PROVO — David Battisti of the University of Washington will speak tonight at Brigham Young University on "Greenhouse Warming: Science, Projections and Uncertainties" for the 2008 Quey Hebrew Memorial Lecture from 7:30 to 9 p.m. in B092 Joseph F. Smith Building.

Prior to Battisti's lecture, there will be a reception with the speaker at 7 p.m. The public is welcome to attend both events. The lecture is sponsored by the department of geological sciences.

Battisti will address the state of the science of global warming, what we know will happen to the climate locally and globally and why some uncertainties exist. He will also show his projections on future climate based on current research.

Battisti served for five years as co-chairman of the Science Steering Committee for the U.S. Program on Climate and on numerous international science panels on Committees of the National Research Council. He is co-author of several international science plans and has more than 70 publications in peer-review journals in atmospheric sciences and oceanography.
