COS Earth Transformed logoBy the year 2050, the increase in global temperature is projected to cause a 20 percent reduction in the yield of all of the major grains (maize, wheat, rice and soybeans).

Increasing stresses on the major crops due to climate change, coupled with the increasing demand for food due to increasing population and development, present significant challenges to achieving global food security.

At 3:30 p.m. Thursday (March 24), David Battisti, an atmospheric scientist at the University of Washington, will explore the likely impact of climate change and volatility on food production and availability in the foreseeable future.

Battost’s pre-recorded lecture is the first of four presentations from this year’s UA College of Science series, “Earth Transformed,” originally given at the Fox Theater in downtown Tucson. The ASA’s annual encore series offers east side residents a chance to see and hear these thought-provoking lectures while avoiding a trip downtown.

This year’s series offers fresh scientific perspectives on climate change and its impacts. No longer merely abstract projections for the future, these impacts are on-going and growing challenges for both humans and many of the natural systems upon which we depend.

Battisti’s March 24 ASA presentation is entitled “Climate Change
and Global Food Security.” Battisti is the Tamaki Endowed Chair of Atmospheric Sciences at the University of Washington.

He is currently working on the impacts of climate variability and climate change on food production in Mexico, Indonesia and China.

The remaining College of Science lectures: March 31: “Ecosystem Resilience” lecture by Russell Keith Monson; April 6: “Climate Change and Human Health” lecture by Kacey Ernst; and April 14: “Carbon Sequestration: Can We Afford It?” lecture by Kimberly Ogden.
