More quotes by James Hansen
...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.
James Hansen
'Goals' and 'caps' on carbon emissions are practically worthless, if coal emissions continue, because of the exceedingly long lifetime of carbon dioxide in the air.
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 fact is fossil fuel carbon will stay in the surface climate system for millennia.
James Hansen
Rising carbon price is essential to 'decarbonize' the economy - to remove the nation towards the era beyond fossil fuels.
James Hansen
Some Democrats deserve to be criticized.
James Hansen
The urgency derives from the nearness of climate tipping points.
James Hansen
We are on the precipice of climate system tipping points beyond which there is no redemption.
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
I think we have a very brief window of opportunity to deal with climate change. No longer than a decade at most.
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
'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
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
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
The trains carrying coal to power plants are death trains. Coal-fired power plants are factories of death.
James Hansen
If we fail to act, we will end up with a different planet.
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
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.
