Richard Alley

Host, "Earth: The Operators' Manual" on PBS

Dr. Richard Alley has ranged from Antarctica to Greenland to help learn the history of Earth's climate, and whether the great ice sheets will fall in the ocean and flood our coasts. With more than 200 scientific publications, he has been asked to provide advice to the highest levels of government, and been recognized with numerous awards including election to the US National Academy of Sciences. He also has been compared to a "cross between Woody Allen and Carl Sagan" for his enthusiastic efforts to communicate the excitement and importance of Earth science to everyone.
