Dr. James Hansen

THE THREAT TO THE PLANET

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.

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,
