The five-year mean global temperature has been flat for the last decade, which we interpret as a combination of natural variability and… — James Hansen Copy Share Image
The danger is that the compromises and special interests inherent in Kyoto-style targets and cap-and-trade will be accepted because of bureaucratic momentum. — James Hansen Copy Share Image
The last time the world was three degrees warmer than today-which is what we expect later this century-sea levels were 25m higher.… — James Hansen Copy Share Image
Climate change is analogous to Lincoln and slavery or Churchill and Nazism: it's not the kind of thing where you can compromise. — James Hansen Copy Share Image
We're handing them [young people & future generations] a climate system which is potentially out of their control. We're in an emergency:… — James Hansen Copy Share Image
The most difficult task, phase-out over the next 20-25 years of coal use that does not capture COâ‚‚, is Herculean, yet feasible… — James Hansen Copy Share Image
On a per capita basis, Britain is responsible for more of the carbon dioxide now in the atmosphere than any other nation… — James Hansen Copy Share Image
Scientists will say we can't blame global warming for any single event. In a sense that's right, but the fact that the… — James Hansen Copy Share Image
We have to, in the next ten years, begin to decrease the rate of carbon dioxide emissions and then flatten it out.… — James Hansen Copy Share Image
In view of the immense power of natural weather and climate fluctuations and the great buffering capacity of the Earth, especially the… — James Hansen Copy Share Image
Only in the last few years did the science crystallize, revealing the urgency - our planet really is in peril. If we… — James Hansen Copy Share Image
After spending three or four years interacting with the Bush administration, I realized they were not taking any actions to deal with… — James Hansen Copy Share Image
Goals and caps on carbon emissions are practically worthless, if coal emissions continue, because of the exceedingly long lifetime of carbon dioxide… — James Hansen Copy Share Image
We have known since the 1800s that carbon dioxide traps heat in the atmosphere. The right amount keeps the climate conducive to… — James Hansen Copy Share Image
As species are exterminated by shifting climate zones, ecosystems can collapse, destroying more species. — James Hansen Copy Share Image
...the global surface albedo [surface whiteness] and greenhouse gas changes account for practically the entire global climate change. — James Hansen Copy Share Image
Global warming has already triggered a sea level rise that could reach from 6 metres (19.69 ft) to 25 metres (27.34 yards). — James Hansen Copy Share Image
The climate system is being pushed hard enough that change will become obvious to the man in the street in the next… — James Hansen Copy Share Image
We have at most ten years—not ten years to decide upon action, but ten years to alter fundamentally the trajectory of global… — James Hansen Copy Share Image
The carbon emissions from tar shale and tar sands would initiate a continual unfolding of climate disasters over the course of this… — James Hansen Copy Share Image
...chief executives of large fossil fuel companies to [should] be put on trial for high crimes against humanity and nature; [Hansen] accusing… — James Hansen Copy Share Image
We have at most ten years - not ten years to decide upon action, but ten years to alter fundamentally the trajectory… — James Hansen Copy Share Image
What is frustrating people, me included, is that democratic action affects elections but what we get then from political leaders is greenwash. — James Hansen Copy Share
What makes tar sands particularly odious is that the energy you get out in the end, per unit carbon dioxide, is poor. It's equivalent… — James Hansen Copy Share
We are on the precipice of climate system tipping points beyond which there is no redemption. — James Hansen Copy Share
Jail threats did not dissuade Martin Luther King - and intergenerational justice is a moral issue of comparable magnitude to civil rights. — James Hansen Copy Share
The United States did not sign Kyoto, yet its emissions are not that different from the countries that did sign it. — James Hansen Copy Share
The five-year mean global temperature has been flat for the last decade, which we interpret as a combination of natural variability and a slow… — James Hansen Copy Share
Rising carbon price is essential to 'decarbonize' the economy - to remove the nation towards the era beyond fossil fuels. — James Hansen Copy Share
Policy decisions on climate change are being deliberated every day by those without full knowledge of the science, and often with intentional misinformation spawned… — James Hansen Copy Share
Imagine a giant asteroid on a direct collision course with Earth. That is the equivalent of what we face now [with climate change], yet… — James Hansen Copy Share
The most difficult task, phase-out over the next 20-25 years of coal use that does not capture COâ‚‚, is Herculean, yet feasible when compared… — James Hansen Copy Share
As species are exterminated by shifting climate zones, ecosystems can collapse, destroying more species. — James Hansen Copy Share
I think we have a very brief window of opportunity to deal with climate change... no longer than a decade, at the most. — James Hansen Copy Share
The climate system is being pushed hard enough that change will become obvious to the man in the street in the next decade. — James Hansen Copy Share
