Despair All Ye Who Enter Into the Climate Change Fray

A New York Magazine story on climate change is making the rounds on the internet, frequently being shared by people characterizing it as a “terrifying” “must-read.” “It is, I promise, worse than you think,” writes David Wallace-Wells, who goes on to tell his readers that even the most anxious among them are unaware of the terrors that are possible “even within the lifetime of a teenager today.”

What many readers seem to be overlooking is how frequently words like “may” appear in the text of Wallace-Wells’ article. “May” is in there seven times; “suggest” six times, “possible” and its variants a few more. Wallace-Wells is, of course, referencing the positions of scientists, whom he says have become extra cautious due to “climate denialism,” steering the public away from “speculative warnings” that could be debunked by future scientific progress, weakening their own case and giving weight to their opponents.

As Jack El-Hai wrote for Longreads in April of this year, science editor Peter Gwynne is still dogged by an article he wrote for Newsweek more than 40 years ago, “The Cooling World,” which predicted — wrongly, as it turns out — another Ice Age. The prediction was at the time supported by evidence, he claimed, was mounting so quickly. “meteorologists are hard-pressed to keep up with it.” The evidence Gwynne relied on has since been disproved — a phenomenon not uncommon a field as relatively young as climate study. As El-Hai noted:

The study of the world’s climate was still primitive in the 1970s. Few meteorological scientists then knew how to interpret trending temperature information, and the cause of climate changes was mysterious. The information that climate researchers had collected was incomplete and easy to misread. The biosciences have advanced by huge leaps since then, and many more scientists now study the climate.

Gwynne’s article was used for decades as fodder by those who trade in what Wallace-Wells dubs “climate denialisms,” showing how those determined not to believe in a certain scientific finding can benefit from the natural trial-and-error of most scientific inquiry.

After Wallace-Wells’s piece was published, climate scientist Michael E. Mann took to Facebook to criticize his story. (He also claimed Wallace-Wells interviewed but didn’t quote or mention him). Mann is equally critical of “doomist framing” and “those who understate the risks” of climate change, and argues that Wallace-Wells’ article includes “extraordinary claims” without “extraordinary evidence” to back it up.

About the risk of catastrophic methane released by melting permafrost, for example, Mann says the science “is much more nuanced and doesn’t support the notion of a game-changing, planet-melting methane bomb. It is unclear that much of this frozen methane can be readily mobilized by projected warming.”

Mann also highlights Wallace-Wells’ referencing of “satellite data showing the globe warming, since 1998, more than twice as fast as scientists had thought.”

“That’s just not true,” writes Mann. “The study in question simply showed that one particular satellite temperature dataset that had tended to show less warming that the other datasets, has now been brought in line with the other temperature data after some problems with that dataset were dealt with… The warming of the globe is pretty much progressing as models predicted… which is bad enough.”

Mann’s position is that the evidence supporting the notion that climate change is “a serious problem that we must contend with now” is overwhelming enough without a doomsday narrative that he fears has a “paralyzing” effect and makes people feel hopeless, potentially deterring efforts to mitigate the human-caused harm.

There’s an argument to be made in defense of Wallace-Wells’ meltdown-style writing, however. As Atlas Obscura staff writer Sarah Laskow noted on Twitter, the exploration on which he embarks is hardly novel — New Yorker writer Elizabeth Kolbert won a Pulitzer this year for a book on the topic, The Sixth Extinction: An Unnatural History. Yet, Wallace-Wells’ story got readers’ attention in a way that seemed to suggest it was news they’d never encountered before.

For scientists like Mann, it’s true that the evidence easily at our fingertips is compelling enough to warrant immediate mitigating efforts. But not everyone is a scientist like Mann. As El-Hai noted in his piece on Gwynne’s disproved Newsweek article, a U.S. Senator held up a snowball on the Senate floor in 2015 as part of an argument that global warming isn’t real. Today, Antarctica is poised to shed one of the largest icebergs ever recorded, while the Trump administration is abandoning international climate agreements, undoing dozens of environmental regulations dealing with everything from methane to grizzly bears to chemical spills and using the agency meant to protect the environment to launch a program challenging climate science. In light of all that, it’s just as easy to sympathize with Mann’s concern about making people feel so hopeless they believe there’s nothing left to be done, as it is hard to blame Wallace-Wells for despairing.
