ANN ARBOR—The University of Michigan has several experts available to comment on climate change and global warming.

A new report from Great Britain says global climate change will devastate the world’s economy. Author Nicholas Stern is the former World Bank chief economist, and the 576-page Stern Review Report on the Economics of Climate Change is considered the most thorough projection of the economic impact or global warming to date.

U-M experts include:

• Joyce Penner, the Aksel Wiin-Nielsen Professor of Atmospheric Sciences, has conducted extensive research into climate and climate change; urban, regional and global tropospheric chemistry and budgets; cloud and aerosol interactions and cloud microphysics; and model development and interpretation. Penner has won the prestigious World Meteorological Organization’s Norbert Gerbier-Mumm International Award.

She’s a member of the International Commission on Atmospheric Chemistry and Global Pollution, and associate editor of the Journal of Climate. She’s a coordinating lead author on the chapter of the pending ” Intergovernmental Panel on Climate Change Third Assessment Report,” and has provided scientific briefings to Senate staff and the Subsidiary Body on Sustainable Technology, United Nations.

She can be reached at (734) 936-0519, or penner@umich.edu. For more on Penner, visit, http://data.engin.umich.edu/Penner/.

• Richard Rood, professor in the Department of Atmospheric, Oceanic and Space Sciences, is widely regarded as an expert in climate modeling, stratospheric and tropospheric chemistry modeling and data assimilation. One of his courses includes ” Climate Change: The Intersection of Science, Policy and Economics,” and he has received many awards for his research into climate change.

Among these are: Norbert Gerbier-Mumm International Award, by the World Meteorological Organization; NASA Group Achievement Awards; NASA Outstanding Leadership Medal; and NASA Exceptional Achievement Medal. He can be reached at (734) 647-3530, or rbrood@umich.edu. For more information, visit:

• Perry Samson, associate chair of the Department of Atmospheric, Oceanic and Space Sciences, and Arthur F. Thurnau Prof. of Atmospheric Science, is an expert in meteorology and science education.

He is widely known for research in meteorological analysis and interpretation of atmospheric trace constituents, regional transport and deposition of air pollutants, and development of internet-enabled learning objects. He can be reached at (734) 763-4217 or samson@umich.edu. For more on Samson, visit:
