Susan Solomon, research scientist at the National Oceanic and Atmospheric Administration (NOAA), will deliver the 2010 Ullyot Public Affairs Lecture, “A Tale for Our Times: Something For Everyone About Climate Change and The Reasons for Climate Gridlock.” A reception will follow immediately after the lecture. This event is free and open to the public. Registration required by November 11. The Ullyot Public Affairs Lecture emphasizes the positive role that chemistry and related sciences play in our lives. Solomon’s talk aims to explain the science of climate change and to illustrate why international agreement on climate-change policy has proven particularly difficult. Solomon is widely recognized as a leader in the field of atmospheric science. She pioneered the theory explaining why the ozone hole occurs in Antarctica and obtained some of the first chemical measurements that helped to establish chlorofluorocarbons as its cause. Don't miss this opportunity to hear a pioneering climate researcher describe her work.
