CRED: A New Model of Climate and Development


The climate policy debate has largely shifted from science to economics.  There is a well-developed consensus, at least in broad outlines, about the physical science of climate change and its likely implications.  That consensus is embodied in massive general circulation models (GCMs) that provide detailed projections of average temperatures, precipitation, weather patterns, and sea-level rise.

Even the best models of physical processes, however, cannot answer the key questions about climate economics that are becoming increasingly central to policy debate: How much will it cost to stabilize the climate and avoid dangerous climate change?  How should the costs be shared?  Does climate protection promote or compete with economic development for lower-income countries?
