Chair's Lecture with Alex Hall
"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
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.
Dr. Hall is a professor in UCLA’s Department of Atmospheric and Oceanic Sciences and a member of UCLA’s Institute of the Environment and Sustainability, where he is the faculty director of the UCLA Center for Climate Change Solutions. Dr. Hall is an internationally recognized climate scientist and a lead author of the Intergovernmental Panel on Climate Change (IPCC) 5th Assessment Report chapter on Climate Phenomena and their Relevance for Future Regional Climate Change. His previous work on the 2007 IPCC report includes helping to develop the global climate models used by the IPCC. Professor Hall is a recipient of the NSF Graduate Fellowship (1993-1996), the NASA Earth System Science Fellowship (1996-1998), the Lamont Fellowship (1999-2001), and the National Science Foundation Career Award (2002-2007).
The Chair of the California Air Resources Board invites guests to speak on environmental subjects involving air pollution and global warming. Find additional lectures on the Chair's Lecture Series webpage.
