Climate Change and Global Food Production


Abstract: Humans are changing the Earth's environment. By the middle of this century, increasing greenhouse gases due to burning of fossil fuel will cause the average temperature in the tropics and subtropics to exceed that experienced throughout human history. In this talk, I will summarize the knowable -- and perhaps inescapable -- consequences for global food production. The greatest losses in grain production will be in developing countries, where today one billion people are malnourished and depend greatly on agriculture for income and food security. Significant losses will also be experienced in some of the world's bread baskets -- the US, Europe, Russia and China.

About the speaker: David Battisti is The Tamaki Endowed Chair of Atmospheric Sciences at the University of Washington. His research is focused on understanding how the interactions between the ocean, atmosphere, land and sea ice lead to variability in climate on time scales from seasonal to decades. His previous research includes coastal oceanography, the physics of the El Nino/Southern Osciallation (ENSO) phenomenon, midlatitude atmosphere/ocean variability and variability in the coupled atmosphere/sea ice system in the Arctic. Battisti is presently working to improve the El Nino models and their forecast skill, to understand the mechanisms responsible for the drought cycles in the Sahel, and to better understand the monsoons. He is also working on the impacts of climate variability and climate change on food production in Mexico, Indonesia and China. Battisti has an adjunct position at the Geophysical Institute, UiB.
