University of Chicago scientists available to comment on fourth report of Intergovernmental Panel on Climate Change

Feb. 1, 2007

The Intergovernmental Panel on Climate Change on Friday, Feb. 2, will release in Paris a summary of its Fourth Assessment Report (the full text of the report will follow later in the year). The following University of Chicago climatologists are available to journalists to comment on the report:

Ray Pierrehumbert, the Louis Block Professor in Geophysical Sciences. Pierrehumbert was a lead author of the IPCC’s Third Assessment Report, released in 2001. He studies the physics of climate, especially regarding the long-term evolution of the climates of Earth and Mars. He directs the Climate Systems Center, which develops software for rapidly conducting advanced climate simulations. Last December, he was co-author of an article describing how methane clouds affect atmospheric circulation on Titan, a moon of Saturn.

Pierrehumbert was a member of the National Research Council’s Panel on Abrupt Climate Change and its Societal Impacts (2000-2001). He currently serves on Chicago Mayor Daley’s Task Force on Climate Change, and on the National Oceanic and Atmospheric Administration’s Panel on Abrupt Change. He was a Guggenheim Fellow in 1996-97.

David Archer, Professor in Geophysical Sciences. Archer uses computer simulations to understand the balance between carbon dioxide levels in the oceans and in the atmosphere in the past to better predict the impact that changing levels will have on future climate. He contributes to Realclimate.org, where commentary written by working climate scientists can be accessed by journalists and the public.

Archer is working on a book with Stefan Rahmstorf of Potsdam University in Germany, called the Unofficial Guide to the Fourth Scientific Assessment. He also is the author of an undergraduate textbook for non-science majors, titled Global Warming: Understanding the Forecast. The book assesses both the natural and technological contributions to long-lived carbon dioxide in the atmosphere. Archer has another book in progress for a lay audience, titled From Here to Eternity: Global Warming in Geologic Time.

Journalists can arrange an interview with Pierrehumbert or Archer by calling Steve Koppes at (773) 702-8366.
