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.

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.

...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.

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
Image
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.

What we are doing to the future of our children, and the other species on the planet, is a clear moral issue.
James Hansen
Image
The fact is fossil fuel carbon will stay in the surface climate system for millennia.
James Hansen

If we fail to act, we will end up with a different planet.
James Hansen

As you get more global warming, you should see an increase in the extremes of the hydrological cycle - droughts and floods and heavy precipitation.

I tend to be naive and gullible, I guess, but I try to believe that governments believe what they say.

Money has too big an influence on our politics in Washington and somehow we need to do something about that.
