Climate Change Policy

Begun in 1989, the Institute's program involves a critical examination of the scientific basis for global climate change policy. The intent is to promote a clear understanding of the state of climate science and assess the implications for public policy. A major component of this effort is communicating the findings to policy makers, the media and the public policy community.

For about a decade, there has been an ongoing debate about the contribution of human activities to the global warming of the past century and how they may contribute to warming that may occur during the 21st century. Too often this debate has been contentious. International efforts to reach agreement on inferences about human influence on the climate system that can be drawn from science and policy prescriptions for addressing the climate change risk have been controversial as well.

Wise, effective climate policy flows from a sound scientific foundation and a clear understanding of what science does and does not tell us about human influence and about courses of action to manage risk. Many of the temperature data and computer models used to predict climate change are themselves uncertain. Reducing these many uncertainties requires a significant shift in the way climate change research is carried out in the U.S. and elsewhere.

Are calls about the uncertainty in the state of scientific knowledge a call for no action? Nothing could be further from the truth. The message to policy makers is not to delay actions until uncertainties are reduced. Rather, actions should flow from the state of knowledge, should be related to a long-term strategy and objectives and should be capable of being adjusted ? one way or the other ? as the understanding of human influence improves. There is a sufficient basis for action because the climate change risk is real. Yet it is equally true that actions must not be predicated on speculative images of an apocalyptic vision of life in the near future.
