Will the ongoing CO2 buildup cause a severe drying of the western U.S.?
Tuesday February 2nd
Room 417 Schermerhorn Hall
Summary: Based on the record for the last 25 K yrs kept in closed basin lakes, stalagmites and polar ice, the earth's hydrologic cycle shifts in union as the earth's temperature and the interhemispheric temperature difference changes. Based on this evidence, the American west will experience a severe drying as CO2 builds up in our atmosphere.
Newberry Professor Wally Broecker's research focusses on the role the oceans play climate change. He places strong emphasis on using isotopes as a means to understand physical mixing and chemical cycling in the ocean in order to uncover what it takes to trigger switches in the climate system's mode of operation. Understanding the mechanism behind abrupt switches in the climate system's mode of operation is the first step to making good predictions about future climate change.
Wally completed both his undergraduate and graduate degrees at Columbia University and has spent his entire career as a geochemist at Columbia's Lamont-Doherty Earth Observatory. Wally has won nearly every top honor in his field, including the 1996 National Medal of Science and, more recently, the $885,000 Balzan Prize, given for science in the service of humanity, and the newly founded Frontiers of Knowledge Award in Climate Change Research, one of the world’s largest science prizes. He continues to teach, write, do research and advocate for ways to address human-induced global climate change.
Future talks are scheduled for Tuesdays from 12:15-1:00pm in Room 417 Schermerhorn Hall. Attendees are welcome to bring their lunch.
All are welcome to attend!
