I think we have a very brief window of opportunity to deal with climate change. No longer than a decade at most.

More quotes by James Hansen
In view of the immense power of natural weather and climate fluctuations and the great buffering capacity of the Earth, especially the ocean, it is easy to be skeptical about whether small anthropogenic changes of atmospheric composition can have important practical impacts.
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 warmest years over the last century occurred in the last eight years.
James Hansen
Adding CO2 to the air is like throwing another blanket on the bed.
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
As a government employee, you can't testify against the government.
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
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
The five-year mean global temperature has been flat for the last decade
James Hansen
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.
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
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.
James Hansen
The 5-year mean global temperature has been flat for the last decade, which we interpret as a combination of natural variability and a slow down in the growth rate of net climate forcing.
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 trains carrying coal to power plants are death trains. Coal-fired power plants are factories of death.
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
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
I tend to be naive and gullible, I guess, but I try to believe that governments believe what they say.
James Hansen
The evidence for human-made climate change is overwhelming.
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.
