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. 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.

William M. Connolley is a climate modeller with the British Antarctic Survey.

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.

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.

Dr. Thibault de Garidel-Thoron is currently a post-doctoral associate at the Institute of Marine and Coastal Sciences at Rutgers University. His main scientific interest is to reconstruct past tropical climate changes using micropaleontological and geochemical proxies from oceanic sediment records.
Dr. de Garidel received his Bachelor’s degree in Earth Sciences from the Université Lyon I, France, completed a Master in the Université Bordeaux I, France and a Ph.D. in Geosciences at CEREGE, Université Paul Cézanne (a.k.a. Aix-Marseille III).

David Archer is a computational ocean chemist at the University of Chicago. He has published research on the carbon cycle of the ocean and the sea floor, at present, in the past, and in the future. The ocean contains fifty times more carbon than does the atmosphere, and the ocean controls the CO2 concentration of the atmosphere on time scales of thousands to hundreds of thousands of years.

Raymond Pierrehumbert is the Louis Block Professor in Geophysical Sciences at the University of Chicago, having earlier served on the atmospheric science faculties of MIT and Princeton.
He received an A.B. degree in Physics from Harvard, was then a Knox Fellow in the Department of Applied Mathematics and Theoretical Physics at Cambridge University, and completed his PhD on hydrodynamic stability theory at MIT, in the Department of Aeronautics and Astronautics. He was a lead author of the IPCC Third Assessment Report, and a co-author of the National Research Council study on abrupt climate change. He is a Fellow of the American Geophysical Union.
