Gavin Schmidt is a climate modeller at the NASA Goddard Institute for Space Studies in New York and is interested in modeling past, present and future climate. He works on developing and improving coupled climate models and, in particular, is interested in how their results can be compared to paleoclimatic proxy data. He also works on assessing the climate response to multiple forcings, such as solar irradiance, atmospheric chemistry, aerosols, and greenhouse gases.

He received a BA (Hons) in Mathematics from Oxford University, a PhD in Applied Mathematics from University College London and was a NOAA Postdoctoral Fellow in Climate and Global Change Research. He serves on the CLIVAR/PAGES Intersection and the Earth System Modeling Framework Advisory Panels and is an Associate Editor for the Journal of Climate. He was cited by Scientific American as one of the 50 Research Leaders of 2004, and has worked on Education and Outreach with the American Museum of Natural History, the College de France and the New York Academy of Sciences. He has over 50 peer-reviewed publications.

Dr. Michael E. Mann is a member of the Penn State University faculty, holding joint positions in the Departments of Meteorology and Geosciences, and the Earth and Environmental Systems Institute (ESSI). He is also director of the Penn State Earth System Science Center (ESSC).

Dr. Mann received his undergraduate degrees in Physics and Applied Math from the University of California at Berkeley, an M.S. degree in Physics from Yale University, and a Ph.D. in Geology & Geophysics from Yale University. His research focuses on the application of statistical techniques to understanding climate variability and climate change from both empirical and climate model-based perspectives. Current areas of research include paleoclimate data synthesis and statistical climate reconstruction using climate "proxy" data networks, and model/data comparisons aimed at understanding the long-term behavior of the climate system and its relationship with possible external (including anthropogenic) "forcings" of climate. Other areas of active research include development of statistical methods for climate signal detection, and investigations of the response of geophysical and ecological systems to climate variability and climate change scenarios.

Dr. Mann was a Lead Author on the "Observed Climate Variability and Change" chapter of the Intergovernmental Panel on Climate Change (IPCC) Third Scientific Assessment Report. He has been organizing committee chair for the National Academy of Sciences 'Frontiers of Science' and has served as a committee member or advisor for other National Academy of Sciences panels. He served as editor for the 'Journal of Climate' and has been a member of numerous international and U.S. scientific advisory panels and steering groups. Dr. Mann has been the recipient of several fellowships and prizes, including selection as one of the 50 leading visionaries in Science and Technology by Scientific American, the outstanding scientific publication award of the National Oceanographic and Atmospheric Administration (NOAA), and recognition by the Institute for Scientific Information (ISI) for notable citation of his refereed scientific research. He is author of more than 100 peer-reviewed and edited publications.

I am a physicist by training and have affiliations with the Norwegian Meteorological Institute (met.no) and the Oslo Climate Group (OCG) [My views here are personal and may not necessarily represent those of RegClim, OCG, met.no, or the mentioned societies]. I have a D.Phil in physics from Atmospheric, Oceanic & Planetary Physics at Oxford University in the United Kingdom. Recent work involve a good deal of statistics (empirical-statistical downscaling, trend analysis, model validation, extremes and record values), but I have also had some experience with electronics, cloud micro-physics, ocean dynamics/air-sea processes and seasonal forecasting. In addition, I wrote the book 'Solar Activity and Earth's Climate' (2002), published by Praxis-Springer, and I was a member of the council of the European Meteorological Society for the period (2004-2006), representing the Nordic countries and the Norwegian Meteorology Society.

In my work, I often get questions from media and lay persons about climate change. I believe it is necessary to approach these questions with identifying what we really don't know and what we are more sure about. I believe that some of Karl Popper ideas about falsification can be useful.

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.

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. Dr. Archer has worked on the ongoing mystery of the low atmospheric CO₂ concentration during glacial time 20,000 years ago, and on the fate of fossil fuel CO₂ on geologic time scales in the future, and its impact on future ice age cycles, ocean methane hydrate decomposition, and coral reefs. Archer has written a textbook for non-science major undergraduates called "Global Warming: Understanding the Forecast" published by Blackwell. More information can be found here.
