The Fourth International Conference on Climate Change May 15, 2010

Host: Heartland Institute. This conference calls 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. 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.
