On a Monday morning at the end of October, Rob Ross asked a group of earth scientists and educators a question: How many of them had received copies of the Heartland Institute book Why Scientists Disagree About Global Warming?
You could feel an immediate sense of frustration in the air. Roughly half of them raised their hands. The Heartland Institute is a Chicago-based think tank that rejects the scientific consensus that humans are changing the climate and has received funding from the conservative billionaire Koch brothers and fossil fuel industry.
In March, it mailed, unsolicited, a 135-page book and accompanying DVD to tens of thousands of science teachers at public high schools across the U.S., with plans to keep that up until the report was in the hands of every last one.
