A cosmic twin study

Astrobiologist David Grinspoon takes the anthropocene off-planet to our nearest cosmic neighbor Venus and discusses what we learn about climate change here on Earth from Venus’ catastrophic green-house effect.  He also takes some time to address George Carlin’s environmental philosophy and talk about his childhood friend and mentor, Carl Sagan.

David Grinspoon
Dr. David Grinspoon is interested in the cosmic context for life, so he studies the climate history of planets and the factors that influence the origin and evolution of life on Earth and elsewhere.  He pursues these interests by participating on spacecraft teams at NASA and the European Space Agency, and through constructing computer models of planetary climate evolution.  David Grinspoon is the curator of astrobiology in the Department of Space Sciences at the Denver Museum of Nature & Science.  In 2012, he was named the first Baruch S. Blumberg NASA/Library of Congress Chair in Astrobiology in the John W. Kluge Center at the Library of Congress. The chair is a joint project between the NASA Astrobiology Institute and the Kluge Center.  He is a well-known researcher in planetary science and the author of “Lonely Planets: The Natural Philosophy of Alien Life.”
