Avoiding a ‘Ghastly Future’ — and a few responses

“Telling the Truth,” as per Extinction Rebellion’s first rule, turns out to be a bit complicated.  It’s easy to tell the “We’re probably fucked” part of the story. The hard part is imagining a way forward.

Back in January, a group of 17 ecologists and environmental scientists — prominently including Paul Ehrlich — published Underestimating the Challenges of Avoiding a Ghastly Future in Frontiers in Conservation Science.

It’s a must read, and a grim one. And can’t hope to improve on the summary ecologist Carl Safina gave in Yale Environment 360 when he said that it reads “reads less as an argument than as a rain of asteroids encountered in the course of flying blind on a lethal trajectory,” or his summary of its findings, which only begin with biodiversity loss. Here (minus the links) is a sample:

“Major changes in the biosphere are directly linked to the growth of human systems. While the rapid loss of species and populations differs regionally in intensity, and most species have not been adequately assessed for extinction risk, certain global trends are obvious. Since the start of agriculture around 11,000 years ago, the biomass of terrestrial vegetation has been halved , with a corresponding loss of >20% of its original biodiversity, together denoting that >70% of the Earth’s land surface has been altered by Homo sapiens . There have been >700 documented vertebrate and ~600 plant species extinctions over the past 500 years, with many more species clearly having gone extinct unrecorded . Population sizes of vertebrate species that have been monitored across years have declined by an average of 68% over the last five decades, with certain population clusters in extreme decline , thus presaging the imminent extinction of their species . Overall, perhaps 1 million species are threatened with extinction in the near future out of an estimated 7–10 million eukaryotic species on the planet, with around 40% of plants alone considered endangered . Today, the global biomass of wild mammals is <25% of that estimated for the Late Pleistocene , while insects are also disappearing rapidly in many regions.”

But I’m not writing to ask you to read the “ghastly” paper. I’m writing to ask you to read it, and then to read Safina’s review of it, and then to read Notes from a 1.2C world, a response the emerging critic Laurie Laybourn-Langton wrote of it, and my own response, below, though with the stipulation that is an it’s an “insider” document I wrote to the folks at The Omega Network after attending the webinar they organized to discuss it. And I’m asking you, after doing all this reading, to up your game.

What’s the problem? That this paper, brilliant though it is in describing the deterioration of our planetary home, it is not equally brilliant when it comes to helping us work out how to respond. Which was to be expected back in the old days, but this is 2021 — the eye of the storm — and the second wind is approaching, and what matters now is what we’re going to do.

Not that Ghastly’s description of the problem is bad . . .

Just how hard is adaptation going to be?

Once up a time, people feared that “adaptation” would become a convenient excuse for avoiding mitigation. More recently, it’s become harder to believe that adaptation, taken seriously, would be anything but challenging.

Two recent reports by the New York Times have made this crystal clear:

The first, The Great Climate Migration, is nothing less than astonishing. I will not even attempt to summarize it, though I will note its comment that “In the most extreme climate scenarios, more than 30 million migrants would head toward the U.S. border over the course of the next 30 years.” And I will add the observation that this will be a challenge to both our national soul and our democracy. It’s an obvious truth, of course, but it bears repeating.

The second, How Decades of Racist Housing Policy Left Neighborhoods Sweltering, turns away from the suffering abroad, and spotlights the suffering right here at home. Again, there is no surprise, though I myself have never seen the legacy of redlining expressed as carefully mapped urban heat islands. Nor did I know just how hot those islands were.

“Across more than 100 cities, a recent study found, formerly redlined neighborhoods “are today 5 degrees hotter in summer, on average, than areas once favored for housing loans, with some cities seeing differences as large as 12 degrees. Redlined neighborhoods, which remain lower-income and more likely to have Black or Hispanic residents, consistently have far fewer trees and parks that help cool the air. They also have more paved surfaces, such as asphalt lots or nearby highways, that absorb and radiate heat.”

Read this. Then go back and reread Ta-Nehisi Coates’ classic The Case for Reparations. The implications are as painful as they are obvious.

Adaptation is not going to be cheap or easy. Nor is it just a matter of sea walls and heat pumps. It’s about facing history.
