In early January, Slate columnist Eric Holthaus tweeted: “I’m starting my 11th year working on climate change, including the last 4 in daily journalism. Today I went to see a counselor about it.” Holthaus announced that he was in “despair” over climate-change inaction: “There are days where I literally can’t work. I’ll read a story & shut down for rest of the day. Not much helps besides exercise & time.” His job, he says, is “chronicling planetary suicide.”
Holthaus’s tweets, and the massive online group-therapy session that followed, would be amusing were they not so pitiful. Here is the emotional toll of buying into one of our most saleable beliefs at present: that the planet faces imminent destruction as a result of anthropogenic climate change, rescue from which is being held up by greedy midwestern oilmen, the political operatives in their pocket, and obnoxious Republican uncles swallowed up in ignorance.
There is an extensive literature in this new millenarianism, the latest contribution to which is Michael E. Mann and Tom Toles’s The Madhouse Effect: How Climate Change Denial Is Threatening Our Planet, Destroying Our Politics, and Driving Us Crazy. Mann, as National Review readers may know, is the creator of the much-ballyhooed “hockey stick” climate graph, which purports to show an unprecedented, precipitous warming of the climate beginning in 1920; he is also currently suing National Review for having the audacity to question his findings. Tom Toles is a cartoonist for the Washington Post, whose contribution to the book is several dozen smug, self-congratulatory drawings mocking Republicans as avaricious, oblivious, and/or simply stupid.
Readers familiar with climate-change zealotry will find recognizable sound bites here: “The warming of the planet caused by our profligate burning of fossil fuels poses perhaps the greatest challenge that human civilization has yet faced. . . . If we continue with the course we are on, our destiny may indeed be to leave behind an unlivable planet of destroyed ecosystems and continuous, unpredictable chaos.” One short chapter gives an overview of the “overwhelming” scientific evidence for anthropogenic climate change, another chapter elaborates the threat — “Be it national security, food, water, land, the economy, or health . . . the specter of climate change is upon us” — and then Mann gets to his real purpose: scolding anyone who thinks differently from Michael Mann.
That there are varying degrees of skepticism toward the large set of questions that constitute the climate-change debate, or that different people partake of different motives, seems not to have occurred to Mann. Skeptics are “deniers,” and “deniers” are obviously on the payroll of fossil-fuel companies or their shadowy network of supporters. (The Koch brothers, who are apparently funding the entire Republican party, should be paying Mann as well, given the space they’re occupying in his head.) Scientists, by contrast, are just humble servants of the truth, and anyone who suggests that there might be perverse incentives operating in the scientific community simply does not know how scientific scholarship works. There is “a roughly 97 to 99 percent agreement among scientists that climate change is real and caused by humans.”
That familiar statistic, trotted out regularly by the Obama White House to bolster its climate agenda, is based on a convenient sampling of the relevant literature. In fact, there is a vigorous, vocal minority of dissenters from the climate-change consensus within the scientific community, the vast majority of whom have nothing to do with ExxonMobil. And it’s not as if there are no reasons to exercise caution. Environmental forecasts have been wildly wrong going back half a century. In 1970, Life magazine reported growing evidence that “by 1985 air pollution will have reduced the amount of sunlight reaching Earth by one half.” That same year, ecologist Kenneth Watt told an audience at Swarthmore College that, “if present trends continue, the world will be about four degrees colder for the global mean temperature in 1990, but eleven degrees colder in the year 2000. This is about twice what it would take to put us into an ice age.” NASA scientist James Hansen, an early advocate for climate-change action whom Mann cites approvingly, testified before the Senate Environment and Public Works Committee in 1986 that, “in 20 years, the global warming should reach about 1 degree Celsius, which would be the warmest the Earth has been in the last 100,000 years.” (It increased by about 0.38 degrees Celsius.)
Seeing oneself as a visionary repelling a global threat does not lead to politics as much as to fanaticism.
