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...

The greatest danger hanging over our children and grandchildren is initiation of changes that will be irreversible on any time scale that humans can imagine.
...the global surface albedo [surface whiteness] and greenhouse gas changes account for practically the entire global climate change.
Global warming has already triggered a sea level rise that could reach from 6 metres (19.69 ft) to 25 metres (27.34 yards).
The trains carrying coal to power plants are death trains. Coal-fired power plants are factories of death.
If humanity wishes to preserve a planet similar to that on which civilisation developed and to which life on Earth is adapted, paleoclimate evidence and ongoing climate change suggest that CO₂ will need to be reduced from its current 385 ppm [parts per million] to at most 350 ppm... If the present overshoot of this target CO₂ is not brief, there is a possibility of seeding irreversible catastrophic effects.
I've never seen such great support as you see from the folks in Texas. They really put their money where their mouth is.
Earth is warmer in 1988 than at any time in the history of instrumental measurements, The warming of a few degrees is going to take us to a world that is perhaps as different from today as the last ice age is from today.
Consider the perverse effect cap and trade has on altruistic actions. Say you decide to buy a small, high-efficiency car. That reduces your emissions, but not your country's. Instead it allows somebody else to buy a bigger S.U.V. - because the total emissions are set by the cap.
There's no win for us in talking about this.
I was ready to do a biography, ... But obviously, I was challenged by the daunting prospect of getting him to do it. I had no real confidence. There was nothing about my approach that I thought would convince him.
I think I was just trying to find my father, ... I hadn't been able to ask him these questions.
I think this is a more optimistic assessment of the chances for keeping climate change moderate in the next 50 years, and the way to do that is to focus on stopping the growth of several gases, ... Global Warming in the 21st Century: An Alternative Scenario.
The area below the proposed plat has experienced numerous slides that have resulted in residential property damage.
We've driven them out of the range that has existed for the last 1 million years. And the climate has not fully responded to changes that have already occurred.
