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
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
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
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
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
Some Democrats deserve to be criticized.
James Hansen
The five warmest years over the last century occurred in the last eight years.
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.
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 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
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 forcings that drive long-term climate change are not known with an accuracy sufficient to define future climate change.
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
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
Recent warming coincides with rapid growth of human-made greenhouse gases. The observed rapid warming gives urgency to discussions about how to slow greenhouse gas emissions.
James Hansen
Adding CO2 to the air is like throwing another blanket on the bed.
James Hansen
We are on the precipice of climate system tipping points beyond which there is no redemption.
James Hansen
Planet Earth, creation, the world in which civilization developed, the world with climate patterns that we know and stable shorelines, is in imminent peril.
James Hansen
The fact is fossil fuel carbon will stay in the surface climate system for millennia.
James Hansen
