Alex Hall is Professor in the Department of Atmospheric and Oceanic Sciences and Institute of the Environment and Sustainability and Director of the Center for Climate Science at UCLA. His research is focused on reducing climate change uncertainty at both regional and global scales.

At the global scale, he has pioneered the use of emergent constraints to evaluate global climate models and narrow the range of answers they give about future climate.

At the regional scale, he has been active in the development of downscaling techniques to understand climate change at the scales most relevant to people and ecosystems. Alex and his team at the Center for Climate Science use these techniques to create neighborhood-scale projections of future climate. They have recently completed downscaling studies over the Los Angeles region and the Sierra Nevada, and projects are currently under way to investigate the future of extreme precipitation and fire in California.

Alex was a Lead Author of the Intergovernmental Panel on Climate Change 5th Assessment Report’s chapter on regional climate change and a Contributing Author to its chapter on climate model evaluation. He was also Coordinating Lead Author of the Los Angeles Region Report, part of California’s Fourth Climate Change Assessment. In 2016, he received the American Geophysical Union’s Atmospheric Sciences Ascent Award.
