For the scientists who study global warming, now is the winter of their despair.
In the news, it has been climate scandal after alleged climate scandal. First came “ClimateGate,” then “GlacierGate,” “Amazon Gate,” and so on. In public opinion polls, meanwhile, Americans’ acceptance of the science of global warming appears to be declining. Even a freak snowstorm now seems to sow added doubt about this rigorous body of research.
In response to growing public skepticism—and a wave of dramatic attacks on individual researchers—the scientific community is now bucking up to more strongly defend its knowledge. Leading the charge is one of the most frequently attacked researchers of them all—Pennsylvania State University climatologist Michael Mann.
In this interview with host Chris Mooney, Mann pulls no punches. He defends the fundamental scientific consensus on climate change, and explains why those who attack it consistently miss the target. He also answers critics of his “hockey stick” study, and explains why the charges that have arisen in “ClimateGate” seem much more smoke than fire.
Dr. Michael E. Mann is a member of the Pennsylvania State University faculty, and director of the Penn State Earth System Science Center. His research focuses on the application of statistical techniques to understanding climate variability and change, and he was a Lead Author on the “Observed Climate Variability and Change” chapter of the Intergovernmental Panel on Climate Change (IPCC) Third Scientific Assessment Report. Among many other distinguished scientific activities, editorships, and awards, Mann is author of more than 120 peer-reviewed and edited publications. That includes, most famously, the 1998 study that introduced the so called “hockey stick,” a graph showing that modern temperatures appear to be much higher than anything seen in at least the last thousand years. With his colleague Lee Kump, Mann also recently authored the book Dire Predictions: Understanding Global Warming. Finally, he is one of the founders and contributors to the prominent global warming blog, RealClimate.org.
