I’m not going to waste any more time showing why climate change deniers are wrong; I believe we should ignore them and put all our efforts into pressuring President Obama and Congress to take the lead on climate change, which means beginning to reverse the flow of carbon that is warming the planet and causing the oceans to acidify. This post on DeSmogBlog.com ought to be the final word on denialism; after reading it, no one should believe there is serious disagreement in the scientific community about the reality of human-caused global warming. Post author James Powell writes, “If there is disagreement among scientists, based not on opinion but on hard evidence, it will be found in the peer-reviewed literature.” And so he surveyed the scientific literature over a 20-year period, distilling his results in “Why Climate Deniers Have No Scientific Credibility – In One Pie Chart.” The proof is in the pie chart: of nearly 14,000 peer-reviewed articles on climate in science journals in the two decades since 1991, only 24 reject global warming and they are rarely cited. Powell writes, “Of one thing we can be certain: had any of these articles presented the magic bullet that falsifies human-caused global warming, that article would be on its way to becoming one of the most-cited in the history of science.”
Of course deniers won’t be convinced by this evidence; but it ought to persuade those snowed by the blizzard of propaganda–including some mainstream journalists–that they need not give deniers equal time. As Powell says, “Only one conclusion is possible: Within science, global warming denial has virtually no influence. Its influence is instead on a misguided media, politicians all-too-willing to deny science for their own gain, and a gullible public.” If you find yourself in conversation with a gullible member of that public–a doubter rather than a full-blown denier–send her or him this article to read. Or go to the Skeptical Science site, which rebuts in a very organized way the many pseudoscientific claims made by deniers and compiles the many articles providing evidence that humans are causing global warming. Try out some of the rebuttals; make them your own. There are even smart-phone apps that lay out rebuttals to all the skeptic arguments to have in your hand when needed! Links here.
