Ray Bradley is Director of the Climate System Research Center (www.paleoclimate.org) at the University of Massachusetts, Amherst and a University Distinguished Professor in the Department of Geosciences. His interests are in climate variability and why climate changes, over a wide range of timescales. He did his graduate work at the Institute of Arctic and Alpine Research, University of Colorado, Boulder. He has written or edited ten books on climatic change, and authored more than 100 refereed articles on the subject. In 2004, he received a Doctor of Science (D.Sc) degree from Southampton University (U.K.) for his contributions to the field of paleoclimatology.

Ray Bradley has been an advisor to various government and international agencies, including the U.S., Swiss, Swedish, and U.K. National Science Foundations, the National Oceanic and Atmospheric Administration (NOAA), the U.S. National Research Council, the Inter-Governmental Panel on Climate Change (IPCC), the US-Russia Working Group on Environmental Protection, and the International Geosphere-Biosphere Program (IGBP), Stockholm.

When I joined RC, I was a climate modeller with the British Antarctic Survey. Now I’m a software engineer for CSR. I’m still interested in communicating the science of climate change, but can no longer do so at a professional level.

I’m also elsewhere: the wikipedia project is developing into a useful resource, and my profile is User:William_M._Connolley. My personal vanity site is at www.wmconnolley.org.uk.

One of the people in the picture is me. Guess which.

ps: all my contributions online are released under the GFDL, unless I explicitly note otherwise.

A physicist and oceanographer by training, Stefan Rahmstorf has moved from early work in general relativity theory to working on climate issues.

He has done research at the New Zealand Oceanographic Institute, at the Institute of Marine Science in Kiel and since 1996 at the Potsdam Institute for Climate Impact Research in Germany (in Potsdam near Berlin).

His work focuses on the role of ocean currents in climate change, past and present.

In 1999 Rahmstorf was awarded the $ 1 million Centennial Fellowship Award of the US-based James S. McDonnell foundation.

Since 2000 he teaches physics of the oceans as a professor at Potsdam University.

Rahmstorf is a member of the Advisory Council on Global Change of the German government and of the Academia Europaea. He is a lead author of the paleoclimate chapter of the 4th assessment report of the IPCC.

Jim Bouldin is a Research Ecologist in the Department of Plant Sciences at the University of California at Davis, holding a BS in Wildlife Management from Ohio State University and a PhD in Plant Science from UCD. His primary research background/interest relates to forest change in response to human activity over the last ~ 200 years, and associated vegetation analysis methods issues, focusing on North America. If he knows anything about climate at all (pretty dubious), it is in the analysis of tree rings as climatic proxies, and the role of forest vegetation in the carbon cycle and larger climate system. He is currently working on a method for improved signal:noise ratio in the detrending step of tree ring analysis that might prove helpful, but don’t look for his name in Science, Nature or PNAS anytime soon.

Recently, trying to learn the R programming language has considerably intensified a growing tendency toward insanity, and he thinks he will likely soon be spending much more time in the mountains looking at trees and rivers and other neat stuff that needs a good looking over.

There is a bit more detail about his interests and work at his webpage.

Eric Steig is an isotope geochemist at the University of Washington in Seattle. His primary research interest is use of ice core records to document climate variability in the past. He also works on the geological history of ice sheets, on ice sheet dynamics, on statistical climate analysis, and on atmospheric chemistry.

He received a BA from Hampshire College at Amherst, MA, and M.S. and PhDs in Geological Sciences at the University of Washington, and was a DOE Global Change Graduate fellow. He was on the research faculty at the University of Colorado and taught at the University of Pennsylvania prior to returning to the University of Washington 2001. He has served on the national steering committees for the Ice Core Working Group, the Paleoenvironmental Arctic Sciences initiative, and the West Antarctic Ice Sheet Initiative, all sponsored by the US National Science Foundation. He was a senior editor of the journal Quaternary Research, and is currently director of the Quaternary Research Center. He has published more than 60 peer-reviewed articles in international journals.
