More quotes by James Hansen
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
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
I tend to be naive and gullible, I guess, but I try to believe that governments believe what they say.
James Hansen
If we fail to act, we will end up with a different planet.
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
What we are doing to the future of our children, and the other species on the planet, is a clear moral issue.
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
'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
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 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
We are on the precipice of climate system tipping points beyond which there is no redemption.
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
Rising carbon price is essential to 'decarbonize' the economy - to remove the nation towards the era beyond fossil fuels.
James Hansen
The five warmest years over the last century occurred in the last eight years.
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
The trains carrying coal to power plants are death trains. Coal-fired power plants are factories of death.
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
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
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
Well, you know what happens to crime when the heat goes up.
James Hansen
