A contributor and lead author to several reports of the U.N. International Panel on Global Climate Change will speak June 5 at a luncheon sponsored by the Center for the American Experiment. The presentation is entittled "Searching For Climate Change: A More Temperate Take on Global Warming."

Prof. John R. Christy -- one of a handful of scientists to actually build "data sets of climate variation and change from scratch" -- will talk about how finding "dramatic changes in climate systems" is really quite difficult.

Dr. Christy is professor of Atmospheric Science and Director of the Earth System Science Center at the University of Alabama in Huntsville, where he and a colleague have collected and analyzed global temperature information from satellite-observed microwave data going back to 1979. For this breakthrough, he was awarded NASA's Medal for Exceptional Scientific Achievement. He likewise has been honored by the American Meteorological Society, which later named him a Fellow -- and since 2000, he's also been known as "Alabama State Climatologist."

The forum will be held from noon to 1:30 p.m. June 5 at the DoubleTree Park Place Hotel, 1500 Park Place Blvd., in St. Louis Park. The cost for non-American Experiment members is $30. Register online or contact Peter Zeller at Peter.Zeller@AmericanExperiment.org, (612) 338-3605 or fax to (612) 338-3621.
