Margaret S. Torn is the lead of Biosphere-Atmosphere Interactions Program Domain, and Senior Advisor in the Climate and Ecosystem Sciences Division. She is also the Program Lead for Atmospheric Systems Research and Terrestrial Ecosystems Science. In the former Earth Sciences Division Dr. Torn was the co-lead for the former Climate and Carbon Sciences Program Area. At U.C. Berkeley, she is an Adjunct Associate Professor in Energy and Resources Department.
Dr. Torn is an ecologist and biogeochemist who studies the natural carbon cycle and anthropogenic influence on the carbon cycle through land use (including bio-energy crops and sequestration management) and climate change. This work uses field experiments, isotopic analysis (14C, 13C), laboratory analysis, and mathematical models. Dr. Torn studies climate change impacts on ecosystems and the services they provide to society. She also studies the influence of the land surface on climate, including the potential for ecosystem-climate feedbacks to contribute to abrupt climate change. She has published work on climate change impacts on wildfire, on biodiversity, and on ecosystem sources and sinks of greenhouse gases. At Berkeley, Torn teaches a class on climate change impacts, adaptation, and vulnerability, and a seminar on food systems.
