James Hansen
James Edward Hansenis 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...

There is still time to act and avoid a worsening climate, but we are wasting precious time,
Imagine a giant asteroid on a direct collision course with Earth. That is the equivalent of what we face now [with climate change], yet we dither.
The climate dice are now loaded. Some seasons still will be cooler than the long-term average, but the perceptive person should notice that the frequency of unusually warm extremes is increasing. It is the extremes that have the most impact on people and other life on the planet.
You can't turn on your television without seeing these advertisements about clean coal, clean tar sands and the claim that there's more jobs associated with fossil fuels than other industries. That's of course not true. But they're hammering that into the voters' heads.
You can't tie a rope around the ice sheet. You can't build a wall around the ice sheets.
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.
If your child gets asthma, the fossil fuel industry doesn't pay. Or if there's a natural disaster, the bill is paid by the taxpayer, not the fossil fuel company.
For instance, they're using the economy as the reason not to consider taking action. I've been chastised for being a scientist saying we are damaging the economy in the long run. But you need to look at the broad problem. I think I'm free to do so and free to have my opinion.
After spending three or four years interacting with the Bush administration, I realized they were not taking any actions to deal with climate change. So, I decided to give one talk, and then it snowballed into another talk and eventually to even protesting and getting arrested.
I think I was just trying to find my father, ... I hadn't been able to ask him these questions.
I tend to be naive and gullible, I guess, but I try to believe that governments believe what they say.
Several times in Earth's history, rapid global warming occurred, apparently spurred by amplifying feedbacks. In each case, more than half of plant and animal species became extinct. New species came into being over tens and hundreds of thousands of years. But these are time scales and generations that we cannot imagine.
Injection of environmental and political perspectives in midstream of the science discussion cannot help the process of inquiry. I believe that persons with relevant scientific expertise should concentrate, with pride, on cool objective analysis, providing information to the public and decision-makers when it is found, but leaving the moral implications for later common consideration, or at most for summary inferential discussion.
