James Hansen
James Edward Hansen 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." |

Iconic Climatologist James Hansen appeared at a COP21 press conference, where he strongly critiqued the anticipated Paris agreement as ‘half-assed’ and ‘half baked’ for once again relying upon voluntary emission reductions. Hansen argued instead for a cap and dividend approach to controlling carbon emissions.

We made a video discussing some of the main points in our “Ice Melt” paper[1], which is about to be published in Atmos. Phys. Chem.
The main point that I want to make concerns the threat of irreparable harm, which I feel we have not communicated well enough to people who most need to know, the public and policymakers. I’m not sure how we can do that better, but I comment on it at the end of this transcript. |
