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 120 peer-reviewed and edited publications, and recently co-authored with colleague Lee Kump the book Dire Predictions: Understanding Global Warming.

Caspar Ammann is a climate scientist working at the National Center for Atmospheric Research (NCAR). Dr. Ammann is interested in the reconstruction of natural climate forcings, natural climate variability, coupled modeling of natural and anthropogenic climate change, and data/model intercomparison. Dr. Ammann got his B.S. from Gymnasium Koeniz (Switzerland), his M.S. from the University of Bern (Switzerland), and a Ph.D. from the Department of Geosciences at the University of Massachusetts.

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.

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 has worked on assessing the climate response to multiple forcings, including solar irradiance, atmospheric chemistry, aerosols, and greenhouse gases.
