RAYMOND S. BRADLEY is a University Distinguished Professor of Geosciences and director of the
Climate Systems Research Center at the University of Massachusetts. Dr. Bradley's research interests are
in climatology and paleoclimatology, with a particular focus on the postglacial period (the past 12,000
years). Dr. Bradley has written or edited 12 topics on these subjects, including Paleoclimatology:
Reconstructing Climates of the Quaternary and Climate Change and Society (with N.E. Law). He has
been an advisor to various government and international agencies, including those in the United States,
Switzerland, Sweden, and the United Kingdom, and in particular for NSF, NOAA, IPCC, and the U.S.-
Russia Working Group on Environmental Protection, and the International Geosphere-Biosphere
Program, Stockholm, Sweden. He is a fellow of the AGU, the Arctic Institute of North America, and the
AAAS. He received an honorary doctorate from Lancaster University, England, for his contributions to
paleoclimatology. He was also awarded the Oeschger Medal of the European Geosciences Union. Dr.
Bradley earned his Ph.D. at the University of Colorado, Boulder. He served previously on the NRC's
Panel on Climate Variability on Decade-to-Century Time Scales, the Grasslands Study Panel, and the
Committee on Monitoring and Trend Assessment in Acid Deposition.

JOANNA D. HAIGH is professor and head of the Department of Atmospheric Physics at Imperial
College, London. Prior to joining Imperial College as a lecturer, she was a research associate at Oxford
University. Dr. Haigh's research interests are in the area of radiative transfer in the atmosphere, climate
modeling, radiative forcing of climate change, and the influence of solar irradiance variability on climate.
She has been vice president of the Royal Meteorological Society, editor of Quarterly Journal of the Royal
Meteorological Society , and a lead author of the IPCC Third Assessment, and she has acted on many U.K.
and international panels. Currently she is the U.K. representative to the International Association of
Meteorology and Atmospheric Sciences, editor of the Journal of the Atmospheric Sciences , and a member
of the Royal Society's Climate Change Advisory Group. She is a fellow of the Institute of Physics and of
the Royal Meteorological Society, and she has received the 2004 Charles Chree Medal of the Institute of
Physics and the 2010 Adrian Gill Prize of the Royal Meteorological Society for her work on solar
influences on climate. She earned her D.Phil. from the University of Oxford.
