Michael Shermer on Global Warming: "data trumps politics"
Michael Shermer was a well known global warming skeptic until he publicly changed his position in the June 2006 issue of Scientific American. He says: "Nevertheless, data trump politics, and a convergence of evidence from numerous sources has led me to make a cognitive switch on the subject of anthropogenic global warming. My attention was piqued on February 8 when 86 leading evangelical Christians--the last cohort I expected to get on the environmental bandwagon--issued the Evangelical Climate Initiative calling for 'national legislation requiring sufficient economy-wide reductions' in carbon emissions."
Then I attended the TED (Technology, Entertainment, Design) conference in Monterey, Calif., where former vice president Al Gore delivered the single finest summation of the evidence for global warming I have ever heard, based on the recent documentary film about his work in this area, An Inconvenient Truth. The striking before-and-after photographs showing the disappearance of glaciers around the world shocked me out of my doubting stance. [...]
Because of the complexity of the problem, environmental skepticism was once tenable. No longer. It is time to flip from skepticism to activism.
