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...

What has become clear from the science is that we cannot burn all of the fossil fuels without creating a very different planet.
Because cap and trade is enforced through the selling and trading of permits, it actually perpetuates the pollution it is supposed to eliminate.
Well, you know what happens to crime when the heat goes up.
Our analysis shows that, for the extreme hot weather of the recent past, there is virtually no explanation other than climate change. The deadly European heat wave of 2003, the fiery Russian heat wave of 2010 and catastrophic droughts in Texas and Oklahoma last year [2011] can each be attributed to climate change. The odds that natural variability created these extremes are minuscule, vanishingly small. To count on those odds would be like quitting your job and playing the lottery every morning to pay the bills.
As a government employee, you can't testify against the government.
The carbon emissions from tar shale and tar sands would initiate a continual unfolding of climate disasters over the course of this century. We would be miserable stewards of creation. We would rob our own children and grandchildren.
The democratic process is supposed to be one person one vote, but it turns out that money is talking louder than the votes.
Adding CO2 to the air is like throwing another blanket on the bed.
Jail threats did not dissuade Martin Luther King - and intergenerational justice is a moral issue of comparable magnitude to civil rights.
Global warming isn't a prediction. It is happening.
There is still time to act and avoid a worsening climate, but we are wasting precious time,
It has become very difficult for anyone to argue that observed global warming is natural variability. We have good reason for being able to say that the world will be warmer by about a quarter of a degree in the next decade. It's the same reason we had 10 years ago when we said that the 1990s would be warmer than the 1980s: The planet is out of equilibrium.
As species are exterminated by shifting climate zones, ecosystems can collapse, destroying more species.
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.
