More quotes by 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.
James Hansen
Image
I tend to be naive and gullible, I guess, but I try to believe that governments believe what they say.
James Hansen
Image
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
Image
I think we have a very brief window of opportunity to deal with climate change. No longer than a decade at most.
James Hansen
Image
Adding CO2 to the air is like throwing another blanket on the bed.
James Hansen
Image
The forcings that drive long-term climate change are not known with an accuracy sufficient to define future climate change.
James Hansen
Image
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

Well, you know what happens to crime when the heat goes up.
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
Image
Rising carbon price is essential to 'decarbonize' the economy - to remove the nation towards the era beyond fossil fuels.
James Hansen
Image
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
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
Image
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
Image
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
Image
The evidence for human-made climate change is overwhelming.

The urgency derives from the nearness of climate tipping points.
James Hansen
Image
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
Image
Money has too big an influence on our politics in Washington and somehow we need to do something about that.
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.
