Recently I have encountered the counterattack on climate-change science, and it is a sobering experience.
When I was giving a talk at a book store on Manhattan's Upper West Side late last month, a young man began to pester me with hostile questions. My book, 100 Ways America is Screwing Up the World, has "Altering the Earth" listed at No. 1, a chapter that briefly tours the science and politics of climate change. The young man (among other obstreperous comments) upbraided me for saying there was scientific consensus on climate change, telling the audience that he had a petition signed by 17,000 scientists denying the threat of global warming.
It was the first I had heard of such a petition, but in the days to come I noticed emails from people I'd never heard of on this same topic. The book, I knew, was bound to stir some passions, and it has. I have a dozen ecological topics listed, so anti-green zealots were bound to find me. And the main way they have attacked the book is by wielding this Global Warming Petition.
