Campus Liberty Alliance and Liberty News Network reporting from The Fourth International Conference on Climate Change which was held in Chicago, Illinois on May 16-18, 2010. The conference called attention to new scientific research on the causes and consequences of climate change, and to economic analysis of the cost and effectiveness of proposals to reduce greenhouse gas emissions. The theme of the conference was titled Reconsidering the Science and Economics. New scientific discoveries are casting doubt on how much of the warming of the twentieth century was natural and how much was man-made, and governments around the world are beginning to confront the astronomical cost of reducing emissions. Economists, meanwhile, are calculating that the cost of slowing or stopping global warming exceeds the social benefits. Rebecca Terrell, writer for The New American Magazine, gives a summary of the conference schedule and speakers.
