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.

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.

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–





–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.
