Susan Solomon, an atmospheric chemist, Antarctic researcher and expert on climate change, will present the 2009 Thomas Condon Lecture at Oregon State University.

The free public lecture, titled "A Tale For Our Times: Something for Everyone About Climate Change and the Reasons for Climate Gridlock," is scheduled for 7:30 p.m. Wednesday in Austin Auditorium of the LaSells Stewart Center at OSU. The Condon Lecture, named after a pioneer of Oregon geology, is for general audiences and intended to interpret significant scientific research for non-scientists.

Solomon is a senior scientist at the Earth System Research Laboratory of the National Oceanic and Atmospheric Administration in Boulder, Colo. She has written or co-written 200 scientific articles, received prestigious awards for her research and co-chaired the 2007 Intergovernmental Panel on Climate Change that won the Nobel Prize. Among other accomplishments, she was one of the first scientists to propose that chlorofluorocarbons might be causing ozone depletion.

Solomon also will give a more technical presentation on that topic - "Ozone Depletion: The Story of a Successful Global Environmental Agreement, and its Relevance for Climate Change" - in the George Moore Lecture. That event is scheduled for 4 p.m. Thursday, Oct. 15, at 4 p.m. in Gilfillan Auditorium, sponsored by the OSU Department of Geosciences.
