We have known since the 1800s that carbon dioxide traps heat in the atmosphere. The right amount keeps the climate conducive to human life.

If we fail to act, we will end up with a different planet.
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
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
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
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.

As a government employee, you can't testify against the government.

Adding CO2 to the air is like throwing another blanket on the bed.

Rising carbon price is essential to 'decarbonize' the economy - to remove the nation towards the era beyond fossil fuels.

Some Democrats deserve to be criticized.

The trains carrying coal to power plants are death trains. Coal-fired power plants are factories of death.
James Hansen
Image
'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

...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.

I tend to be naive and gullible, I guess, but I try to believe that governments believe what they say.
James Hansen
Image
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
Image
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
Image
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 forcings that drive long-term climate change are not known with an accuracy sufficient to define future climate change.
James Hansen

It would be immoral to leave young people with a climate system spiraling out of control.
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.

The evidence for human-made climate change is overwhelming.
