Cooling Down the Cassandras
In this headline on a New York Times story about the difficulties confronting people alarmed about global warming, note the word "plateau." It dismisses the unpleasant -- to some people -- fact that global warming is maddeningly (to the same people) slow to vindicate their apocalyptic warnings about it.

The "difficulty" -- the "intricate challenge," the Times says -- is "building momentum" for carbon reduction "when global temperatures have been relatively stable for a decade and may even drop in the next few years." That was in the Times's first paragraph.

In the fifth paragraph, a "few years" became "the next decade or so," according to Mojib Latif, a German "prize-winning climate and ocean scientist" who campaigns constantly to promote policies combating global warming. Actually, Latif has said he anticipates "maybe even two" decades in which temperatures cool. But stay with the Times's "decade or so." By asserting that the absence of significant warming since 1998 is a mere "plateau," not warming's apogee, the Times assures readers who are alarmed about climate change that the paper knows the future and that warming will continue: Do not despair, bad news will resume. ...

...The Times says "a short-term trend gives ammunition to skeptics of climate change." Actually, what makes skeptics skeptical is the accumulating evidence that theories predicting catastrophe from man-made climate change are impervious to evidence. The theories are unfalsifiable, at least in the "short run." And the "short run" is defined as however many decades must pass until the evidence begins to fit the hypotheses. ...

...Warnings about cataclysmic warming increase in stridency as evidence of warming becomes more elusive. A recent report from the United Nations Environment Program predicts an enormous 6.3 degrees Fahrenheit increase by the end of the century even if nations fulfill their most ambitious pledges concerning reduction of carbon emissions. The U.S. goal is an 80 percent reduction by 2050. But Steven Hayward of the American Enterprise Institute says that would require reducing greenhouse gas emissions to the 1910 level. On a per capita basis, it would mean emissions approximately equal to those in 1875. ...
