Schelling has been involved in the global warming debate since chairing a commission for President Jimmy Carter in 1980. He believes climate change poses a serious threat to developing nations, but that the threat to the United States has been exaggerated. Drawing on his experience with the Marshall Plan after World War II, he has argued that addressing global warming is a bargaining problem; if the world is able to reduce emissions, poor countries will receive most of the benefits but rich countries will bear most of the costs.
