Sierra Nevada

Climate Change in the Sierra Nevada

Using an innovative technique to produce high-resolution future climate projections, our team is answering key questions about the fate of the Sierra Nevada snowpack, a critical natural resource that not only supports an iconic ecosystem but also provides freshwater to millions of Californians.

Developing Metrics to Evaluate the Skill and Credibility of Downscaling

Within the climate science community, a variety of techniques are used to "downscale" information from global climate models and produce fine-scale projections of future climate, but the relative strengths and weaknesses of these techniques are not well-understood. In this project, we are comparing downscaling techniques and establishing best practices.

The Future of Extreme Precipitation in California

Our researchers are investigating the effects of climate change on heavy precipitation events in the state. Specifically, we're focusing on atmospheric rivers, moisture-laden filaments of air that move across oceans and produce heavy precipitation when they make landfall. Understanding how atmospheric rivers are affected in a changing climate is key to smart water planning in the future.

Los Angeles Skyline

Climate Change in the Los Angeles Region

The most comprehensive study of climate change in LA to date, the Climate Change in the Los Angeles Region Project was conducted by Center for Climate Science Faculty Director Alex Hall and his research group between 2010 and 2015. Dr. Hall and his team developed a novel method for bringing global climate model projections to high spatial resolution, creating neighborhood-by-neighborhood projections of future climate over the greater Los Angeles region under different scenarios of greenhouse gas emissions.
