THE THREAT TO THE PLANET

Dr. James Hansen


How can we avoid dangerous human-made climate change
Dr. James Hansen is one of the few scientists who have consistently warned that the impact that humans have on the climate is bringing about changes that are faster than we ever believed and may be irreversible if action is not taken now. Hansen is Director of the NASA Institute for Space Studies in New York City, and he teaches at Columbia. Since the late 1970s, he has worked on studies of the Earth's climate. He has run afoul of government censors since the 1980s. Repeatedly his testimony before Congress was suppressed or re-written.

Hansen says that the unprecedented and rising amounts of greenhouse gases added each year AND the speed at which we are altering the energy balance of the earth are completely out of the range of proven earth history of hundreds of thousands of years. Hansen fears that we may soon be reaching feedback mechanism or tipping points such as the melting of the ice sheets that has already begun on Greenland and West Antarctica.
In part one of this program Hansen gives a fascinating account of the earth's climate history, in part two he talks about solutions. Dr. Hansen's work - including the slide projections for this talk, can be found at < http://www.columbia.edu/~jeh1>

I added a third program, a collection of the most intriguing questions from the audience and answers, by Hansen, on issues such as sea level rise, hurricanes, interglacials, and the ongoing censorship of climate scientists by the Bush administration.
