Astronomy lectures and climate change

From the Silicon Valley Astronomy Lectures...a very interesting talk:
Take an entertaining and enlighting journey with astronomer and popular author Dr. David Grinspoon through the history of our solar system, discovering run away greenhouses and snowball planets. Compare the evolution of Venus, Earth, and Mars over the years and learn how studying the evolution of other planets can help us understand and predict climate change on Earth.
