of rainfall in the recent arrival or ground fall of Hurricane Harvey, which condenses the great difficulty of using old cartographical categories and conventions in order to capture or communicate increasingly extreme weather conditions. in an era of climate change.  But the cartographic problem goes farther:  for it lies in the difficulty of registering the changes in relations f how rain dropped meets the ground, mapping relations between complex processes of warming and atmospheric warmth that lead to greater humidity across the gulf region to ground cover permeability that leaves regions increasingly exposed to flooding.

The relentless logic of data visualizations based on and deriving primarily from remote sensing are striking for rendering less of a human world than the threat of allegedly “natural” processes to that world.  Perhaps because of the recent season of extreme weather we have experienced, weather maps may be among the most widely consulted visualizations in our over-mediated world, if they were already widely viewed as the essential forms of orientation.  But the pointillist logic of weather maps may fail to orient us well to extreme events as the hurricane that dumped a huge amount of water on overbuilt areas to include the human–or the human world–seem a tacit denial of the role of humans in the complex phenemona of global warming that have, with the warming waters of the Gulf of Mexico and ever-increasing ozone over much of the overbuilt southeastern Texas shore, created a perfect storm for their arrival.

This failure to include this role haunts the limited content of the weather map; including the role of humans in maps of extreme weather events indeed remains among the most important challenges of weather maps and data visualization, with the human experience of the disasters we still call natural.  And although the subject is daunting, in the spirit of this blog, we will both look at the communicative dilemmas and difficulties of eye-catching color ramps and their deceptiveness, and poetic difficulties of orienting oneself to shores.  For as the disaster of Harvey is depressing, it compels raising questions of the orientation to the shifting shore, around the national epicenter of Galveston, where the landfall of Hurricane Harvey focussed our attention on August 27, 2017–

–and the meaning of place in an saturated shoreline, where the sea is somehow part of the land, and the land-sea divide blurs with a specificity that seems as if it may well be increasingly true in an approaching era of climate change.  And as we depend on the ready generation of maps based on remote sensing whose relentless logic is based on points, we risk looking sight of the role of place in determining the relations of rainfall to shoreline in maps of coastal flooding that remove remote observations from the built environment that flooding so drastically changes, challenges and affects, in ways that may elide specificities of place.

At a time when we are having and will be destined to have increased problems in orienting ourselves to our shores through digital maps of rainfall, the unclear shorelines of Galveston sent me to the bearings that a poet of an earlier age took her bearings on the mapped shorelines of the place where she had been born, and how she was struck by a bathymetric map to gauge her personal relation to place, and saw place in how the changing shoreline of the northern Atlantic were mapped in the maritimes, in a retrograde form of print mapping in a time of war.  For the way the mapped shore became a means by which Elizabeth Bishop gained bearings on shores through a printed map of coastal bathymetry to access the spatiality of the shore–how “land lies in water” and the blurred relation of land and water that the bathymetric map charts–in an age when the materiality of the map was changing, with the introduction of aerial composite maps from the early 1930s, as the rise of aerial composite maps removed the hand of the mapmaker from the map in an early instance of remote sensing–

Cartography Associates/David Ramsey: Historical Map Collection: Composite of 164 Aerial Views of San Francisco by Harrison Ryker/Oakland, 1938, 1:2000

–in a medium of aerial photography that focussed on land to the exclusion of water, and that all but erased the relation between water and shore just a few years after Bishop quickly wrote her poem in Christmas 1935 about coastal “edges” of land and sea.  Ryker, who developed techniques of aerial photography used in the mapping of the shores of Puerto Rico for the Fairchild Aerial Camera Company, as well as photographs of the devastating Berkeley Fire of 1923, went into business in 1938–the year of his map–as a map publisher, with a patent for the stereoscope used to interpret aerial imagery,  and must have performed the massively detailed mapping of San Francisco in one hundred and sixty for images taken from airplanes from 1937-38 as a sort of calling card, soon after Bishop wrote her poem, before manufacturing a range of stereoscopes of pocket and desktop versions for military ends that were widely used in World War II by the US Army.

Before war broke out, but in ways that anticipated the coming war, the printed bathymetric map must have resonated as a new reflection on the impersonality of the aerial view; Bishop was suddenly struck when she encountered the materiality of a print map on Christmas 1938 as the art of cartography was already changing, responding to the drawn map under glass of the Atlantic as a way to recuperate the personal impact of place.  Her poem powerfully examined the logic of drawn maps utterly absent from the digitized space of rainfall maps of a flood plain, deriving from data at the cost of human inhabitation of place–and in envisioning data to come to terms with the catastrophic event of flooding distancing or removing the craft of mapmaking from the observer in dangerously deceptive ways.  And so after wrestling with the problems of cartographic representation using remote sensing, while recognizing the value of these readily produced maps of rainfall and the disasters they create,

1.  For weather maps are also among the most misleading points to orient oneself to global warming and climate change, as they privilege the individual moment, removed from a broader context of long-term change or the human alteration of landscape.  They provide endless fascination by synthesizing an encapsulated view of weather conditions, but also  suggest a confounding form of media to orient audiences to long-term change or to the cascading relations of the complex phenomenon of climate change and our relation to the environment, as they privilege a moment in isolation from any broader context, and a sense of nature removed from either landscape modification or human intervention in the environment, in an area were atmospheric warming has shifted sea-surface temperatures.  The effects on the coast is presented in data visualizations that trace the hurricane’s “impact” as if its arrival were quite isolated from external events, and from the effects of human habitations on the coast.  The image of extreme flooding is recorded as a layer atop a map, removing the catastrophic effects of the flooding from the overpaved land of the megacities of southeastern Texas, and the rapid paving over of local landcover of its shores.

.

Such visualizations preserve a clear line between land and sea, but treat the arrival of the rains on land as isolated from the Consuming such events of global warming in color-spectrum maps.  The data of rainfall translate data into somewhat goofy designs represents a deep alienation from the environment, distancing viewers in dangerous ways from the very complexity of global warming that Gulf coast states encountered.

Such data visualizations seem dangerously removed notion of how we have changed our own environment, by describing a notion of “nature” that is immediately legible, as if it were removed from any human trace or of the impact of modification of the land, and by imaging events in isolation from one another–often showing a background in terrain view as if it has no relation to the events that the map describes.  Although weather maps and AccuWeather forecasts are sources of continual fascination, and indeed orientation, they are are also among the most confounding media to orient viewers to the world’s rapidly changing climate–and perhaps among the most compromised.  For they imply a remove of the viewer from space-and from the man-made nature of the environment or the effects of human activity form the weather systems whose changes we increasingly register.  By reifying weather data as a record of an actuality removed from human presence at one place in time, they present a status quo which it is necessary to try to peel off layers, and excavate a deeper dynamic, and indeed excavate the effects of human presence in the landscape or geography that is shown in the map.  We are drawn to tracking and interpret visualizations of data from satellite feeds in such weather maps–or by what is known as “remote sensing,” placed at an increased remove from the human habitation of a region, and indeed in a dangerously disembodied manner.

Visualizations resulting from remote observation demand taken as a starting point to be related to from the human remaking of a region’s landscape that has often increasingly left many sites increasingly vulnerable to climate change.  But the abstract rendering of their data in isolation from a global picture–or on the ground knowledge of place–may render them quite critically incomplete.  The remove of such maps may even suggest a deep sense of alienation form the environment, so removed is the content of the data visualization form human presence, and perhaps from any sense of the ability to change weather-related events, or perceive the devastating nature of their effects on human inhabitants:   their stories are about weather, removed form human lives, as they create realities that gain their own identity in images, separate from a man-made world, at a time when weather increasingly intersects with and is changed by human presence.  While throwing into relief the areas hit by flooding near to the southeastern Texas shore at multiple scales based on highly accurate geospatial data, much of which is able to be put to useful humanitarian uses–

–the reduction of floods to data points creates a distorted image of space renders their occurrence distant from the perspective of folks on the ground, and places their content at a considerable remove from the complex causality of a warming Gulf of Mexico, or the problems of flood drainage by which Galveston and Houston were beset.  Indeed, the multiple images of that report rainfall as an overlay in a rainbow spectrum, at a remove from the reasons for Houston’s vulnerability to flooding and the limits the region faces of flood control, in broadcast Accuweather images of total rainfall in inches advance a metric that conceals the cognitive remove from the dangers of flooding, ora human relation to the landscape that the hurricane so catastrophically affected.  Can we peel under the layers of the data visualization, and create better images that appreciate the human level on which the landscape stands to be devastated by hurricane rains, as much as tracking the intensity of the growth of rainfall over time?

Such layers of green, meant to suggest the intensity of rainfall that fell over land, reveal the concentration of water in areas closes to the Gulf of Mexico.  Even the most precise geographical records of the dangers of flooding in the floodplain of southeastern Texas with little reference to the historical modification of the region by inhabitants–

–and conceal the extent to which the landscape’s limited ground cover permeability has left the region far more susceptible to flooding, and elevated the risks of the emergency.  The problem of reading any signs of human presence into these “images” of precipitation provoke problems of disentangling remote sensing data from knowledge of the region’s recent urban growth and the consequent shift in local landcover.

The perspective of our relation to these events is often as fleeting and as existential as they flood us with data, which we viewers have little perspective or tools to process fully.  The onrush of recent remote sensing maps batter us with an array of data, so much as to lead many to throw up their hands at their coherence.  Even as we are  still trying to calculate the intensity of damages in Puerto Rico–where electricity is so slowly returning that even even after four months, almost a third of its 1.5 million electricity customers still lack power–and the cost of fires in southern California.  We look at maps, hoping to piece together evidence of extensive collateral damage of global warming.  Yet we’ve still to come to terms with the intensity of rainstorms that hit southeastern Texas–deluging the coast with rainfall surpassing the standard meteorological chromatic scale that so misleadingly seems to offer a transparent record of the catastrophe, but omits and masks the experiences of people on the ground, digesting swaths of remotely sensed data that take the place of their perception and experience, and offering little critical perspective on the hurricane’s origin.

The rapidity with which rain challenged ground cover permeability provides both a challenge for mapping as a symptom of global warming and landscape modification:   the mapping of “natural” levels of rainfall blurs the pressing problem of how shifting landcover has created an impermeability to heightened rains, and indeed how the new patterns of habitation challenge the ability of the coast of the Gulf of Mexico to absorb the prospect of increased rain in the face of decreasing groundcover permeability, and the extreme modification of the coastline that increasingly impeded run-off to the Gulf.

2.  Across much of southeastern Texas, a region whose growth was fed by the hopes of employment in extractive industries, real estate demand and over-paving have unfortunately intersected with extreme weather in southeastern Texas in ways which dat visualizations have had trouble exposing, but which raise a curtain on the coming crises of a failure of ability to accommodate increased levels of rainfall  If the lack of precedent for the intense rainfall in Galveston Bay generated debate about introducing a new color that went beyond the rainbow scale employed in weather charts, what seemed a problem of the cartographic color-spectrum suggested a problem of governability and indeed government response to extreme weather conditions.  How to register the dangers of rainfall that goes of the scale or standards of measurement?

One must consider how to orient viewers to the intensity of consequent flooding, and to its consequences and better prepare ourselves for the arrival of deluging rains without falling back on the over-freighted metaphor of rains of biblical scope.  How many more hurricanes of increasing intensity can continue to pound the shores, by whipping precipitation from increasingly warming waters and humid air?  The cumulative pounding of tropical cyclones in the Gulf stands to create a significantly larger proportion of lands lying underwater–temporarily submerged lands–with radically reduced possibilities of drainage, as hurricanes carry increased amounts of evaporated water from the humid air of the warming gulf across its increasingly overbuilt shores. in ways that have changed how the many tropical cyclones that have crossed the land-sea threshold since NOAA began tracking their transit (in 1851) poses a new threat to the southeastern coast of Texas, and will force us to map the shifting relation between land and water not only in terms of the arrival of hurricanes, or cyclonic storms–

–but the ability of an increasingly overbuilt landscape to lie underwater as the quantity of the Gulf coast rainfall stands to grow, overwhelming the overbuilt nature of the coast.

Most maps that chart the arrival and impact of hurricanes seem a form of climate denial, as much as they account for climate change, locating the hurricanes as aggressive forces outside the climate, against a said backdrop of blue seas, as if they  are the disconnect.  Months after the hurricane season ended, the damage for hurricanes caused have hardly been assessed in what has been one of the most costly and greatest storm damage since 1980 in the United States,–including the year of Hurricane Katrina–we have only begun to sense the damage of extreme weather stands to bring to the national infrastructure.  The comparison to the costs of storm damage in previous years were not even close.

But distracted by the immediacy of data visualizations, and impressed by the urgency of the immediate, we risk being increasingly unable to synthesize the broader patterns of increased sea surface temperatures and hurricane generations, or the relations between extremely destructive weather events, overwhelmed by the excessive destruction of each, and distracted from raising questions about the extremely poor preparation of most overbuilt regions for their arrival, and indeed the extent to which regional over-building that did not take the possibility of extreme weather into account–paving large areas without adequate drainage structures or any areas of arable land–left inhabitants more vulnerable to intense rains.  For in expanding the image of the city without bounds, elasticity, or margins for sea-level rise, the increasingly brittle cityscapes of Galveston and much of the southeastern Texas shoreline were left incredibly unprepared for the arrival of hurricanes or intense rains.  Despite the buzz of an increased density of hurricanes to have hit the region,

1851_2013_mjrhurr2

the questions of how to absorb hurricanes of the future, and to absorb the increased probability of rainfall from hurricanes in the Gulf of Mexico and its shores, suggests questions of risk, danger, and preparation that we have no ability to map.  What, indeed, occurs, as hurricanes themselves destroy the very means of transmitting on the ground information and sensing weather, and we rely exclusively on remote sensing?

To characterize or bracket these phenomena as “natural” is, of course, to overlook complex interaction between extreme weather patterns and our increasingly overbuilt environments that have both transformed the nature of the Southeastern Texas coast and have made the region both an area of huge economic growth over time, and have paved over much of the floodplain–as well as elevated the potential risks that are associated with coastal flooding in the Gulf Coast.  To be sure, any discussion of the Gulf of Mexico must begin from the increasingly unclear nature of much of our infrastructure across land and sea, evident in the range of pipelines of gas and oil that snake along a once more clearly defined shore charted by ProPublica in 2012, revealed the scope of the manmade environment that has both changed the relation of the coastal communities to the Gulf of Mexico, and has been such a huge spur to ground cover change.

The expansive armature of lines that snake from the region across the nation–

-and whose tangle of oil pipelines that extend from the very site of Galveston to the Louisiana coast is almost unable to be defined as “offshore” save as a fiction, so highly constructed is much of the national waters in submerged lands in the Gulf of Mexico–

They indeed seem something of an extension of the land, and a redefinition of the shore, and reveal a huge investment of the offshore extractive industries that stand to change much of the risk that hurricanes pose to the region, as well as the complex relation of our energy industries to the warming seas.  Yet weather maps, ostensibly made for the public good, rarely reveal the overbuilt nature of these submerged lands or of the Gulf’s waters.

Despite the dangers that such an extensive network of hazardous liquid lines along the Gulf of Mexico, the confusion between mapping a defined line between land and water, and visualizing relations of extreme weather disturbances as hurricanes in the Gulf of Mexico and local infrastructure haunts the extremely thin nature of the sort of data visualizations that are generated about the dangers of hurricanes and their landfall in the region.  For all too often, they presume a stable land/sea divide, removed from the experience of inhabitants of the region and how we have remade the shore.

3.  How can we better integrate both a human perspective on weather changes, and the role of human-caused conditions in maps of extreme weather?  How can we do better by going beneath the data visualizations of record-breaking rainfall, to map the human impact of such storms?  How could we do better to chart the infrastructural stresses and the extent to which we are ill-prepared for such extreme weather systems whose impact multiplies because of the increased impermeability of the land, unable to absorb excessive rainfall, and beds of lakes and reservoirs that cannot accommodate increased accumulation of rainfall that  stand to become the new normal?  The current spate of news maps that provoke panic by visualizing the extremes of individual cases may only inspire a sort of data vis-induced ADD, distracting from infrastructural inadequacies to the effects of global warming–and leaving us at a loss to guarantee the best structures of governability and environmental readiness.

Indeed, the absence of accurately mapping the impact and relation between landcover, storm intensity, rainfall, flooding, and drainage abilities increases the dangers of lack of good governance.  There need not be any need for a reminder of how quickly inadequate mapping of coastal disasters turns into an emblem of bad governance.  There is the danger that, overwhelmed by the existential relation to each storm, we fail to put them together with one another; compelled to follow patterns of extreme weather, we risk being distracted from not only the costs but the human-generated nature of such shifts in seasons between extremes of hot and cold.  For as we focus on each event, we fail to integrate a more persuasive image of how rising temperatures stand to create an ever-shifting relation between water and land.

Provoked by the rhetoric of emergency, we may need to learn to distance ourselves better from the aerial views that synthesize intense precipitation, tally hurricane impacts, or snowfall levels, and view them less as individual “strikes” or events and better orient ourselves to a broader picture which put us in a less existential relation to extreme weather.

We surely need to establish distance to process syntheses of data in staggering aerial views on cloud swirl, intense precipitation, and snowfall, and work to peel back their striking colors and bright shades of rainbow spectra, to force ourselves to focus not only on their human costs, or their costs of human life, but their relation to a warming planet, and the role of extreme of weather in a rapidly changing global climate, as much as track the “direct strikes” of hurricanes of individual names, as if they were marauders of our shores:  their creation is as much tied to the changing nature of our shores and warming sea-surface temperatures, and in trying to create a striking visualization, we deprive ourselves from detecting broader patterns offering better purchase on weather changes.

The Weather Channel

If patterns of weather maps epitomized by Accuweather forecast and projections suggest an exhilaratingly Apollonian view on global and regional weather patterns, they also  shift attention form a broader human perspective in quite deeply pernicious ways.  Such maps provided the only format for grasping the impact of what happened as the hurricane made landfall, but provided little sense of the scale of inundations that shifted, blurred and threatened the coast of the Gulf of Mexico.  They provide a format for viewing floods that are disjoined from victims, and seem to naturalize the quite unnatural occurrence of extreme weather systems.  Given the huge interest in grasping the transformation of Hurricane Harvey from a tropical storm to a Category Four hurricane, and the huge impact a spate of Category Four hurricanes have created in the Gulf of Mexico, it’s no surprise that the adequacy of the maps of Hurricane Harvey have been interrogated as hieroglyphs or runes of a huge weather change:  we sift through them for a human story which often left opaque behind bright neon overlays, whose intensity offer only an inkling of a personal perspective of the space or scale of their destruction on the ground:  while data maps provide a snapshot of the intensity of rain-levels or wind strength at specific sites, it is difficult if important to remember that their concentration on sites provide a limited picture of causation or complexity.

All too often, such maps fail to offer an adequately coherent image of disasters and their consequences, and indeed to parse the human contributions to their occurrence.  This post might be defined into multiple subsections.  The first actions suggest the problems of mapping hurricanes in the Gulf of Mexico in relation to flooding in data visualizations of the weather and the overbuilt region; the middle of the post turns to an earlier poetic model for considering the relation between land and sea that visualizations all too easily obscure, and the meaning that the poet Elizabeth Bishop found in viewing relations between land and sea in a printed map of the Atlantic; after returning to the question of the overbuilt shore compounds problems of visualizing the Texas coast, the final section, perhaps its most provocative, returns to Bishop’s reading of a map of the Atlantic coast.

What such new weather maps would look like is a huge concern.  Indeed, as we depend on weather maps to orient us to place ourselves in the inter-relations of climate change, sea-level, surface temperatures, and rain, whether maps cease to orient us to place, but when best constructed help to describe the changing texture of weather patterns in ways that can help familiarize us not only to weather conditions, but needed responses to climate change.  For  three months after the hurricanes of the Gulf of Mexico caused such destruction and panic on the ground, it is striking not only that few funds have arrived to cover costs of rebuilding or insurance claims, but the judgement or understanding of the chances for future flooding have almost left our radar–perhaps pushed rightly aside by the firestorms of northern and southern California, but in ways that troublingly seem to forget to assess or fail to assess the extent of floods and groundwater impermeability  along the Texas and Louisiana coast.  The problems that preparation for future coastal hurricanes off the Gulf of Mexico raise problems of hurricane control and disaster response that seem linked to problems of mapping their arrival–amd framing the response to the increasing rains that are dumped along the entire Gulf Coast.

Indeed, the chromatic foregrounding of place in such rainbow color ramps based on GPS obscure other maps.   Satellite data of rainfall are removed from local conditions, and serve to help erase complex relations between land and water or the experience of flooding on the ground–by suggesting a clear border between land and sea, and indeed mapping the Gulf of Mexico as a surface as if it were unrelated to the increased flooding around Houston, in maps prepared from satellite imagery, despite the uneasy echoes of anthropogenic causes for the arrival of ten hurricanes in ten weeks, in ways that suggest how warming waters contributed to the extreme inundation of the Gulf Coast.  Despite NOAA  predictions of a 45% likelihood of ‘above-normal’ activity for the 2017 Atlantic hurricane season, with, a 70% likelihood of storms that could transform into hurricanes, the images of inundated lands seem both apocalyptic and carefully removed from the anthropogenic changes either to the ocean or land that intensified their occurrence so dramatically on the ground.

Is it possible to recuperate the loss of individual experience in such data maps, or at least acknowledge their limitations as records of the complexity of a changing climate and the consequences of more frequent storm surges and such inundations of rainfall?  As we seek better to understand the disaster relief efforts through real-time maps of effects of Hurricane Harvey as it moved inland from the Gulf of Mexico, shifting from Category 4 Hurricane from a tropical storm, we tried to grasp levels of rainfall that spun out of 115-mile-an-hour winds across southeastern Texas that damaged crops, flooded fields, ruined houses, and submerged cars, we scan stories in hope of clues to assess our position in relation to increasingly dangerous weather systems whose occurrence they may well forebode.  At a time of increased attention to extreme weather has long developed, the gross negligence of climate change denial is increasingly evident:  it recalls the earlier denial of any relation between hurricanes and climate change, when increased hurricanes were cast as “the cycle of nature,” rather than as consequences whose effects have in fact been broadly intensified by human activity.

Current attempts to map the toll of record-smashing hurricanes focused almost exclusively on point-based data view rainstorms largely as land-based records; even as they intend to monitor the effects of Harvey’s landfall by microwave censors, they risk seeming to isolate real-time rainfall levels from the mechanics warmer air and sea-surface temperatures which result from human-caused global warming, not relating increased storm surges or inundations to achanges in coastal environments or climate change.  To render such changes as natural–or only land-based–is irresponsible in an age of reckless levels of climate denial.  Indeed, faced by the proliferation of data visualizations, part of the journalistic difficulty or quandary is to integrate humanistic or individual perspectives on the arrival of storms, rendered in stark colors in the increasingly curtailed ecosystems of newsrooms which seek simplified visualizations of satellite data on the disaster, which fail to note the human contributions to the travails that are often reserved for photographs, which increasingly afford opportunities of disaster tourism in the news, emphasizing the spectator’s position before disasters, by images that underscore the difficulties in processing or interpreting the proliferation of data from MODIS satellite feeds:  we can show the ability to measure the arrival of torrential rains, but in offering few legends, save the date and scale, but offering few keys o interpret the scale of the disaster.

The looming portent of human-made climate change, however, underlies the poor predictions that NOAA offered of perhaps 2-4 major hurricanes this Spring, and the lack of a new director for NOAA–on which local and state agencies depend to monitor the nations shores and fisheries–suggested the, from June to September, which left states on their own to make decisions and plan for disaster mitigation programs and better flood maps.  (The danger of appointing a newly nominated director, Barry Myers, who is a strong supporter of the privitization of weather maps and an executive at the private Accuweather mapping service, suggests the difficulty of determining the public-private divide in an era of neoliberalism, and a free market of weather maps that were once seen as central to national security and standards of safety.)   There are two hidden scales on which we read these opaque maps of global warming and globalization and local inundation are triply frustrating.   For all the precision and data richness of such point-maps of largely land-based rainfall, local temperature, or flooding, the biases of such instantaneous measurements seem to fit our current governing atmosphere of climate change denial, and dangerous in erasing how such storms are informed by long-term consequences of man-made climate change.  (As the mapping tools of coastal weather seem destined to change, what sort of change in direction for NOAA coastal maps do we want:  the appointment suggests the terrifying possibility of a return to the Bush-era proposal nominee Myers supported that prohibiting the agency from producing any maps already available in the private sector then threatened federal weather lines to go dark–lest they literally compete with ad-supported websites private providers–and shift federal information offline?)

For making moves toward the future readability of weather maps may well be at stake in critically important ways.  The 2005 proposal that Myers backed would have eliminated the National Weather Service, even while exempting those forecasts needed to preserve “life and property,” would in essence have returned the weather services to a pre-internet era, even as the most active hurricane season including a record breaking fifteen hurricanes and twenty-eight storms began in the gulf coast, including the infamous hurricane Katrina.  The proposed bill would have prevented NOAA from posting open data, and not only readily available to researchers and policymakers, in ad-free formats, free of popup screens, but allow them to make their own maps on the fly–ending good practices of posting climate data would work quite dangersously to prevent development of tools of data visualization outside commercial models of rendering storms and hurricanes as if environmentally isolated.

A deeper problem of providing such limited weather maps of tropical storms may be the subtexts about the relation of human causes to weather they convey, and the absence of a greater narrative of the transformation of a global ecology or of the ecology of the Gulf Coast.  The curtailed images of “nature” they present by symbolizing rains, winds, floods, or submerged regions in appealing hues as natural–raise questions of the odd simplicity of the absent storylines:  cheery colors erase or bracket complex questions of climate change, the human contribution to extreme weather events, or the human experience of suffering on the ground:  Rita, Cindy, Katrina, Dennis, and Wilma seem not part of the environment, epiphenomenal interlopers moving across a static deep blue sea, in an apparent dumbing down of the mechanics of hurricane or storm formation in a rainbow spectrum removed from a human-made environment.

The Cognitive Clouding of Global Warming: Paris and Pittsburgh; Creditors and Debtors

The argument of America First seems to have been extended to its logical conclusion as the apparently selected President of the United States has single-handedly subtracted the nation from a map of climate change.  By denying the place of the United States in the Paris Climate Accords, President Trump seems, in the most charitable interpretation, to have acted on his own instincts for what was the benefit that accrued to the country in the very short term, and after looking at the balance books of the United States government for what might have been the first time, decided that America had no real part in the map of the future of a warming world.  Rather than outright denying global warming or climate change, Trump decided that the conventions established to contain it by the world’s nations had no immediate advantage for the United States.  

The result wasn’t really to subtract the United States from the ecumene, but from the phenomenon or at least the collective reaction of the world to climate change, and openly declare the supremacy of his own personal opinion–as if by executive fiat–on the matter. The personal position which he advanced was so personal, perhaps, to be presented in terms of his own clouded thinking on the matter, or at least by seizing it to create what he saw as a wedge between national consistencies, and to use wildly incommensurate forms of data to create the impression of his own expertise on the issue–and to mislead the nation.  For Donald Trump took advantage of his having Presidential podium to diss the Paris Accords by a torrent of alliteration developed by a clever speechwriter as resting on a “cornucopia of dystopian, dishonest and discredited data.”  Even if one wants to admire the mesmerizingly deceptive excess of alliteration, the notion of rooting an initial response to planetary climate change in the perspective of one nation–the United States of America–which produced the lion’s share of greenhouse gasses–is only designed to distort.  

By pretending to unmask the Paris Accords as in fact a bum economic deal for the United States, as if it were solely designed to “handicap” one national economy, set a sad standard for the values of public office.  For as Trump dismissed data on climate change as discredited with mock-rage, and vowed that the entire affair had been designed by foreign groups who had already “collectively cost America trillions of dollars through tough trade practices” and were desiring to continue to inflict similar damage.

But the large future on trade imbalances–which he treated as the bottom line–he staged a spectacle of being aggrieved that seemed to take on the problems of the nation, with little sense of what was at stake.  Trump’s televised live speech was preeminently designed only to distract from the data on which the Accords had been based.  And even as Trump sought to pound his chest by describing the Accord as a “bad deal for Americans,” that in truth “to the exclusive benefit of other countries.”  By turning attention to an America First perspective on global warming, Trump sought to replace the international scope of the challenge–and intent of the much-negotiated Climate Accords–by suggesting that it obscured American interests, even if it only took America’s good will for granted.  As if explaining to his televised audience that the agreement only “disadvantages the United States in relation to other countries,” with the result of “leaving American workers–who [sic] I love–. . . to absorb the cost in terms of lost jobs [and] lower wages,” he concealed the actual economics of withdrawing from the Accords were buried beneath boasts to have secured “350 billion of military and economic development for the US” and to help American businesses, workers, taxpayers, and citizens.  

In continuing to dismiss the data out of hand about the expanded production of greenhouse gasses, Trump seems to seek to overturn the deceptions of data visualizations that have alerted the United States and world about the consequences of unrestrained or unbridled climate change. Trump ridiculed the true target of the nearly universally approved Accords, scoffing at the abilities to reduce global temperatures; instead, he concentrated on broad figures of lost jobs in manufacturing and industries that are in fact small sectors of the national economy, and incommensurable with the dangers of ignoring global warming and climate change, or the exigencies of taking steps to counter its recent growth.

As if years of accumulated data of earth observation could be dismissed as deceptive out of hand by executive authority, independent of an accurate judgement of its measurement, Trump dismissed expert opinion with the air of a true populist whose heart lay in the defense of the American people and their well-being–as if they could be abstracted and prioritized above the world’s  Trump’s largely rambling if gravely delivered comments in the Rose Garden press conference that painted himself as daily fighting for the country cemented the alliance of populism and a war on science by its odd substitution of bad economic data for good scientific data.  

The switch is one in which his administration has specialized.  His address certainly culminated an outright dismissal of scientific conclusions based on a distorted America First picture of the world, where a stolid declaration that “the United States will withdraw from the Paris Climate Accords” made sense as form of national defense–despite the potential global catastrophe that rising global temperatures and sea surface temperatures threaten. Is the technique of juxtaposing statistics and muddying data an attempt to undermine evidence, or an illustration of his insecurity with giving authority to data, or to scientific authority, the mirrors his concern about concealing “his profound illiteracy,” or his insecurity about illiteracy, that linguist Geoffrey Nunberg argues not only distance his own speech from words, and discredits their currency, but an insecurity of having to rely on language and linguistic skills alone, in ways that might be well seen as analogues to his plentiful use of all caps on social media, as stepping outside of the language of public life to a medium more direct and complicit with his audience, if outside the usage standards of a written language.

The catastrophes were minimized by being argued to be based on “discredited data” in a bizarre flourish designed to dismiss scientific concensus  Trump conspicuously faulted not only the “discredited” but distracting nature of data  in the speech he gave in the Rose Garden on June 1, 2017 that supposedly justified his announcement of withdrawing from the Paris Climate Accords in 2015 to limit heat-trapping emissions of carbon fuels that have been tied to observed climate change.  Rather than foreground the international nature of the accords among agreed upon by almost 200 nations, trump advanced the need to heed local interests, perversely, but even more perversely argued that the Accords resulted from disinformation.  He spoke to the world to chastise their recognition of scientific observations, in so doing destabilizing not only global alliances but undermining a long-negotiated climate policy by pulling the rug out from long accepted consensus not only of climate scientists but a role of national leadership that sought to remedy the failure of the Kyoto Protocol of 1997.  Trump turned his back on the Climate Accords on how to curb greenhouse gas emissions  by proclaiming their unfairness to American interests, and attacking unwanted constraints on American industry, through his own deployment of data that was even more discredited as an excuse to walk away from the prospect of a greener world.

1. If Trump steered the nation away from green energy and into darkness, Vladimir Putin seemed to mock Trump’s rationale for the withdrawal when he mused, jokingly but ever so darkly, that “maybe the current [U.S.] president thinks they are not fully thought-through,” making open fun of Donald Trump’s image of global leadership by wryly noting in ways that echoed the absurdity of Trump’s defense of the local in place of the global.  “We don’t feel here that the temperature is going hotter here, . . . I hear they are saying it snowed in Moscow today and its raining here, very cold,” Putin noted, as if relishing undermining long-established trends in climate data by invoking a populist championing of local knowledge as if it trumped the advantages of earth observation that satellite observation has long provided.   Populism trumped expertise and Putin laughed at the possibility that the Accords might soon fail as a result.

Given the longstanding desire of Moscow to be released from constraints on exploring the billions of tons of Arctic oil on which Russia has chosen to gamble, Trump’s almost purposive blindness to a changing environmental politics of the global economy astounds for its parochialism, and its championing of place to dismiss undeniable effects of climate change that seems closely tied to carbon emissions.  For with a false populism that championed the limited perspective of one place in the world–or one’s own personal experience–Trump dismissed the maps and projections of climate change, on the basis that the “deal” was simply “BAD.”  And as a man who views everything as yet another deal, while he pronounced readiness to “renegotiate” an accord he sought to cast as a failure of President Obama to represent America’s interests, the rebuke fell flatly as the accord was never designed to be renegotiable.

Putin’s remarks were met by scattered laughter of recognition, and some smirks at the decision of the American president to withdraw form a long-negotiated set of accords to the collective dismay of our military and environmental allies, and its implicit endorsement of deniers of climate change.  The potential “axis of mass destruction” France’s climate minister has cautioned against might indeed be one of mass distraction.  For in dismissing and indeed disdaining the historical accords to limit carbon emissions, Trump sought a soundbite sufficient to stoke suspicions the climate treaty.  He sought to cast it as yet another deeply rigged system of which he had taken to compulsively warning Americans.  Such a metaphor of bounty was jarring to reconcile with onerous economic burdens cited as the prime motivations for deciding to reject the Paris Accords on Climate Change.  The jarring cognitive coinage seemed to connote its negative by a disorienting litotes; but perhaps the most striking element of the entire news conference was that Trump offered no data that backed up his own pronouncements and appearance of steadfast or only obstinate personal resolve.

Before the coherence of the embodiment of climate change in maps, Trumps jarringly juxtaposed radically different sorts of statistic to snow the nation–and the world–by disorienting his audience, on which Trump turned to a litany of complaints and perceived offenses striking for providing no data of any sort, save several bits of false data.  As much as Trump betrayed uneven command over the data on climate change, as if embedding discrete numbers in unclear fashion that supported a self-evident argument, as if they addressed one of the most carefully documented changes in the atmosphere of the world.  By juxtaposing a threat that “could cost Americans as much as 2.7 million lost jobs by 2025“–a number described as extreme but decontextualized to exaggerate its effect, framed by the dismissive statement  “Believe me, this is not what we need!“– with a projected small temperature decrease of two tenths of a degree Celsius–“Think of that!  This much”–as if to indicate the minuscule return that the “deal” offered to the United States that would have made it worthy accepting its costs–

sub-buzz-27555-1496436714-1

The gesture seemed designed to juxtapose the honesty of direct communication with the deceit of the experts.   Trump’s notion of direct communication concealed the surreal enjambment of disproportionate numbers more striking by the difference of their scale than their meaning.  Of a piece with his citation of partial statistics that exaggerate his points, from “95 Million not in the U.S. labor force” as if to imply they are all unsuccessfully looking for work, targeting some 8 million immigrants as “illegal aliens”ready for deportation, or how immigrants coast American taxpayers “billions of dollars a year.”   Such large figures deploy discredited data difficult to process to conjure fears by overwhelming audience, distracting from specific problems with large numbers that communicate an illusion of expertise, or even overwhelm their judgment by talking points disseminated in deeply questionable media sources.

If the power of this juxtaposition of unrelated numbers gained their effectiveness because of a lack of numeracy–Trump’s claim of 100 million social media followers lumps his followers on Twitter, Facebook and Instagram, many of whom may be the same people, and other fake persona —the numbers seem to exist for their rhetorical effect alone, as if to awe by their size and dismiss by the miniscule benefits they might provide. The point of contrasting such large and small statistics was to suggest the poor priorities of the previous administration, and dilute form the consensus reached on the modeling of climate change.  To be sure, the Trump administration also barters in fake facts on Fox News Sunday. inflating the number of jobs in coal industries, that show a misleading sense of the government’s relation to the national economy, generating a range of falsehoods that disable fact-checking, obscuring the fact that the global marketplace increasingly gives preference to cleaner energy and clean energy jobs more quickly others sectors of our national economy beyond energy industries.  The ties of Trump’s administration to fossil fuels–from the Secretary of State to the Secretary of Energy to the Secretary of the Interior down–employ the obsfuscating tactics of fossil fuel industries to obscure benefits of low-carbon fuels.  Indeed, the inability to “renegotiate” a deal where each nation set its own levels of energy usage rendered Trump’s promise of the prospect of renegotiation meaningless and unclear, even if it was intended to create the appearance of him sounding reasonable and amiable enough on nightly television news.

Another point of the citation of false data was to evoke a sense of false populism, by asking how the Accords could ever add up.  In isolating foregrounded statistics great and small, tightly juxtaposed for rhetorical effect, the intent seems consciously to bombard the audience to disorienting effect.  We know Trump has disdain for expertise, and indeed the intersection between a sense of populism with disdain or rejection of science may be endemic:  in formulating responses to a global question like climate change that he has had no familiarity with save in terms of margins of profits and regulations.  Rather than consulting experts, the President has prepared for public statements by consulting sympathetic FOX media figures like Kimberly Guilfoyle who pander by endorsing the notion of a climate conspiracy–not experts, who use data as obscuring foils, suggesting an ecology of information originating from pro-fossil fuel industry groups.

We Think Our Shores Are Stable,–but Need to Know that They Are Not

All maps stake propositions:  as much as embody geographical information, they make arguments about how a landscape is inhabited.  But climate change maps that model future scenarios of warming, increasing dryness, sea-level rise, or glacial melting are propositions in a strict sense, as they construct frames of reference that orient us to, in the very ways Wittgenstein described propositions, “a world as it were put together experimentally.”  Shoreline change can be mapped in deep historical time, or over the past century, in interactive ways that reveal and allow us to zoom in on individual sites of sensitivity–

 

national_shoreline

 

 

–but the processes of mapping such change cannot rely on contour lines drawn on a base map.  For to do so is to abstract a static photograph from a global process that they only compel one to try to better visualize and comprehend.  The processes of change are extremely complex patterns of causation that exceed most map-viewers competencies, despite the wide diffusion of claims and counter-claims about global warming and climate change in public discourse, which has effectively increasingly threatened to dislodge the preeminence of any position of expertise on the issue, demoting the actuality to a theory and removing many public statements on its existence from the map of coastal change, or the relation of the land to submerged territory.  We are in danger of adopting an increasingly terrestrial or land-locked relation to how climate change affects shores, because we map from the boundary of the landform, as if it were fixed rather than a frontier of interchange and exchange, both above an under ground.

Far more than other maps, maps of climate change demand unique training, skills, and education to unpack in their consequences.  And when the propositions staked in maps of climate change have increasingly come under attack for political implications, as if the scenarios of climate change are formed by a cabal of data scientists and climate scientists to advance independent agendas, or a poorly articulated and politicized climate research, it seems that the special skills used to interpret them and the training to view them have come under attack for not corresponding to the world.

Real fears of the danger of the delegitimization of science run increasingly high.  But attacking the amazingly dense arrays of data that they synthesize seems to suggest an interest in shutting down the very visualizations that allowed us to conceive and come to terms with climate change.  The open suggestion that digitized scenarios of climate maps were only designed to terrify audiences and advance interests not only undermines discussion and debate, but seems a technique to destabilize the emergence of any consensus on climate change.  Although the fears of an immediate loss of climate data may be overstated for the nation, the loss of a role in preserving a continuous record of global climate data is considerable given fears of reducing space-based remote sensing.  Such observation provide one of the only bases to map global climate data, ranging from aridity to water temperature to temperature change over time.  The hard-line stances that Trump holds about climate sciences are expressed in terms of the costs they generate–“very expensive GLOBAL WARMING bullshit,”–but extend to denigration of climate scientists as a “glassy-eyed cult” by science advisor William Happer–who in George W Bush’s Dept. of Energy minimized the effect of man-made emissions on climate change.

Both bode poorly for the continued funding of the research agenda of NASA’s earth sciences division.  And the need to preserve a more coherent maps of man-made climate change grow, choosing the strategies to do so command increased attention.  The dangerous dismissal of climate sciences as yet another instance of “listening to the government lie to them about margarine and climate change” or prioritizing the political impact of their findings to draw attention to global warming and climate change seems to minimize the human impact on climate and recall the censorship of climate science reports from government agencies by governmental agencies and political appointees from a time when de facto gag orders dissuaded use of the term “global warming” over a period of eight years, a period of the harassment and intimidation of climate scientists. The term of “climate change” seemed agnostic of human agency–unlike Al Gore’s conviction that “global warming” was a global emergency.  As well as actively destabilizing ties between human-caused emissions of carbon dioxide and other heat-trapping gases with global warming, Bush asked government agencies investigate “areas of uncertainty” which his successor tried to clarify through explicit research goals.

Yet the role of maps in making a public case for climate change and its consequences seem to have made the project of climate tracking and earth observation under increased attack, as the project of mapping climate is in danger of being removed once again from scientific conclusions about global temperature rise, subsurface ocean temperature rise, or glacial melting–as the ways that climate change maps embody actual environmental risks is effectively minimized.

Melting Boundaries and Frozen Pasts: Anthrax, Globalism, and Climate Change

The first six months of 2016 brought the greatest increase in global warming in recent years, and a rise in temperature that far surpassed all previous records–and occasioned a rapid melting of polar ice challenging to map as well as to imagine in all its cascading consequences.  The 378th consecutive month of land and water temperatures far above twentieth-century averages, as per the World Meteorological Organization, became an occasion to wonder how “many more surprises are ahead of us”for the director of the  World Climate Research Program, and brought the arrival of strikingly new consequences of climate change with the unearthing of unmarked graves, as the once-fixed boundary to what had constituted the northern boundary of continents has begun to retreat.

A set of such surprises have already arrived.  The increased melting of what were once thought permanently frozen regions of arctic permafrost first awoke dormant but contagious anthrax.  While this latest development provided a note of panic, it seems only emblematic of the eventual cascading of after-effects that the melting of the arctic stands to bring, and of the difficulty to place them in any coherent narrative.  Yet while we use maps to organize a range of data on climate change, it’s also true that the emergence of anthrax in the Siberian tundra provides a poignant illustration of the “surprises” that climate change will bring.  And while the world has not known smallpox cases since 1977, the contraction of the permafrost stands to reveal extinct smallpox, and indeed prehistoric viruses of up to 30,000 years old, as cattle graves are newly exhumed from permafrost.  The last smallpox epidemic in Siberia dates only from the 1890s, but the buried bodies by the Kolyma river have appeared as if by unexpected time-travel with Smallpox DNA, raising the possibility of with the unearthing of riverbanks, and  sites of burial of both infected animals and diseased bodies as the ground thaws.  Areas infected with anthrax spores release by preternatural global warming are being cordoned off, but the revived viruses and spores may travel widely in water in ways difficult if not impossible to map.

As we seem to be opening up much of the north pole and an Arctic Ocean for multiple new shipping routes, in ways that have led to projections of expanding trade-routes with names that reference imagined passageways like the Northwest Passage, the imagined increased shrinkages and thinning of layers polar ice due to global melting are understood as opening up new routes to nautical shipping as ice retreats from much of the arctic regions–but which, if they were only understood in the abstract in 2013, are now becoming increasingly concrete in the range of consequences that can cascade from them.

The arrival of a period of pronounced decline in arctic sea ice has produced a newly palpable intimations of the vanishing of what were once expanses of ice.

Mapping a Century of Rising Heat

RISING Temperatur esNew York Times

The color-saturated mapping of regional changes in temperature across the contiguous United States provided a commanding visual for the front page of the New York Times of May 6 to capture changes in the US climate:  placed on  conspicuously above the fold and standing alone, just below the headlines, the graphic served multiple functions in a strikingly effective way.  The weather map that was first released by the Obama White House elegantly and effectively served–in ways that words could not–to combine several narratives of climate change that synthesized  the findings of a recent committee of scientists on the wide-ranging effects of global warming.  This is an unprecedented victory of the map, the most effective single tool to describe the complex process of a veritable cascade of environmental shifts, by selectively focussing on a known variable of local warmth.   The orange and bright reds of the map arrest the eye in ways an article or headline could not, and effectively provoke a cascading set of side-effects and reactions to occur in readers’ minds that served to grasp the finality of warming’s consequences.  As one mind quickly moves off the map of stark changes of temperature to the effects of future droughts and increased aridity of soil, consequent crop-shortages, and subsiding ground-levels, imagining the marked depletion of cool air, streams and rivers that would dry, and an increasing dependence on energy to create artificially cool environments. 

Although it is static, the historical map suggests a spectral future forecast for the nation that dramatically moved from back pages to headline news.  It mirrored a roll-out of the announcement as part of a dialogue with weathercasters on television news programs in a gambit to engage the public in the question of climate change.  Indeed, the graphic mimicked the presentation of weather maps on TV, images of the national forecast that the Weather Channel has made all too familiar.  Even if the map documents changes of the previous century, it shares the iconic status of the sort of severe weather forecast that The Weather Channel has accustomed us to interpret and to see.  We’re now trained so often to interpret and to read similarly colorized  climatological forecasts to trace regional emergencies that the Times‘ map seemed to recuperate these conventions to make a polemic point not so much about the past–“US Climate Has Already Changed”–but about the possible futures that the map forebode.  For weather maps offer the most acceptable medium of future predictions, where they have currency as credible tools for short-term forecasting.

Thuderstorm Forecast

The range of information in the map that summarized a century of rapidly shifting local climate temperatures How could such a gamut of consequences be convincingly understood or presented other than in a map?  The visual immediately triggered multiple questions of effects on species, forests, farmlands, new sorts of vegetation, and shifting insect populations described in the article, which a reader some decades ago would be challenged to link.   The effectiveness with which the map implicitly summarized the ramifications of these potential changes, or provoked its readers to react to its orange and read heat-distributions, presented an ominous vision of the future, as well as the historical past of a century of warming weather that the headline announced.  As if with the ominous fatality with which science fiction authors like Arthur C. Clarke described the future of a world battered by asteroids, the map opened up a view on the consequences of environmental change in a future world, even if its headline announced an event firmly rooted in the past century, synthesizing as it did the findings of two periods in the past hundred years.

The finality with which the map released by John P. Holdren documented a change that had already occurred across the nation’s regions, but made it to every weather bureau and station across the country, as if to maximize the newfound familiarity of audiences to engage meteorological maps as a way of making its own polemic (and of course partly political) point of how drastically rising temperatures stand to redraw the familiarity of the world.  Extending far beyond earlier warnings  voiced by the UN, or the pronouncements of an Inter-Governmental Panel on Climate Change whose  report documented the melting of the ice-caps and collapse of sea ice in the arctic, the migration of many fish out of their habitats, and impending dangers of rising seas.  Perhaps these global images were too remote, or difficult to visualize.  The powerful invocation of the weathercaster seemed to give greater reality to the scary prognostic in the contiguous United States, and concretized the multiple threats of climate change in an image that confirms the changing nature of the ground beneath our feet.  Some may criticize the focus on the United States alone in an interconnected world, as if the isolation of our country’s climate somehow removed it from a global problem and dilemma, or placed undue emphasis on the effects of emissions on the climate in the US.  But the image of actual experiences spurs a call for reaction and response, and, in an echo of the tactics of the Obama administration, reveals the increased “cartographical literacy” in the reading and interpreting forecasts in persuasive national weather maps.  

Forecast and Warming

The emulation of the televised weather forecast is no doubt what makes the map appear so immediately effective.

The map of the entire country was in ways a counterpart to the images of November 2012, around the time of Hurricane Sandy, simply titled “What Could Disappear,” which asked viewers to imaging the shifting coastlines of rising seas, and pictured the coasts that rising ocean waters could redefine, submerging beneath the sea low-lying areas of what we consider habitable land–as well as flooding all of Galveston, TX and some 45% of Long Beach.

 

What Could be Lost The New York Times
 

But rather than engage with complex claims of climatological futurology, the front-page graphic was both at the same time historical in perspective and even more apocalyptic.  In announcing or intoning “US Climate Has Already Changed,” it reminded us of the consequences of rising temperatures at a historical remove that was still part of our present and an uneasy glimpse to the future we have mad, using tense whose finality foreclosed debate in quite incontrovertible ways.  The map’s comparison of temperatures over a century effectively resolved debates, separating the actual consequences of climate change on a familiar environment from debate about its mechanism and reminding us of its man-made origin, and untangling the dangers of the changes that it wrought from the cascading (if terrifying) mechanism of ocean levels rising, habitats altering, fish migrating, the extinction of species, and deaths of coral reefs.  The map was able to link itself to a multiplicity of lived experiences and actual fact, and conjure a scarier–precisely since undefined–picture of what was to come–an era of increasing heat.  (Its associations might almost be as apocalyptic as the hallucinatory surreal  dream from a 1959 episode from Rod Serling’s The Twilight Zone, “The Midnight Sun,” in which the earth exits its elliptical orbit and moves toward the sun, warming the nation so much as to induce crazed radio weathercasters to stray incoherently off script and panicked Americans to flee abandoned cities en masse to Canada in search of cooler climes.)

The particularly powerful graphic of the map of regional variations in rising temperatures was quite devastating in its depiction of how–despite some regional differences–none save rare pockets of settled land experienced anything approaching a decline in reported weather temperatures.  For those that did, mostly concentrated in the lower Mississippi basin, they experienced quite slight declines:  it presented an image of a continent on fire, almost about to be consumed by flames, burning from its edges, if, the accompanying article noted, increasingly soaked by torrential rains.

RISING TemperaturesThe New York Times

The  growth of areas already warmer on an average of some two degrees suggested an encroaching of scarlet red blotches across the land from all sides, particularly in southern California and Arizona, Utah and New Mexico, the northern eastern seaboard, and the Great Lakes, with Bob Dylan’s native Hibbing seeing the greatest temperature change of over a massive three degrees.  The map powerfully synthesized the effects of human-induced climate change in ways that are not only impossible to rebut, using findings of a national  committee that has been in existence for over a decade–but was by far the most effective among the various interactive graphics it released.  The simple synthesis in a four-color map of the contiguous US immediately showed rising temperatures in some of the more inhabited areas of the nation, from New Mexico to Southern California, to the New York-Washington corridor.

In selecting a map to represent the consequences of climate change that were detailed in the report, the images suggested less of an infographic than a sort of disease map of a climate that has gone off the tracks.  Even if it might be faulted from its insistence on removing the US from the world, and focussing on one place within a complex web, as well as flattening its findings in cartographical form, the image is powerfully links the land to a set of abstract changes we cannot fully comprehend, but whose effects we can perceive.  This is the stunning victory of the static map.

Green Urbanism? Blue Urbanism?

Since maps invite their viewers to enter an image of the natural world, as well as to relate places to the broader geographic context in which it lies, they offer increasingly useful perspectives to relate the ocean to the land.  The perspective they offer on all regions has long been rooted on the land,  however.  And the coasts–and indeed the dangers–for adhering to such a “landlubberly perspective” on our rising oceans are increasingly apparent.  A perspective that privileges mapping inhabited lands –and orienting viewers to a set notion of place–places us at a particularly disastrous disadvantage when assessing questions of climate change, or reacting to the increasingly lethal storms, tsunami, and typhoons encountered as the inevitable consequences of climate change, and that coastal cities–from New Orleans to New York to the devastated Philippine coastal cities of Tacloban, Ormac or Baybay–seem condemned to repeat.

In continuing to rely on maps whose perspective denies that of the future expansion of oceanic seas, we threaten to lose perspective on our changing relation to the sea.  We have long found threats of the invasion of ocean waters difficult to integrate in an inherited image of the city as a bounded entity, and continue to draw clear lines around the cities in which we dwell:  our maps draw clear lines between land and water.  Perhaps this is because waters seem so difficult to circumscribe or bound, and the fluid relation between land and water difficult to render accurately or draw.  When an influential movement of urban architecture and planning calls for a greater integration of the natural world–so often bound outside of cities or city walls–within urban entities, they retain the notion of the bounded city.  Recuperating the term the entomologist and biologist E.O. Wilson coined, “biophilia,” to express the “innately emotional affiliation of human beings to other living organisms” in human nature that demanded attention, they argue that cities need to promote contact with nature, since, Wilson argued, such contact provides a spur to creativity, productivity, and well-being.  The planning of “biophilic cities” is dedicated as a movement of urban design to “contain abundant nature” in their structure.  The championing of “model cities”–such as Perth or Singapore–are promoted as examples of the “biophilic” age of urban architecture.

Yet are these models (often located in semi-tropical climates) not limit cases where we can most easily integrate oceanic waters into a built environment?  For by isolating the city as a unit in which to restore nature, there seems more than a bit of bio-fetishism in singling out new spaces where blue waters can enter an urban environment:  the optimism of its evangelical tenor as a movement of urban planners, dedicated to reframing the reintegration of cities with the watery surroundings has gained a broad charge and dedicated following, including partner cities that border on water such as San Francisco, Portland, Milwaukee, Vitoria Gastiez (Spain), Birmingham (England), and Wellington (New Zealand).  While the benefits of such urban architecture appear considerable, the challenges for expanding the role of the ocean in the horizons of city-dwellers seem only the start of restoring the historical isolation of the city from watery life, or integrating the oceans within our future urban planning.

The movement of blue urbanism is an illustration of courageous dedication to a project of reintegrating aquatic and urban environments–at least, presumably, before the shores of cities will be redrawn by ocean waters.  The considerable cognitive benefits claimed for these more enriched urban networks build on movements for integrating networks of urban “green-spaces”–including not only parks but green-belts and even forests is a reasoned reaction to urban sprawl and overbuilding and way to take charge of the built environments we create.  “Blue urbanism” would comprehend a watery frontier, offering opportunities for immersing children in rivers, urban parks, watery excursions, and underwater ambients which surround cities.   Blue urbanists espouses an improved integration among the fauna and flora lying near aand around cities within something like a green belt–and espouse the value of an analogous “blue belt” as a way to foster a new attachment to the waters and their shores, rather than seeing them as limits of built city.

Yet does emphasis on the human benefits of such contact carry a all too narrowly restricted notion of what a watery surrounding might be?  The watery oceanic borders of cities are in themselves rarely mapped, though the shifting waters of the Gulf Stream and other currents determine the shoreline inhabitants of North America, but might a map provide a fuller perspective on the interchanges and ecosystems lost by drawing firm barriers between urban and ocean life?

1.  The “blue urbanism” that Timothy Beatley advocates wields the rhetoric and best practices of green architecture’s “integrated network of urban space” to invite us to re-imagine cities’ relation to the shores on which they border.  Yet there is concern that such projects of rebuilding turn away from the depth of our historical remove from the waters that surround our cities–an increasingly pragmatic concern after the very fragility of this divide has been so traumatically revealed in recent decades, from damages inflicted on US cities by Hurricanes Katrina and Sandy or, afield, the Indian Ocean Tsunami and super-typhoon Haiyan.  The ecology of biophilic design, for all its benefits, could benefit from a broader global ecology, basing itself less on the benefits of human friendship with the biosphere, and being more oriented to global contexts of the cost of climactic shifts by looking back to the geography of the past–lest the affections of biophilia border on the bio-fetishism of the philistine.  The precepts of adaptation and resilience to mitigate bad policy decisions are of intense importance; historic maps offer base-lines to qualify the alienation of cities from their shores that compliment the need to build green and blue belts.  The maps we have drawn about urban areas may provide a basis to recuperate the integration of life along the shorelines we have lost, in short, and the nature and settlement of life along the city’s shore–as well as the ways that oceans serve less as a barrier to than interface with the shore.

While we map the trespass of waves over the finely drawn boundary lines of territories, measuring incursions across demarcated shorelines and property lines, and mourning the scope of damages and loss, we seem to remediate via maps–much as how OSM-mappers have begun to chart buildings and routes in the Philippines for delivering humanitarian supplies, as a way of rebuilding, if at first in virtual form–to restore urban infrastructures in digital form.

Yet these maps do not comprehend, for lack of a better word, the sea.  The terrible human costs of each of these events serve as something of an intimation of the threats global warming poses to urban environments, and invite rethinking notions of ‘planning’ replacing the imagined stability of  a built frontier of urban society with a more permeable line of inter-relations, even as we come to appreciate how little conscious “planning” went into the drawing of earlier boundary lines.  Both the human and material costs of these events compel an appreciation of the role of the shoreline, as well as intimations of the threats global warming poses to urban environments and indeed the world we have built.

Naturalists have recently begun to realize the power of maps to invite reexamination of our relations to place, however–often by using historical maps to excavate the shifting historical relation to the natural world that have led us to draw such finely parsed lines between planned urban environments and their surrounding waters to assess the costs of these sorts of fantasies of spatial distinction:  if we don’t build on the water, we cannot ignore it but at our collective peril.

Map offer a particularly precise if plastic means to situate place that are able to register deeper, less easily visualized, chronological changes and global contexts, or shifts within a regional ecosystem that would be otherwise difficult to conceive.  In age of rising oceans and global warming, maps draw relations between local settings and global changes to help assess the extent to which global warming threatens to obliterate or erode the stability of our concepts of place.  Maps of the circulation of waters around specific cities compel us to rethink an inherited oceanic boundary.

2.   Can a “blue architecture” invite us to re-imagine bifurcated schema of ordering of space to which we have reduced the relation between land and sea to a simply drawn line?  Or have we lost a relation to the land that a new building project cannot recover without clearer lenses to view the relation between water and planned environment, and to be invited to appreciate a clearer register of the relations between coastal cities and the surrounding sea, and, indeed, of the delicate interdependencies that are the basis for our sense of place, and underwrite how we imagine “place” as a category?  A historicized art of mapping stands to call attention to the ecosystem that might lurk beneath the threat of climactic change, and understand the changes they pose to local ecosystems.  The art of mapping provides unique tools to invite viewers to consider local settlements, and develop tools to re-imagine a relation to the sea new building projects alone cannot foster.

Sanderson's Base Map

We can appreciate the huge changes wrought in a relation to the shore by how a cartographical reconstruction of Manhattan island revealed in this stunning 1782 British Headquarters map drawn at the painstaking scale of 6 1/2 inches per mile reveals the island’s coastline as it was experienced by Lenape tribespeople.  Using the watercolor map as the base-map for his digital reconstruction of the local environment, landscape ecologist Eric W. Sanderson of the Wildlife Conservation Society worked over five years to create GIS database, geo-referencing landmarks and sites to reconstruct the forgotten landscape based on 200 control points.

Sanderson’s completed map has a beauty that invites viewers to explore a computer generated landscape’s verdant arboreal landscape and rich wildlife, moving with amazing apparent precision over a web of lost streams, rivers, and hills that agricultural and urban development erased over time–most all of the more than 570 that distinguished the island Lenape members to give the name “Mannahatta,” the ‘island of many hills,’ and to map over 627 varieties of plants in the island, and the 233 types of birds and 24 different mammals who lived in its delicate interstices of interlaced ecosystems, in its swamps, ponds and the estuaries of its shores.

The older shoreline strikingly engages one’s mental map of Manhattan’s shore.   It jar one’s notion of place, and shift the stability of shorelines, streets, and riverine banks within one’s head.  Superimposing data from a Google map visualization of the verdant forests, ponds, streams, and marshes before four centuries of landfill shrunk its coastal geography, the map reveals a huge change in place in a powerfully persuasive graphic form.

Indeed, the superimposition of the shifted maps–the street grid and coastal drives laid above the earlier contours of the island’s expanse– is compelling by the complex cognitive dissonance it creates, placing multi-lane expressways and drives on the expanded edges of the island, so that they run across the marshland estuaries of the Lower East Side or cut into the blue waters around the island, suggesting the actual de-naturing of the landscape even more than the de-naturing of place that all Google Mapping templates seem to afford–and far more eerily reminding us of the extent to which we’ve effectively distanced ourselves from the expanse that the island once occupied as well as the ecosystems that it held.

3.  The remove of the world of this island situated on merging saltwater and freshwater, and with a dynamic verdant ecology is apparent from Markley Boyer’s stupendous digitization, which recreates the island seen by Henry Hudson in 1609, and which, if not a map per se, compels us to both explore its content by mapping them against our own experiences and spatial imaginaries.  The almost palpable landscape invites us to explore its content, as if as it invited Henry Hudson and his men in:

These now absent beaches, marshlands, and estuaries in the landscape offer a striking contrast to the current shore.

Mid-Manhattan
The integration of its coasts to the river echo the shorelines that John Randel, Jr. famously mapped in delicate watercolors in a detailed rendering of its many hills between 1818-20, even as the grid of streets was lightly traced and projected above a far less level urban topography, where the city descended in differently manners to the rivers and estuaries on its shorelines, most of which have been erased by time:

Boyer’s glorious digital reconstruction recreates the shimmering presence island of hills, rivers, and trees that Lenape knew in its speciated glory, mapping the messiness of that shore in ways that inspire a vision of or compelling case for the optimistic dream of restoration of these shores:

4.   Maps offer persuasive forms to re-think cities’ relations to oceanic shores, perhaps more compellingly altering deeply set attitudes than new practices of planning to integrate more fluidly and esthetically water and land.  Although Beatley calls, at http://www.biophiliccities.org, for new attitudes to the surrounding world, and fostering a new culture of lifestyle, curiosity, and an integration of the tactile presence of the seas in “blue urbanism,” we  might better appreciate the nature of the frontier created between city and water not only in the benefits of immersive aquatic environments in cities, but respond to the absence even of registering seas in urban planning by examining how we came to map a disconnect between cities and ocean– and the cultural divide that has emerged between shore and urban space that was elaborated from the mid-nineteenth century, and is now deeply established by zoning, districting, EPA standards and urban planning texts.

In asking to extend our concepts of cities to the oceans that surround them, we might work not only to make new maps, but use old maps to be mindful of the need to extend our sense of place through the refiguration of urban spaces–noting how maps mark and register the depths of the cultural divide between urban and oceanic space, and examining maps to chart the losses of a shifting historical relation between the city and ocean.  Such a remapping of the city’s relation to the land is echoed in the recent interactive mapping project of Stamen Design, Surging Seas, which tracks rising sea-levels caused by storms or flash-floods, mapping sea levels in relation to the inhabited land–and visualizing a nine foot rise in sea-level of nine feet, here in lower Manhattan, based on data from Climate Central.

And the interactive site allows one to track what changes would happen if the sea-level were to rise it to a ten full ten:

5.  At a recent discussion in San Francisco’s Exploratorium about relations between land and sea promoting such a “Blue Urbanism,” the relations between place and global change rightfully gained considerable attention.   Most presentations focussed on specific examples of cities, but the problem was pressingly (and depressingly) relevant given the recent typhoon.  Occurring in a room exhibiting such splendid shifting nine-panel global color video projections, courtesy NASA’s LandSat satellite photographs or the Goddard Flight Center, of Global Precipitation Levels, Sea Surface Currents and Temperatures, Ocean Currents, or, below, Global Aerosols, they seemed to provide a unique context for rethinking the presence of the local in relation to the sea.  For only in rethinking built relations between land and sea, and the compartmentalization that led to the diffusion of aerosols, the shifting of water temperatures, and  changes in the level and salinity of oceans over the past one hundred years, can we measure the human footprints already left on environment.

Global Aerosols Exploratorium

One such remapping of such relations and attitudes might begin from maps, it began to appear–and from the inspiration maps might provide to remap relation around San Francisco, not only by seeing how space was filled by the city–or the urban conquest of space–but rather how the negotiation of the boundary with the sea was based on spatial practices of such longstanding nature, entailing and perhaps rooted in the representational practices of defining space as an area of settlement and urban planning–and a practice of planning that sees space as filled up by housing projects that cut off the marine space of the sea.

The projected maps on plasma screens raised questions of how to rethink the sedimentation of such deeply set cultural practices, if only by providing a context for the dramatic remapping of urban environments at a remove from the ocean’s ebb and flow–or relate place to a far broader context of environmental change.   When Rebecca Solnit recently offered a haunting analogy between global warming to the processes of gentrification that threaten the fabrics of urban neighborhoods–both occurring with blinders to the overall structure and coherence ecosystems, whether the social ecosystem of urban space or global ecologies, and of removing oneself from our role in creating a scenario of global warming or urban change.

6.  The history of spatiality and of spatial practices that define the city may suffer, one soon realized, from the separation of such “spatial practices” from an appreciation of urban environments.  The circumscription of the spatial is partly inherited from the conceptually pioneering–if idealizing– strain of thought in the work of the French sociologist Henri Lefebvre, whose notion of in The Production of Space was rooted in an Aristotelian or Kantian categorization of space as a human creation.  For when Lefebvre distinguished forms of apprehension among social practices, representations of space, and symbolic models of spatial representation, he refined how Aristotle cast position as a category of human apprehension and Kant affirmed space as an attribute of human judgement–rather than an ecological space of multiple species’ interaction, or indeed of biological overlap.  Instead of commodifying space from a human point of view, we fail to register either local specificity or the density of coexistence around place:  maps can return attention to all too often forgotten margins of settlements, and effectively reconstitute place in a greater environment.  A similarly broad sense of the sea-shore as a “primeval meeting place of the elements of earth and water, a place of compromise and conflict and eternal change,” as much as opposition, was suggested by Rachel Carson, who suggested the basis for understanding the shorelines by “the long rhythms of earth and sea that sculptured its land forms and produced the rock and sand of which it is composed”–and the biological communities specific to each.  She chose a map of the Gulf Stream as a sort of emblem for the situated knowledge of the shore, using a version of the 1769 chart of Benjamin Franklin based on the working knowledge of a Nantucket sailor, Timothy Folger, that is the end-paper for her 1950 The Sea Around Us; Carson praised the map for transmitting understanding of ocean currents–and for the first time locating the course of the equatorial Gulf Stream, or “Gulph Stream,” on a map, in ways that embodied a tacit familiarity with the flow that many sailors well knew, but which Franklin, as Postmaster General, was frustrated to find absent from any chart.

The recovery of the rare original Franklin-Folger map showed a pointedly less centrally defined Gulf Stream than the composite map reprinted above, but illuminated a new need for mapping oceanic expanse–in this case, for the postmaster general to elucidate the greater time needed to traverse the Atlantic from England, which world maps or charts had long excluded, in failing–or, more accurately, not knowing how–to map the seas.

Franklin- Map

7.  The question then becomes how to adequately map the seas, as much as urban space.  The ability to register and communicate familiarity with place–and with a watery space–is particularly lacking in most urban maps.  The absence is a considerable difficulty for adequately registering knowledge of the sea on its own terms, or the shoreline and its inhabitants.

Or can we use maps to register a shifting knowledge of the ocean’s shore?  One charge for spatial history would be to excavate the construction of space in different environmental contexts.  If it is to extend beyond the recapitulation of space as a human construction, “space” might be more adequately placed in a global–and less of a human–context by recognizing and affirming space as an ecological category.  One place to start would include the negotiation of deeply set cultural categories of division and differentiation that are framed in maps, taking the map as a human artifact–rather than a representation or a practice, a model of interaction that conditioned and provides evidence of lived experienced.  For the tendency to idealize space at an Apollonian remove–an image perpetuated, to be sure, in maps which subject the cognition of space to human understanding–abstracts space as a category of apprehension, rather than registering the density of interaction through a suitably “thick mapping” across boundaries, borders, and regional change that recuperate buffer zones, watersheds, and shorelines we have lost–in ways the art of mapping is uniquely suited to portray.

The challenge of recuperating the network of estuaries and streams that once surrounded the low-lying areas around the San Francisco Bay, for example, might negotiate with how we constitute the terrain for urban life by drawing a clear divide from the surrounding waters–or the perpetuation of the fantasy of drawing a clearly demarcated line dividing water and land.  Rising seas once flooded a river valley to create San Francisco Bay, whose many inhabitants  long existed in relation to a less clearly defined shore.  Maps can reveal how humans have interacted with the Bay over time that created deep mental barriers to interaction.   One can trace the shoreline moving in hundreds of feet inland, and slowing in past centuries to but a millimeter a year, or a city block over the last century, as a  shape-shifting feature with which bay residents have negotiated in different ways since a time when people lived near the bay, and negotiated with its salty marshlands, as a map of native American Shell Heaps that ring the bay eloquently reveals by noting the clear buffer zones that inhabitants created on beaches to meet rising tides.

BayShellmounds 001

The maps registers crucial details of the negotiation with marshlands and wetlands now lost or recently restored, outlining an image of interaction with the sea that is not immediately recognizable, and difficult to negotiate with our own changed landscape.

The particular coastal region near El Cerrito indicates the building up of these mounds to create a permeable barrier from the resident crustaceans along the marshlands running from north of Albany Hill to behind Point Isabel–now landfill, then a remote rock in the Bay.

The salt marshes, and the five creeks that fed them, are evident in this detail of the 1856 US Coastal Survey:

Yet as people moved inland from an 1850 shoreline was reduced by almost a third all of a sudden in last fifty years in a quite rapid and decisive manner, to create a new sense of the stability of the shoreline that segregated land and sea which will be particularly challenging now with the rise of sea levels projected global warming.  The illusory stability of the shoreline is however inevitable . . .  and the bay on track to expand again by 2100, to return to its size of 1850, in ways that pose disastrous consequences for such overbuilt regions of low elevations.  All low-lying areas are threatened by this projected expansion of the ocean, from Foster City to the treatment plants near to the Bay, to Oakland and San Francisco’s low-lying airports . . . and Oakland’s port.  In cities with waste facilities, oil tanks, refineries, ports and airports lie close to the water, as in Richmond, Oakland, the Carquinez Strait and Albany, ocean waters pose very real environmental threats illustrated by the tsunami’s breaching of the Fukushima Daini power plant.

8.  Can we redesign the shoreline differently?  Observing these low-lying areas that stand in close relation to the water in this map of 1850, we might consider the importance of beaches that can constitute a natural buffer to the shore, and the need for restoring their role as transitional zones and regions that has been so precipitously eroded in our environment.  For the erosion of such transitional spaces–and the overbuilding of the shores–has rendered more vulnerable low-lying areas such as Albany, Emeryville, Oakland or El Cerrito, encouraging blinders about the potential possibilities of future risk.

Sandy beaches that once circled San Francisco similarly served as barriers to the encroachment of the sea.  The loss of beachfront corresponded to a huge expansion of reclamation by landfill, and a resulting loss of estuaries, widely known around the Marina, and evident in the expansion of the city’s shores from an 1895 USGS topographic survey:

Lost Land SF-Historical Creeks and Shore marina detail

The loss of estuaries, creeks, and rivers in the entire peninsula of San Francisco since 1895 is less well-known, but even more dramatic:

SF Built Out:Loss from 1895 Topo

Will the process of getting to know the shoreline again provide a way to make them stable barriers once again?  Will we be able to provide natural resources by fluvial deltas, and support the growth of these buffer zones to do better on a second chance, by expanding an estuary system linking to the ocean that was so drastically mis-designed in the 1950s, when it was even proposed–if the proposal was reversed–to pour more landfill into the Bay, and re-zone the estuary, in order to fill an expanding housing market?

Bay or Rivewr

While it was not so prominent as the urban planners had proposed, the dramatic loss of such crucial buffer zones as tidal wetlands is evident in a comparison of first coastal survey of 1850  in this overlay of coastal maps, courtesy the San Francisco Estuary Institute, detailing the configuration of the coastline as it was and as we have made it,  over the century and a half of urban growth throughout the Bay Area–and the dangers that this poses:

baynature_829

The map cannot begin to conjure the shifting dynamic within the landscape and ecosystem we have lost–although the system of dykes and landfill suggests the beginning of the possible excavations of a lost shoreline.

This image of the expansion of the city’s urban claims to housing derives from a cultural and deeply anti-ecological view of the city as a site of stability–and ocean was seen as a site of antagonism on which, in the domesticated image of the bay, the city could rightfully expand–and the estuary be recast as a river to accommodate housing needs.   In starting to change our attitudes to our shorelines, and to view them as sites for other residents and as permeable barriers, we might start from changing our attitudes to the sea:  and remember, with Rachel Carson, that it is through our expansion of the “artificial” nature of cities that we have forgotten and somewhat brazenly rewritten our relation to the shoreline and the sea.

Maps, of course, forge bridges between nature and culture in provocatively engaging ways–and engage viewers by mapping these relationships.  If we are starting to remap place in provocatively interactive ways, the challenge is to best map the shifting relation between place and the global changes that call for an extensive remapping of place within the world.
