A Sydney Ideas lecture by James E Hansen, director of the NASA Goddard Institute for Space Studies, New York and Adjunct Professor at Columbia University’s Earth Institute.
Trained in physics and astronomy, Hansen is best known for his Congressional testimony on climate change in the 1980s that helped raise broad awareness of global warming. He has been an active researcher in planetary atmospheres and climate science for nearly 40 years, with the last 30 years focused on climate research, publishing more than 100 scholarly articles on the latter topic.
Time Magazine designated Dr. Hansen as one of the world’s 100 most influential people in 2006, a tribute to his continuing efforts to serve the public through his scientific work.
