Leading global warming deniers have wrapped up a three-day conference in New York. The slogan for the gathering was “Global Warming Is Not a Crisis.” Organizers describe it as the first major international conference to focus on issues and questions not answered by advocates of the theory of man-made global warming. The Heartland Institute organized the conference. The free-market public policy think tank received nearly $800,000 from ExxonMobil between 1998 and 2005. Board members of the Heartland Institute include Thomas Walton, director of Economic Policy at General Motors, and James Johnston, former senior economist for the oil company Amoco.
