Losing Beaches, Losing Places

We have long considered man’s impact on the world, but are only starting to be able to chart the vastness of the scope of anthropogenic change. And wen it comes to the contraction of shores and beaches that has been forecast in current climate scenarios, the oldest of human environments, the shoreline and coast, seems in danger of drastic reduction at a scale we have rarely considered. The shifting littoral landscapse of the world have ben long neglected, if they are turned to each Earth Day for coastal cleanups and have been the site of intense preoccupations as a result of sea-level rise, as we have protected much of our national seashore.

But the prospect of an accelerated global erosion of coastal landscapes, and the loss of beaches, have only begun to be processed as triggering cascading consequences from disturbing ecological niches and coastal economies to the human relation to the natural world–a new relation to global ecology that we may well lack the vocabulary and structures to map on adequate scale to process, let alone discuss. But the mapping of coastal retreat that is projected for the coming century charts the magnitude of the scale of impact of human-created modification of a global environment in NOAA’s Fluid Dynamics Project calls for a broader reckoning of the impact on the global environment that stands to be created by coastal retreat akin to a global pandemic like SARS-CoV-2, and a remapping of the global shorelines that we have a very limited chance to come to terms with in any active context; terms like East and West don’t work in a climate catastrophe that does not differentiate not only nation states but that we lack the narrative categories to come to terms with in terms of economic inequalities, but suggest a crisis of global proportions that contrast with the delicate organization of space on shorelines near our home in their brute redrawing of the increasingly impermanent sandy shore projected for 2100, according to a rather modest climate change scenario.

The discovery of margin of the shoreline in the middle of the twentieth century as a privileged site of intense biodiversity risks obliteration as a particularly fragile ecosystem. Yet the shoreline habitat is now a site of unprecedented vulnerability. (The same stretch of sensitive shoreline habitat was quickly closed to comply with shelter-at-place directive, given the range of urban residents who drove to flood its trails, beaches, and shoreline as a way to find balance, many standing transfixed before the waves in a particularly stressful time, seeking purchase on a moment few could really grasp.)

The seashore seemed a natural place of reflection. But it was hard to imagine the sensitivity of these littoral lands. While the national seashore at Point Reyes is a unique preserved coastal environment, where eroding cliffs meet sands along broad strips of beach whose low grade offers habitat to coastal birds, grasses, and shellfish, in a meeting point of fresh and salt water, the beauty of the coast seemed a perfect refuge in a time of disorientation.

This blog has long discussed the specter of anthropogenic change, but in the panic of COVID-19, it seemed clear that we lack the mode to talk about the scale, continuities, and complexity at which such world-changing processes will occur. The future loss of shores would be quite difficult to imagine, even if one stares at the remote sensing maps that predict the effects of sea-level rise.. So many had voyaged to the shores as if by instinct during the COVID-19 coronavirus outbreak in 2020, from Long Island to Marin, to the extent of disturbing many coastal residents, who read searching for break from anxiety by acts of coastal distancing as an unwelcome promotion of the danger of importing viral spread.

In England and elsewhere, many departed from the city, in search of a new environment, by traveling to the coasts–where they were greeted, similarly, by protests by those who saw their arrival as a harbinger of infection. Many public beaches, concerned about close contact, have outright closed, as coastal communities do their best to dissuade visitors seeking to escape infection in Hawaii, Moab, Alabama, North Carolina or the Gulf Coast–in ways that cut us off from the shore as a place of reflection and rumination.

If undue media attention may be directed to bemoaning college students on Florida Spring Break, we must remember that Florida’s Governor, Ron DeSantis, ostensibly encharged with securing the state’s well-being and public welfare, stubbornly insisted on keeping beaches open in the state the shore until Easter, to allow “students to party” on Miami Beach, Fort Lauderdale, Clearwater Beach, and other “hotspots” of pleasure into hot spots of viral infection: DeSantis, never one to stop claiming higher ground, hypocritically or not, only turned his wrath on the partiers after facing a lawsuit from the state Attorney General, and even as communities closed beaches, refused to shutter state beaches to limit the spread of the Coronavirus that were a vital parts of the state’s economy–reluctant to close them until local municipalities intervened.

Shifting the blame to foreign travelers–and insisting on self-quarantining visitors from New York state or New Jersey–he sought to keep them open for business, by casting them as more vital than viral. DeSantis refused to accept the national scope of the problem, defending an economy that depended on tourism, elevating the economy over national health–and keeping them open a week after the closure of Disney World, after trying to keep a “six feet distance rule” to “stop large crowds from congregating,” as if the crowding was an issue, more than human proximity and contact–and refusing to take leadership on the issue by “deferring” to local government and causing confusion. As he reflected on the large number of elders in the state population, and their potential hindering of his own chances for re-election, it seems, did he alter his stance entirely, and beg the President to declare a national emergency, as the spread of the virus led to thousands of layoffs, with all non-essential businesses closed in coastal communities, as De Santis issued a state of emergency March 9, 2020.

Initial Florida Sites of Coronavirus Outbreaks of COVID-19 Infections/March 9, 2020

Meanwhile the COVID-19 data timeline by mid-March had spread across Central Florida, with cases of infection clustering on the shores. While the map that sizes the isolated pathogen as its symbol of COVID spread seems freakish, the telling newspaper graphic captures well the problem of coming to terms with the transmission of infections along the beach.

The abandonment of the closed Miami Beach–one of several citie that refused to keep its beaches open, as infection spread, as they knew what was really best for them–seemed to confirm the shore’s status as a natural site of reflection. The scope of projected reconfiguration of future shorelines would effect a deep change in the human relation to the shoreline, as much as the shoreline as a site of shelter and habitat.

For environmental geographer Clarence Glacken, the “traces on the Rhodian shore” were signs of civilization and the human modification of the environment that were fundamental to historical processes of change. The reference of the title of his survey of the modification of land through the industrial revolution took its reference point as antiquity–the image of the philosopher taking geometric figures drawn on the shores of Rhodes where he was shipwrecked as evidence of human habitation. The anecdote was prized by Vitruvius as evidence of the ability of geometry to frame the environment, and respond to it; Glacken took the image of the shores as a leitmotif for a magisterial survey of relations to the natural world that we now observe expanded and refracted in the remote sensing that tracks the broad impact of how industrialization has inscribed human relations to the environment far beyond Glacken’s four on the environmental influences on human history and man’s remaking of the environment. And the problem of the continued access to shores, and future of the shores, makes us go back to some of the early work of Glacken to recover its new relevance, if only because of our failure of models to come to terms with such massive anthropogenic change.

Mapping the Inequities of the Anthropocene

The notion of the Age of the Anthropocene has inspired an attempt to pinpoint the thresholds of contemporary environmental change.  The recent maps that register the shifts in the Air Quality Index at specific sites offer a way to register the impact of anthropogenic impact on the breathed environment that are especially compelling in tracing the momentous impact that man-made industry–and specifically the burning of coal–has in propelling global inhabitants into an age of the Anthropocene, and indeed in impacting local environments.  The changes of global climates pose peculiar difficulties of mapping by placing ourselves as viewers outside of the momentous changes they describe.  For the notion of mapping the arrival of the Anthropocene–or the signs of the visible impact humans left on the environment raises questions of how a map can trace the footprint humans have left on the earth’s biosphere.  If the epoch of the Anthropocene challenges one to position oneself outside the very processes in which one knowingly or unknowingly takes part, or indeed capture the consequences of a geological change in the biosphere to human life.

Do the differences of the AQI provide a sufficiently compelling map of the local dangers of potentially catastrophic environmental change?  Recent “revisionist ecologists” or self-styled pragmatists have called for forging or discovering possible “Paths Toward a ‘Good’ Anthropocene,” as Andy Revkin discussed at his New York Times Dot Earth blog, which stresses not the ecological evils of a narrative of global pollution, but the potential that values determine necessarily tough choices, striking debate that has reverberated in the Twitterverse as a perilous promise or a necessary evil under the hashtag #Anthropocene.  Revkin’s “Paths to a ‘Good’ Anthropocene,” has struck a nerve as subverting the core beliefs of Environmentalism by tweaking it with the prefix New, under the banner of eco-pragmatism.  One part of the basis for such “eco-pragmatism” seems to be the tired nature of the narrative of environmental ecology–or rather, of the alarmist hue that, for Keith Kloor, has morphed over the years from talk of a plundered planet a sixth extinction, and a baked planet to characterizing a planet under severe ecological pressure from multiple directions.  The narrative of the anthropocene, an odd term adopted in common parlance, narrates less a disaster than a widespread constellation of impacts of the human on our notions of nature, of sexual reproduction and differentiation, of genetic transmission, and on the geological record or livability of the atmosphere.

Can maps help this debate, by charting a differentiated view of “impact” and its geographical differentiation and spatial distribution, or in other words tracking anthropogemoc changes in hopes to mitigate its effects?

Can practices of mapping offer means to capture and conjure that constellation of changes, or tools visualize the momentous mechanisms of climatological change in which the human is folded into the environment–and economic activity inscribed in nature–that might most effectively communicate its arrival?  Can effects of the Anthropocene be tracked over space?  As Shakespeare imagined “his cheeke the map of daies out-worne” in Sonnet 68, as if the face were a map of temporal changes wrought by time,  so that “when beauty liv’d and dy’ed as flowers do now,/ Before these bastard signes of faire were borne,/ Or durst inhabite on a living brow,” the maps below of local levels of air pollution bear the scars of time and global capital. To track the disparities that mark the close of the Holocene is to trace the introduction of previously unforeseen limits on the expansion of human activities and indeed the sphere of human freedom.   While the entrance into the Anthropocene has been laid at the footstep of industrialized nations with considerable justification, rather than being understood only as a category of geological time, the odd currency of the geological term with a geography of the earth’s habitabilty.  

The difficulty–if not near-impossibility–of returning to a healthier presence of CO2 in our atmosphere “from [current levels] to at most 350 ppm” voiced by climatologist Dr. James Hansen–and the organization 350.org– might be less easily solved than they hope, and might even risk orienting discourse on the Anthropocene toward remediation and restoration of equilibria.  Indeed the hope for such a return to a level of safety from current levels surpassing 400 ppm are not only a huge change from early eighteenth-century levels of 275 ppm, may distract attention from the deeper consequences of the enmeshing of the human in the biosphere:  the deeper inequities of our globalized economy are revealed in a more variegated map of our entrance to the Anthropocene.   The disproportionate contribution of industrialized countries to carbon emissions create well-known ethical questions of the distribution of shared responsibility for a crisis in climate change given the unequal distribution of the anthropogenic origins of climate change, emblematized by the disparities in fossil fuel emissions worldwide–which most ominously ballooned from the mid-1960s to the present day.

Carbon Emissions

Despite the use of maps to localize disparities in fossil fuel emissions, map smog map smog or define localized ozone holes, no greater detail is available in maps than disparities in air quality.   As we struggle undertake to trace such disparities, it is especially striking web-based maps reveals deep discrepancies in how levels of pollution have constrained questions of habitability at local levels, already evident in the imbalances revealed in data taken from the World Health Organization of the variations in the distribution of local means of small particle matter less than 2.5 microns across the earth.

Global Particulate Matter 2:5 WHO

The challenge of translating changes in the biosphere to a static map is not easy.  Even visualizing the range of changes runs the risk of reducing or distracting the intensity of their impact.  Dipesh Chakrabarty has aptly observed how environmental change constitutes “as a geophysical force, [a situation where] we now wield a different kind of agency as well – one that takes us beyond the subject/object dichotomy, beyond all views that see the human as ontologically endowed beings, beyond questions of justice and human experience.” For the very reason that we are immersed in its changes, we are challenged to read the record of massive changes and shifts in global environment of the sort registered in a map.

But the regional distributions of variations in that manmade environments have been recently readily synthesized on a Google Maps API to provide a scary spectrum of how we alter polluted air quality in real time:  the shifts in select areas of the world–even if these areas which release pollutants that of course disperse worldwide–reveal one image of the uneven distribution of our entrance into the era of the Anthropocene. And although the ethics surrounding the degree to which over-industrialized countries have over-contributed to the advancing of markers of the dawn of the Anthropocene–from global warming to increased CO2 emissions to ocean salinity–the spectrum of the local distribution of air pollutants demands to be read.  The coding of such pollutants in the AQI keys each region by its departure from acceptable levels of health–and indeed the departure from standards of the Holocene, based on different levels or parts per million of contaminants able to lodge in the lung.

legend with promos

If the dawn of the Anthropocene presents itself as a counter-discourse to a globalized economy, raising the multiple specters of the risks and dangers of unfettered economic development and growth, it reflects inescapable constraints on those very practices and presumption of human liberties:  for it articulates “biogeochemical processes which [not only clearly] imperil the human species’ life-support system; it is also the antithesis of a politico-ontological condition central to modernity: freedom,” as Ben Dibley has observed in his Seven Theses on the Anthopocene, and articulate the parameters or constraints in which human freedom must henceforth now be re-understood–constraints in which mechanisms of the market might be able to secure and to perpetuate livable conditions of an easily habitable space.

Mapping real-time concentrations of pollutants offer snapshots of specific moments, rather than images of a geological “deep time” or defining a single tipping point of long-term ecological flows.  But the discrepancies in global air pollution registered in a real-time air quality index map charts reported measurements of airborne pollutants in a Google Maps API to trace a shifting canvas of how we are now engaged in the alteration of the environment. While misleading to some, in its claim that “Good” levels of pollution exist in many regions, the distribution raises stunning divisions in the levels of local atmospheric contamination based on air quality indices.   As of today, the map suggested particularly localized pockets of pollutants, with a surprisingly large number of sites marked red (Unhealthy; 151-200 AQI, as defined by AirNow) and violet (Very Unhealthy, 201-300 AQI), and three sites in Delhi, Finland, Austria, and Coyhaique, Chile viewed of Hazardous air quality levels of over 300, which qualifies for a health alert. This sort of mapping of the man-made environment, where discrepancies in air pollution can be readily registered, offers something of a map of anthropogenic effects.  Variations in pollutants offer blunt tools to trace the disparities of anthropogenic impact on the global atmosphere–or to register a “local” distribution of the geophysical forces of the impact of Anthropocene.

pokets of pollutants

As one scrolls across or zooms in to discern the different distribution of colored placards that dot the map’s familiarly and largely light green surface, one readily flags something like environmental divides across both large regions of the global atmosphere, as well as specific noticeable differences of place, no doubt relating to industry, and shifting standards that raise the question of whether entrance to the Anthropocene is indeed the other side of the coin of globalization, or how much local, regional, and indeed striking national differences persist in this mapping of inhaled air, clustering in individual countries’ different standards of emissions for industry or automobiles.

Mapping Air Divides

The cartographical labels in the above map tracking air-pollutants offers a new grounds for the label “Red China” by the density of its clustering of unhealthy levels of air pollution as of this May 22:

%22Red%22 China

A recent study from the researchers at  Berkeley Earth has measured the devastating effects of such levels of pollution, caused mostly by coal-burning, on China’s population, and does better by discriminating the levels of specific pollutants:  the lack of restrictions on coal-burning contributes a devastating number of deaths of 4,400 Chinese each day, totaling some 1.6 million annually, on account of the diffusion of airborne particles of less than 2.5 microns in diameter–able not only to lodge in the lungs, but be absorbed into the bloodstream, in ways that t take the notion of the Anthropocene to the level of the embodied.  Based on hourly readings at some 1,500 stations in mainland China, Taiwan and Korea, the distribution of almost entirely man-made pollutants can be tied with relative certainty to increasing rates of asthma, strokes, lung cancer, and heart attacks.  And the numbers are shocking, from the concentration of particulate matter in the particularly pungent sulfur dioxide, released by burning fossil fuels, or nitrogen dioxides, a toxic pollutant emitted from the widespread combustion of petrochemicals:

PPB China
Alarmingly high levels of pollutants greater than 2 ppb/hour.

It is no surprise that sites of industry where coal-burning is allowed offer more clearly defined sites of concentration of Sites of industry divide and readily distinguish air quality dramatically worldwide and in North America, revealing the local impact of the human on the biosphere:

The largely “green” California, whose ocean rim encourages a high quality of air, even with its own well-known pockets of pollution in its Southlands:

California Green? May 21, 3-18

Piled up green rectangles don’t all equally signify healthy air quality, one should again note, but the discrepancies from Los Angeles to Tijuana, Mexico are nice to place in relief.

Southern California Air

Given the increased amounts of small particulate matter of a radius of less than 2.5 microns in much of southern California, whose clickable feature show the somewhat overly bulky embedding of data in this world map–

PM 2.5

the proportion of this particularly pernicious pollutants to entering and lodging within human lungs can’t help but recall a current rash of uncontrolled fires searing southern California’s coastline this mid-May, themselves tied to the effects of human presence:

California Fires mid-May 2014

Such considerably broad variations in air quality force one to wander more broadly over the slippy map’s surface,  exploring ties, evoked in how Ben Dibley’s characterized the Anthropocene as newly emerging global apparatus folding global economic relations in the geographic that creates the “terrestrial infrastructure for global capital.” The arrival of an Anthropocene, Dibley clarifies, “signals a geological interval since the industrial revolution, where, through its activities, through its numbers, the human species has emerged as a geological force now altering the planet’s biosphere,” evident in the exponential growth of the human population and the arrival of new geographical strata of Anthropocene rock built to serve the needs of ever-expanding inhabitants:  concrete highways, sidewalks, parking lots, airports and landing strips, or Superfund sites of toxic waste or garbage patches and trash vortices, steel shopping centers, loading zones, or the earlier mines, garbage dumps, and railroad depots that collectively signify the remaking of the inhabited world, but whose totality comes to create parameters for future growth.  The changing global apparatus to the earth system in which the human is an agent appears the underside of a narrative of modernization, whose inescapable telos is not emancipation from natural forces or limits, but entrapment by them:  freedoms to pursue economic development become the primary threats to the support system enabling human life.  Despite difficulties in relying on Google Maps as a measure of the constraints on that freedom, the measure of atmospheric pollutants lift a corner on the increasingly circumscribed limits that actually curtail individual freedom. Its measurement is particularly compelling for what they suggest about how economic development tied to the project of modernity come to constrain the world’s continued inhabitation by human life–as the pernicious nature of the development of Abu Dhabi throws into relief.

Emirates and Abu Dhabi 5.21, 3-10

This sort of a map is predicated on the numbers on which it is based.  The variations in measurements of air quality are striking on the Canadian border, perhaps revealing different standards or sampling practices.

Europe offers interesting variations in quality of healthy air, with most danger signs located in the UK and North Sea:

%22Europe%22 in Air Pollutedness   Ireland, North Sea and Germany may 21, 3 pm

Central Europe, thought a bear of industry and coal, seems both highly monitored and at the same time roughly comparable to England:

EU Air

But the pocket of air quality that is literally off the charts one day near to Ankara–999–raises questions about how relatively low readings are in cities quite nearby.

Ankara and Turkey, May 21 3-06 pm

To be sure, Anatolia can also, in other real-time maps, seem quite green on other days:

Anatolia can also be so Green

Real-time air pollution seems egregiously under-reported in South Asia, however, despite real high readings in two concentrations that seem quite situated at first glance:

Southern Asia:india

But a slightly magnified scale reveals greater local detail in a polluted zone:

near Rajiv Gandhi Infotech Park

Even if the readings of unhealthy air quality around Pune and Mumbai, if concern for alarm, are not comparable to Ankara:

Near Mumbai   Pune--Very Unhealthy!

The accessibility of a full report of air quality of any place on a pop-up screen suggest a level of detail, to be sure, that this post does not do justice. But one is impelled to marvel at the stark inequities in the Anthropocene, both surprising and unjust, from Mexico City to Ankara or China:

Mexico City at continental divide   Ankara and Turkey, May 21 3-06 pm

The striking global inequalities of concentrations of air pollution that seem particulate endemic across China cannot, however, help but give pause for the hazardous concentrations of particulate matter that they indicate.

Chinese Cities

Despite a dangerously uniform measurement of particulate matter (AQI) verging on or surpassing 200, the concentration in Shanxi provide is particularly striking near its shore, and reaches an apex of 890 in Shangdong province, despite poor air quality of particular unhealthiness in the gulf:

Shanxi Province, pocketsin ports

The remarkably high levels of air pollutants along the Yellow River is particularly alarming and striking, since pockets of particulate matter of less than 10 microns, particularly dangerous to the respiratory system, approach hazardous levels in Shangdong (890), and even finer–and more dangerous–clusterings of much more dangerous particulate matter of diameter less than 2 microns, able to lodge more deeply in the lungs, reach hazardous levels in Bizhou.  Have the health risks been conceived?

Clusters in Binzhou   Binzhou

In the south of China, from Chengu to Hubei to Anhui provinces, one can trace a stream of red flags along rivers, and multiple regions of unhealthy air quality deep in the interior:

Chengdu to Hubei

The far better air quality in the Guangdong region, in sharp contrast, reveals concentrations of airborne pollutants outside of the port of Hong Kong.

Guangdong Province-outside Hong Kong

But what to make, on the eve of the accord between China and Russia on natural gas pipelines, of the apparent absence of limits on air pollutants in so very much of the PRC?

Mapping Air Divides

The commercial tie-in is rather obvious, and the map may be a marketing device for masks made to filter out particulate matter, in a wonderful example of cartographical product placement:
