EcoWorld: How would you say that current conventional wisdom regarding climate change has gotten it wrong?
Pielke: In terms of climate change and variability on the regional and local scale, the Intergovernmental Panel on Climate Change (IPCC) reports, the Climate Change Science Program (CCSP) report on surface and tropospheric temperature trends, and the U.S. National Assessment [of Climate Change] have overstated the role of the radiative effect of the anthropogenic increase of carbon dioxide (CO2) in relation to a diversity of other human climate- forcing mechanisms. Indeed, many research studies incorrectly oversimplify climate change by characterizing it as being dominated by the radiative effect of human-added CO2. But while prudence suggests that we work to minimize our disturbance of the climate system (since we don’t fully understand it), by focusing on just one subset of forcing mechanisms, we end up seriously misleading policymakers as to the most effective way of dealing with our social and environmental vulnerability in the context of the entire spectrum of environmental risks and other threats we face today.

Roger Pielke Sr. is a retired professor of atmospheric science at Colorado State University, Ft. Collins, and a senior research scientist at the University of Colorado, Boulder. Since July 2005 he has written and maintained Climate Science, a blog that serves as a scientific forum for dialogue and commentary on climate issues. With William R. Cotton, he is the co-author of Human Impacts on Weather and Climate (Cambridge University Press, 2007).
