"Climate Change and Los Angeles: A Close-up View of the Future"

Alex Hall, Ph.D., Professor, University of California, Los Angeles

October 23, 2013

• Presentation
• Interview

Dr. Hall will present results from The Climate Change in the Los Angeles Region Project, an ongoing series of studies to predict regional climate at the middle and end of the 21st century under "mitigation" and "business-as-usual" greenhouse gas emissions scenarios. Using a combination of dynamical and statistical techniques, Dr. Hall and his team developed very high resolution regional models that "downscale" more than 30 global models. This allowed the team to zoom in on the LA region, producing climate change projections at a 2-kilometer (1.2 mile) resolution. In this presentation, Dr. Hall will discuss his downscaling methods, summarize what his team discovered about temperature, snowfall, and other aspects of climate in the LA region, and explore the implications of his work for policymakers and the public.
