Listen to a Scientist
Below we present videos of a leading scientist talking about the causes and effects of climate change.
These videos are excerpts of a lecture by Richard Alley, Ph.D., at the Philadelphia Bar Association on November 6, 2014.
Dr. Richard Alley is a Penn State professor, environmental scientist, PBS host, book author, polar ice expert, bicycle enthusiast, geologist, Nobel Prize winner, Johnny Cash impersonator, former oil company employee, and—according to The New York Times’ Andy Revkin—a “cross between [acclaimed Hollywood director] Woody Allen and [late American astronomer] Carl Sagan.”
Richard is an Evan Pugh Professor of Geosciences in Penn State’s College of Earth and Mineral Sciences. His research interests focus on glaciology, sea level change and abrupt climate change, and he frequently discusses earth sciences on major media outlets, including NPR, BBC and PBS. He is widely credited with showing that the earth has experienced abrupt climate change in the past—and likely will again, based on his meticulous study of ice cores from Greenland and West Antarctica.
