James Hansen

James Edward Hansen (born 29 March 1941) is an American adjunct professor in the Department of Earth and Environmental Sciences at Columbia University. He is best known for his research in climatology, his 1988 Congressional testimony on climate change that helped raise broad awareness of global warming, and his advocacy of action to avoid dangerous climate change. In recent years he has become a climate activist to mitigate the effects of climate change, on a few occasions leading to his arrest.

In 2000 Hansen advanced an alternative view of global warming, arguing that the 0.74±0.18°C rise in average global temperatures over the previous 100 years had been driven mainly by greenhouse gases other than carbon dioxide, such as methane. However, even then he supported limiting CO2 emissions "because the future balance of forcings is likely to shift toward dominance of CO2 over aerosols" -- as it has.

Early life and education

Hansen was born in Denison, Iowa to James Ivan Hansen and Gladys Ray Hansen. He was trained in physics and astronomy in the space science program of James Van Allen at the University of Iowa. He obtained a B.A. in Physics and Mathematics with highest distinction in 1963, an M.S. in Astronomy in 1965 and a Ph.D. in Physics, in 1967, all three degrees from the University of Iowa. He participated in the NASA graduate traineeship from 1962 to 1966 and, at the same time, between 1965 and 1966, he was a visiting student at the Institute of Astrophysics at the University of Kyoto and in the Department of Astronomy at the University of Tokyo. Hansen then began work at the Goddard Institute for Space Studies in 1967.

    Famous quotes by James Hansen:

    "an old, hardheaded, Western redneck."
    "I can see this train coming down the track,"
    "If there's one place that I could put my finger on and say what's the No. 1 place that if a rogue aircraft came in and you had trouble it would really have a huge amount of trouble, it would have to be Houston, Texas. Boy, that could just bring America to its knees, almost."
    "I think you have a base that can be a credit to this area, more so. I guess I didn't understand the importance of this area to America."
    "I've never seen such great support as you see from the folks in Texas. They really put their money where their mouth is."
    "I really think the Navy is wrong on this one."
    "I'm probably the hardest head of the bunch (of nine commissioners),"
    "I put a little more emphasis (than the other commissioners did) on the lack of savings when it seemed obvious that we had way too much infrastructure,"
    "What really won that (decision in favor of Groton) was Rob Simmons, ... He did a phenomenal job."
    "I made the vote predicated on what I thought was right."
