Air Quality

The tracking of local air quality is a contemporaneous way to track the effects of the fire seige that initiated clusters of fires across the western seaboard to be ignited at the end of a long, dry summer from August 25. We were not really struck unawares by the dry lightning, but had left forests languishing, not beneath electricity lines–as last year, around this time–but under a hot sun, and high temperatures that we hardly registered as changing the ecosystem and forest floor. But we watched the real-time surveys of air quality with renewed attentiveness as an orange pyrocumulus clouds blanketed usually blue skies of the Bay Area, obscuring the sun’s light, suffusing the atmosphere with a weirdly apocalyptic muted light, that were hardly only incidental casualties of the raging fires that destroyed houses, property, and natural habitat–for they revealed the lack of sustainability of our warming global environment.

The soot and fog that permeated “clean cities” like Portland and San Francisco came as a sudden spike in relation to the black carbon loads that rose in plumes from the fires, as if the payload of the first bombs set by climate change. The shifting demand for information that evolved as we sought better bearings in the new maps of fires that had become a clearly undeniably part of our landscape was reflected in the skill with which the sites of incidence of dry lighting strikes that hit dried out brush and forest floors, the growing perimiters of fires and evacuation zones across the west coast, and the plumes of atmospheric smoke of black carbon that would leave a permanent trace upon the land, liked to the after-effects of holocausts created by atom bombs by Mike Davis. The measurement of wind carrying airborne smoke emerged as a layer of meaning we were beginning to grasp, a ghostly after-effects of the fields of flams that began from sites of lightning hitting the earth in a Mapbox wildfire map of fields of fire across the states, radiating resonant waves akin to earthquake aftershocks, a lamination on hex bins of the fires that seemed a new aspect indicating their presence in the anthropocene.

The suitably charcoal grey base-map of the state integrates approximate origins of fires, fire spread and greatest intensity of hotspots from satellite imagery courtesy Descartes Labs and NOAA, and air pollution data integrates the fires’ spread across our picture of the state. While human reviewed and sourced, the satellite data embodies the ravages of fire across the state in ways echoed by its black charcoal base map, and reflects the need to develop new visual tools to process their devastation.

While we began to measure air quality to meet new needs to track ground-level ozone, acid rain, air toxins, and ozone depletion at an atmospheric level, the increased tracking of more common air pollutants since 1990 included airborne particulate matter (PM10 and PM2.5), carbon monoxide (CO), and ozone (O3), we track the effects of wildfire smoke by hourly levels of each at local points, parlaying sensors into newsfeeds as wildfires rage. If stocked with labels of each chromatic layer, are these real-time updates lacking not only legends–but the temporal graph that would clarify the shifting data feeds that lead us to give them the illusion of purchase on the lay of the land we are trying to acknowledge this fire season?

Watching slightly more long-term shifts in quality of air that we breath in the Bay Area, we can see striking spikes of a maximum just after the lighting siege began on August 19, 2020 across much of the state, as air quality decisively entered into a hazardous zone, tracking PPM2.5 concentrations, but entering the worst fifteen air days since registration four times since 1999, when Bay Area Air Quality Management District began reporting the levels of fire smoke in inhabited areas.

We measure fires by acreage, but the sudden spikes of air quality, while not exceeding the smoke that funneled into the Bay Area during the North Bay Fires in 2017, when the Tubbs and Atlas Fires devastated much of the Wine Country, created a run of high-smoke days, were followed by a set of sudden spikes of the atmospheric presence of particulate matter that we tried to track by isochomes, based on real-time sensor reading, but that emerge in better clarity only in retrospect.

It is true that while the AQI maps that offer snapshots of crisp clarity of unhealthy air might serve as an alarm to close windows, remain indoors, and call off school–

–as particulate matter spread across the region’s atmosphere. We are used to weather maps and microclimates in the Bay Area, but the real-time map of particulate matter, we immediately feared, did not only describe a condition that would quickly change but marked the start of a fire season.

Not only in recent days did the sustained levels of bad air suggest an apocalyptic layer that blanketed out the sun and sky, that made one feel like one was indeed living on another planet where the sun was masked–a sense heightened by the red suns, piercing through grey smoke-cover that had seamlessly combined with fog. Although the new landscapes of these AQI maps generate immediate existential panic, we should be more panicked that while we call these fires wild, they release unprecedented levels of toxins once imagined to be detected as industrial pollutants. The seemingly sudden ways that black carbon soot blanketed the Bay Area, resting on our car hoods, porches, windowsills and garbage bins were not only an instant record of climate emergency, but the recoil of overly dry woods, parched forests and lands as overdue payback for a far drier than normal winter, months and a contracted rainy season that had long ago pushed the entire state into record territory. The lack of soil moisture has brought a huge increase of wildfire risk, not easily following the maps of previous fire history, and persistence of “abnormally dry” conditions across a third of California, focussed in the Sierra and Central Valley–the areas whose forests’ fuel loads arrive carbonized in particulate form.

Local monitors of air quality suggest the uneven nature of these actual isochromes as maps–they are reconstructions of what can only be sensed locally, and does not exist in any tangible way we can perceive–but presented what we needed to see in a tiler that made differences popped, highlighting what mattered, in ways that left cities fall into the bottom of the new colors that blanketed the state, in which local sensors somehow revealed what really mattered on August 20: if the “map” is only a snapshot of one moment, it showed the state awash in ozone and PPM.

We were in a sort of existential unfolding in relation to these maps, even if we could also read them as reminders of what might be called “deep history”: deep history was introduced by Annalistes to trace climatic shifts, the deep “undersea” shifts of time, on which events lie as flotsam, moved by their deep currents that ripple across the economy in agrarian societies, suggesting changes from which modern society is in some sense free. “Deep History” has to some extent been reborn via neurosciences, as a history of the evolution of the mind, and of cognition, in a sort of master-narrative of the changes of human cognition and perception that makes much else seem epiphenomenal. If the below real-time map was time-stamped, it suggested a deep history of climate of a more specific variety: it was a map of one moment, but was perched atop a year of parched forests, lack of groundwater, and increased surface temperatures across the west: Sacramento had not received rain since February in an extremely dry winter; its inter was 46% drier than normal, and the winder in Fresno was 45% dryer in February. They are, in other words, both real-time and deep maps, and demand that we toggle between these maps as the true “layers” of ecological map on which we might gain purchase.

The levels of dessication of course didn’t follow clear boundaries we trace on maps. But at some existential level, these flows of particulate matter were not only snapshots but presented the culmination and confirmation of deep trends. We have to grasp these trends, to position ourselves in an adequate relation to their content. For the deep picture was grim: most of California had enjoyed barely half of usual precipitation levels after a very dry winter: Sacramento has had barely half of usual rainfall as of August 20 (51%); the Bay Area. 51%; parts of the Sierra, just 24%. And wen we measure smoke, we see the consequences of persistent aridity.

These are the layers, however, that the maps should make visible, And while these shifts of particulate matter that arrived in the Bay Area were invisible to most, they were not imperceivable; however, the waves of smoke that arrived with a local visibility that was oppressive as they blanketed out the sun. Perhaps there was greater tolerance earlier, tantamount to an ecclipse. Perhaps that seemed almost a breaking point.

For almost a month after the first fires broke, following a sequence of bad air days and spare-the-air alerts marked our collective entrance to a new era of climate and fire seasons, fine soot blanketed the state at hazardous levels, leaving the sense there was nowhere left to go to escape.

We had of course entered the “Very Unhealthy” zone. If real-time maps condense an immense amount of information, the snapshot like fashion in which they synthesized local readings are somewhat hard to process, unless one reads them with something like a circumscribed objective historical perspective that the levels of PPM5 provides. In maps that are data maps, and not land maps, we need a new legend, as it were, an explanation of the data that is being tracked, lest it be overwhelmed in colors, and muddy the issues, and also a table that will put information on the table, lest the map layers be reduced to eye candy of shock value, and we are left to struggle with the inability to process the new scale of fires, so unprecedented and so different from the past, as we try to gain bearings on our relation to them.

Of course, the real-time manner that we consume the “news” today militates against that, with feeds dominating over context, and fire maps resembling increasingly weather maps, as if to suggest we all have the skills to read them and they present the most pressing reality of the moment. But while weather maps suggest a record of the present, these are not only of the current moment that they register. Looking at them with regularity, one feels the loss of a lack of incorporating the data trends they depict, and that are really the basis of the point-based maps that we are processed for us to meet the demand for information at the moment, we are stunned at the images’ commanding power of attention to make us look at their fluid bounds, but leave us at sea in regards to our relation to what is traced by the contour lines of those isochrones.

We can, in the Bay Area, finally breathe. But the larger point re: data visualizations is, perhaps, a symptom of our inflow of newsfeeds, and lies in those very tracking maps–and apps–that focus on foregrounding trends, and does so to the exclusion of deeper trends that underly them, and that–despite all our knowledge otherwise–threatens to take our eyes off of them. When the FOX newscaster Tucker Carlson cunningly elided the spread of wild fires ties to macro-process of climate change, calling them “liberal talking points,” separate from climate change, resonating with recent calls for social justice movements to end systematic racism in the country: although “you can’t see it, but rest assured, its everywhere, it’s deadly. . . . and it’s your fault,” in which climate change morphed to but a “partisan talking point” as akin to “systematic racism in the sky.”

While the deep nature of the underlying mechanics by which climate change has prepared for a drier and more combustable terrain in California is hard to map onto to the spread of fires on satellite maps, When climate denialism is twinned with calls for reparations of social injustice or gun control as self-serving narratives to pursue agendas of greater governmental controls to circumscribe liberties, befitting a rant of nationalist rage: the explanations on “our” lifestyles and increased carbon emissions, only pretenses to restrict choices we are entitled to make, Carlson was right about the depths at which both climate change and systematic racism lie, especially if we squint at tracking maps at a remove from deep histories, and cast them as concealing sinister political interests and agendas, the truly dark forces of the sinister aims of governmental over-reach in local affairs. “Structural racism” is indeed akin to the deep structure of climate change, evident in the maps of trends of diminished precipitation, groundwater reserves or temperature change that are all too often obscured by the events of local air quality or maps of social protests that respond to deep lying trends. To be sure, the tracking of environmental pollutants underlay the national Pollution Prevention Act of 1990, and led to a number of executive orders that were aimed to set standards for environmental justice among minority communities who long bore the brunt of industrial pollutants, from lead paint to polluted waters to hazardous waste incinerators.

But if the AQI maps tell us anything, it is the lack of preparedness for the increasing connections in this new climate of fire, smoke, and large dry stretches of a long story of low precipitation that have created abnormally dry conditions–indeed, drought–across the state.

Earth, Wind, and Fire

We think of earth, wind and fire as elements. Or we used to. For the possibility of separating them is called into question in the Bay Area, as wind sweeps the smoke of five to seven fires, or fire complexes, across the skies, we are increasingly likely to see them as layers, which interact in a puzzle we have trouble figuring out. Indeed, the weirdly haunting
map of air quality to map the atmospheric presence of particulate matter by isochrones brought late summer blues to the Bay Area.

Fire season began by remapping the town in terrifying red that registered “unhealthful,” but almost verging on the “hazardous” level of brown, based on local sensors monitoring of ozone, but is also registering a deeper history defined by an absence of rain, the lack of groundwater, the hotter temperatures of the region and the dry air. The map is both existential, and ephemeral, but also the substrate of deep climate trends.

AQI Chart on Saturday, August 22, 2020/AirNow (EPA)

Is fire an element we had never before tracked so attentively in maps? We did not think it could travel, or had feet. But wildfire smoke had blanketed the region, in ways that were not nearly as visible as it would be, but that the real-time map registers at the sort of pace we have become accustomed in real-time fire maps that we consult with regularity to track the containment and perimeters of fires that are now spreading faster and faster than they ever have in previous years. And soon after we worried increasingly about risks of airborne transmission of COVID-19, this fire season the intensity of particulate pollutants in the atmosphere contributed intense panic to the tangibility of mapping the pyrocumulus plumes that made their way over the Bay Area in late August. As the danger of droplets four micrometers in diameter remaining airborne seemed a factor of large-scale clusters, the waves of black carbon mapped in the Bay Area became a second sort of airborne pathogen made acutely material in layers of real-time Air Quality charts.

The boundaries of fire risk charts and indeed fire perimeters seemed suddenly far more fluid than we had been accustomed. When we make our fire maps with clear edges, however, it is striking that almost we stop registering the built environment, or inhabited world. As if by the magic of cartographical selectivity, we bracket the city–the sprawling agglomeration of the Bay Area–from the maps tracking the destructiveness and progress we call advancing wildfires, and from the isochronal variations of air quality that we can watch reflecting wind patterns and air movements in accelerated animated maps, showing the bad air that migrates and pool over the area I life. The even more ephemeral nature of these maps–they record but one instant, but are outdated as they are produced, in ways that fit the ecoystem of the Internet if also the extremes of the new ecosystem of global warming–the isochrones seem somewhat fatalistic, as they are both removed from human agency–as we found out in the weeks after the Lightning Siege of 2020–if they are the result of the extra urban expansion that has pushed houses to the borders of forests we haven’t ever faced the problem of maintaining and clearing in weather this dry: as a result, we are now burning underbrush that has lain like kindling, on the boundaries of the raging fire complexes, hoping to create fire lines and new perimeters able to forestall the advance of major fires, even as the smoke escapes from them and travels across the nation, far beyond the Bay Area.

While watching the movement of fires that them in inhabited areas like shifting jigsaw pieces that destroy the landscape across which they move. These marked the start of megafires, that spread across state boundaries and counties, but tried to be parsed by state authorities and jurisdictions, even if, as Jay Inslee noted, this is a multi-state crisis of climate change that has rendered the forests as fuel by 2017–for combined drought and higher temperatures set “bombs, waiting to go off” in our forests, in ways unable to be measured by fire risk that continues to be assessed in pointillist terms by “fuel load” and past history of fires known as the “fire rotation frequency.” When these bombs go off, it is hard to say what state boundary lines mean.

Fire Threat Risk Assessment Map, 2007

If San Francisco famously lies close to natural beauty, the Bay Area, where I live, lies amidst of a high risk zone, where daily updates on fire risk is displayed prominent and with regularity in all regional parks. These maps made over a decade ago setfire standards for building construction in a time of massive extra-urban expansion. But risk has recently been something we struggled to calculate as we followed the real-time updates of the spread of fires, smoke, and ash on tenterhooks and with readiness and high sense of contingency, anxiety already elevated by rates of coronaviurs that depended on good numbers: fire risk was seen as an objective calculation fifteen years ago, but was now not easy to determine or two rank so crisply by three different shades.

Fire Risk Map, 2007

When thunderstorms from mid-August brought the meteorological curiosity of nearly 12,000 dry lightening dry strikes from mid to late August 2020, they hit desiccated forests with a shock. The strikes became as siege as they set over three hundred and fifty-seven fires across the state, that rapidly were communicated into expansive “complexes” of brush fires.

We map these fires by state jurisdictions, and have cast them as such in policy, by borders or the perimeters we hope to contain barely grasp the consequences of how three quarters of a million acres burned up suddenly, and smoke from the cluster of fires rose in columns that spread across state boundary lines as far as Nebraska, and how fire complexes that spread across three million acres that would soon create a layer of soot across the west, eerily materialized in layers of GIS ESRI maps of environmental pollutants, while toxic particulate mater released in plumes of black carbon by the fires cover the state, rendering the sun opaque where I live, in the Bay Area, now Pompeii by the Bay as smoke at toxic levels blanketed much of the state.

They even more serious map, to be sure, was of fire spread: but the maps of air quality set the entire western seaboard apart from the nation, as if threatening to have it fall into the ocean and split off from the United States,–even if the burning of its open lands was more of a portent of things to come, they were a historical anomaly, lying outside the record of fire burns or air quality, if the poor air quality traced the origin of black carbon columns of smoke that would rise into the nation’s atmosphere.

Loopy Maps to Rationalize Random Shut-Offs?

The announcement in California of the arrival of random power shut-offs this fire season sent everyone scrambling to maps. In order to stop fires spread of fires, the impending public safety power shut-offs crashed websites as folks scrambled to get updates in real time, frustrated by the relative opacity of maps in a hub of high tech mapping and public data, as the impending possibility of power shut-offs wreaked neurological chaos on peoples’ bearings. From mapping fires, we transitioned to the uncertainty of mapping regions where consumers would lose power in an attempt to prevent fires from spreading due to strikes on live wires of broken limbs, branches, or failed transmission structures whose immanent collapse were feared to trigger apocalyptic fires of the scale of those witnessed last fires season, as the largest fire in California history raged for days, destroying property and flattening towns, burning victims who followed GPS lacking real-time information about fires’ spread.

In an eery mirroring of looking to maps to monitor the real-time spread of fires, which we sensed in much of California by smoke’s acrid air, the expectancies to which we had been habituated to consult real-time updates was transferred to the availability of electricity, in a sort of mirror image unsurprising as the outages were intended to stop fires’ spread. The decision to continue public power safety shut-offs as a part of the new landscape of controlling fires’ spread in future years–perhaps needs to be accepted for up to a decade, although this was walked back to but five years in recent years.

Expanded power shut-offs justified by needs for public safety suggest how much climate change has changed the expanded nature of fire risk. But in an era when the vast majority of televised segments that aired on network television– ABC, CBS, and NBC combined–despite an abundance of powerful image and video footage the 243 segments on destructive wildfires raging across northern and southern California, a type of public disinformation seems to have been practiced by most news outlets that served only to disorient viewers from gaining any purchase on the fires, colored by the shifting validity of climate change denial as a position among their viewing public: only eight of the news media mentions of the fires, or 3.3%, mentioned climate change as a factor in the fires’s spread, from October 21 to November 1, as the spread of fires in northern California grew that precipitated public power shut-offs. If new cycles shy away from citing climate change as a factor on the spread of fires, most of the mentions came from specific weather reporters, from NBC’s Al Roker to CBS’ Jeff Berardelli, extending the range of fire seasons and area of burn, the silo-ization of such explanations were rarely digested in mainline reporting. And if FOX ran 179 segments on the fires, more than other cable networks, climate change was mentioned in 1.7%, with most segments mocking the contribution of climate change.

If we are poorly served by the news media in reporting the fires and downplaying climate change–or indeed criticizing California for poorly maintaining its forests’ safety, as President Trump, the eery landscapes provided by PG&E raise questions about the messages they communicate.

But the electric green maps of a startlingly unnatural aquamarine, yellow, and orange suggested a strange distantiation of the landscape in the age of Climate Change. The electrified hues of the maps, which monitored the possibility of customers loosing electricity in many districts, reveals a level of poor management and lack of any coherent strategy for climate change as much as the huge area that is served by PG&E, and the man-made infrastructure of electricity and transmission towers, which courts have rightly decided the privately-owned power agency that serves state residents is responsible for.

While we follow the news, even among the most die-hard news addicts, the prospect of “public safety” power shut-offs seemed unannounced and irresponsible, and a premonition of a new landscape of risk. For the shut-offs that were announced as impending by PG&E reflect a deep insecurity of fires, climate change and perhaps what we feared was a collective unpreparedness to deal with a new set of implications of climate crisis we have not even been able to acknowledge or even fully recognize, but which seemed spinning out of control–even in the nature of maps that were made of it–and to betray a lack of imagination, creativity, and foresight, abandoning the long-term view.

The sense of emergency electrifies a landscape whose woodland-urban interface is electrified by aging power structures and transmission lines, carrying increased current to extra-urban areas. And there is a fear that the long-term view is lacking, as we continue to turn to maps, even months after the first shut-offs were announced to forestall fears of a raging fire season. As we map the expanding sense of risk to respond to both demand for currently updated real-time maps for fires, and the calamitous images of apocalyptic fires raging that dominate the news cycle and make us fear the near future, or have a sense of living with a deferred sense of emergency at our doorsteps. And so when we received a text message of impending loss of electricity, we turned en masse to maps to learn about outages at risk, alerted to the need to ready ourselves as best we could by our local government-

Extreme fire prevention funding, precarious in the Trump Era, stands to be abolished as the Dept. of Interior retreats from federal fire programs: the Wildland Fire Office, funded at $13 million in 2012, if slated to be abolished in the Trump era, in an agenda denying climate change, lacks funding, undermining close scientific examination of a new topography of fires, even as climate change has increased the costliness of fires and the ferocity of their spreads. If the costs of the Camp Fire of 2018 grow beyond $10 billion–or over six times as much as the Oakland Firestorm of 1991–those costs and the cost of insurance liabilities only stand to grow. As we confront poor planning of climate readiness, as we lack real images of extinguishing fires’ spread–and imagine the temporary shut offs can intervene as a deus ex machine to prevent fires’ spreads all we have to forestall the fears of spreading flames and intense firestorms or whirls.

In the Bay Area, where I live, the danger of the new firescape is so pressing, and so impossible to process, that we can only digest it as a danger that is ever-present, akin to living in an active seismic area, but we cannot process in a static or dynamic map.

But this is an area of risk that we are living cheek-by-jowl beside in ways that are truly unfathomable. As the power shut-off zones have been expanded in clearer detail by PG&E in response to the growing gustiness of winds that threaten to compromise the safety of residents as well as the aging electric infrastructure of the state, we are oddly haunted by past promises to maintain or upgrade our national infrastructure–the promise to rebuild national infrastructure was itself an energizing call of the Trump campaign–only to be demoted by being assigned, with improved veteran care, the opioid addiction, workforce retraining, and the Middle East peace to Jared Kushner, in ways tantamount to moving it to the way back burner, soon after being mentioned in the State of the Union as a non-partisan issue in January, 2018.

And yet, the spread of fires with increased rapidity, across landscapes that remain highly flammable, has created terrifying imagers of a highly combustible landscapes, where the recent growth of fires–in this case, the Kincade Fire that did began only long after the shut-off policies began–chart the spread of fires across terrain multiple times larger than cities, moving across the landscape rapidly, driven by unprecedentedly strong offshore winds: the passing overhead of satellites charts its expansion, making us fear the expansion of the next pass overhead as realtime images of the durations of fires only grows.

Burrito Justice/VIIRS/MODIS fire spread map/October 27, 2019

Sure, the current landscape had long seemed to be burning up at a rate we had not begun to adequately acknowledge–as Peter Aldhous promptly reminded any of us who needed reminding in Buzzfeed, providing a GIF of CalFire’s data of areas of California that had burned since the 1950s, decade by decade, in an animation of red bursts of flames atop a black map, that seemed to eerily illuminate the state by the 2000s, and hit much of the north by the 2010s, as they close,–illuminating fires as a state-localized crisis–

Peter Aldhous for Buzzfeed from Cal Fire and frap.fire.ca.gov

but the scope of human-caused fires that have consumed land, property, and habitat are a truly endemic crisis in California, he showed, in ways that he suggested reflect a parched landscape and the uptick of human-generated fires that are a direct consequence of climate change, especially in a region of increased residential construction. This sense of illumination places a huge onus on PG&E for its corporate responsibility, and the very notion of distributing electricity and power as we once did,–and illuminates the imperative to think about a new form of energy grid.

Human-Generated Fires Peter Aldhous/Buzzfeed

Indeed, the parsing of “human-caused fires” as a bucket suggests the real need to expand the classification of wildfires. Whereas most earlier fires were caused by lightening strikes in the western states, the expansion of housing and electricity into areas suffering from massive drought–as if in an eery reflection of the spread of “slash fires” across the midwest during the expansion of railroads that caused a rage if firestorms coinciding with World War I–press against the category of fires as wild. The deeper question that these maps provoke–as do the data of Cal Fire–is whether the term wildfires is appropriate to discuss the hugely increased risk of fires that damage or destroy property and land.
