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
We have known since the 1800s that carbon dioxide traps heat in the atmosphere. The right amount keeps the climate conducive to human life.
James Hansen
If we fail to act, we will end up with a different planet.
James Hansen
Money has too big an influence on our politics in Washington and somehow we need to do something about that.
James Hansen
...chief executives of large fossil fuel companies to [should] be put on trial for high crimes against humanity and nature [Hansen] accusing them of actively spreading doubt about global warming in the same way that tobacco companies blurred the links between smoking and cancer.
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
If we drive our fellow species to extinction, we will leave a far more desolate planet for our descendants than the world we inherited from our elders.
James Hansen
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.
James Hansen
The five-year mean global temperature has been flat for the last decade
James Hansen
The trains carrying coal to power plants are death trains. Coal-fired power plants are factories of death.
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
We are on the precipice of climate system tipping points beyond which there is no redemption.
James Hansen
I was lucky to grow up at a time when it was not difficult for the child of a tenant farmer to make his way to the state university.
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
'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
I think we have a very brief window of opportunity to deal with climate change. No longer than a decade at most.
James Hansen
'Cap and trade' generates special interests, lobbyists, and trading schemes, yielding non-productive millionaires, all at public expense. The public is fed up with such business. Tax with 100% dividend, in contrast, would spur our economy, while aiding the disadvantaged, the climate, and our national security.
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
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
The fact is fossil fuel carbon will stay in the surface climate system for millennia.
James Hansen
I tend to be naive and gullible, I guess, but I try to believe that governments believe what they say.
