Understanding the local impacts of global climate change is crucial, especially in places like Aspen where warming poses a threat to the ski industry, the economic life-blood of the town. However, such regional-scale assessments are difficult to accomplish with a satisfactory degree of certainty. In this lecture, Gerald Meehl, senior climate scientist at the National Center for Atmospheric Research, offers the best-available scientific predictions for Aspen's future climate and discusses the implications these findings have for Aspens environment, economy, and society.
