Choosing a Greenhouse Gas Limit: A Multisectoral Analysis    

Science, economics, and individual and societal values all have a role to play in determining the concentration level, or maximum rate of change, of atmospheric greenhouse gases that is judged dangerous. It is not a question that can be answered through the efforts of science alone. Certainly, decision makers require the best understanding of potential impacts that science can offer, but scientists also need the insights of decision makers. This research project will address the gap between what is available and what is needed if policymakers are to make sound decisions that safeguard our nation’s, and the world’s, well-being. A panel of  decision makers from industry, environmental groups, and government will help define the types and characteristics of impacts that are of greatest concern and clarify the magnitude and extent of impacts deemed unacceptable. At the same time, a multisectoral committee of leaders in climate science, economics, risk analysis, and policy from academia, industry, government, and the environmental community will analyze what is known about the relationship between the concentration and rate of increase of greenhouse gases and the impacts of concern. The effort will produce at least two reports. The first will synthesize the results of the study for decision makers, and the second, intended for the research community, will focus on theimplications for the global change research agenda.
