How long have we got? We have to stabilize emissions of carbon dioxide within a decade, or temperatures will warm by more than one degree... We don't have much time left.

More quotes by James Hansen
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.
James Hansen
Politicians think that if matters look difficult, compromise is a good approach. Unfortunately, nature and the laws of physics cannot compromise - they are what they are.
James Hansen
I tend to be naive and gullible, I guess, but I try to believe that governments believe what they say.
James Hansen
I think we have a very brief window of opportunity to deal with climate change. No longer than a decade at most.
James Hansen
The forcings that drive long-term climate change are not known with an accuracy sufficient to define future climate change.
James Hansen
Only in the last few years did the science crystallize, revealing the urgency - our planet really is in peril. If we do not change course soon, we will hand our children a situation that is out of their control.
James Hansen
Because cap and trade is enforced through the selling and trading of permits, it actually perpetuates the pollution it is supposed to eliminate.
James Hansen
A level of no more than 350 ppm is still feasible, with the help of reforestation and improved agricultural practices, but just barely - time is running out.
James Hansen
The five-year mean global temperature has been flat for the last decade
James Hansen
What we are doing to the future of our children, and the other species on the planet, is a clear moral issue.
James Hansen
Adding CO2 to the air is like throwing another blanket on the bed.
James Hansen
We have to, in the next ten years, begin to decrease the rate of carbon dioxide emissions and then flatten it out. If that doesn't happen in ten years, we're going to be passing certain tipping points. If the ice sheets begin to disintegrate, what can you do about it? You can't tie a rope around an ice sheet.
James Hansen
The five warmest years over the last century occurred in the last eight years.
James Hansen
'Goals' and 'caps' on carbon emissions are practically worthless, if coal emissions continue, because of the exceedingly long lifetime of carbon dioxide in the air.
James Hansen
We are on the precipice of climate system tipping points beyond which there is no redemption.
James Hansen
If we fail to act, we will end up with a different planet.
James Hansen
It would be immoral to leave young people with a climate system spiraling out of control.
James Hansen
Rising carbon price is essential to 'decarbonize' the economy - to remove the nation towards the era beyond fossil fuels.
James Hansen
The last time the world was three degrees warmer than today-which is what we expect later this century-sea levels were 25m higher. So that is what we can look forward to if we don't act soon.
James Hansen
Well, you know what happens to crime when the heat goes up.
