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
We are on the precipice of climate system tipping points beyond which there is no redemption.
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
'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
It would be immoral to leave young people with a climate system spiraling out of control.
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
CEOs of fossil energy companies know what they are doing and are aware of long-term consequences of continued business as usual. In my opinion, these CEOs should be tried for high crimes against humanity and nature.
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 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
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 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
Some Democrats deserve to be criticized.
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
What we are doing to the future of our children, and the other species on the planet, is a clear moral issue.
James Hansen
I tend to be naive and gullible, I guess, but I try to believe that governments believe what they say.
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
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
The trains carrying coal to power plants are death trains. Coal-fired power plants are factories of death.
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
