Zitat des Tages von James Hansen:
I've tried to be a straight scientist doing the science and reporting it as best I can.
Global warming isn't a prediction. It is happening.
Scientists will say we can't blame global warming for any single event. In a sense that's right, but the fact that the frequency and intensity of these events is increasing you can blame on global warming.
Jail threats did not dissuade Martin Luther King - and intergenerational justice is a moral issue of comparable magnitude to civil rights.
I tend to be naive and gullible, I guess, but I try to believe that governments believe what they say.
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.
The five warmest years over the last century occurred in the last eight years.
After spending three or four years interacting with the Bush administration, I realized they were not taking any actions to deal with climate change. So, I decided to give one talk, and then it snowballed into another talk and eventually to even protesting and getting arrested.
Until the public demands otherwise, the policy makers will continue to serve their financiers.
Climate change is analogous to Lincoln and slavery or Churchill and Nazism: it's not the kind of thing where you can compromise.
With a fourth generation of nuclear power, you can have a technology that will burn more than 99 percent of the energy in the fuel. It would mean that you don't need to mine uranium for the next thousand years.
On a per capita basis, Britain is responsible for more of the carbon dioxide now in the atmosphere than any other nation on Earth because it has been burning it from the dawn of the Industrial Revolution.
You can't turn on your television without seeing these advertisements about clean coal, clean tar sands and the claim that there's more jobs associated with fossil fuels than other industries. That's of course not true. But they're hammering that into the voters' heads.
The United States did not sign Kyoto, yet its emissions are not that different from the countries that did sign it.
We need to send a message to Congress and the president that we want them to take the actions that are needed to preserve climate for young people and future generations and all life on the planet.
It's as certain that as long as fossil fuels are the cheapest energy, we will just keep burning them.
Some Democrats deserve to be criticized.
Money has too big an influence on our politics in Washington and somehow we need to do something about that.
You have no time to do the science if you're talking to the media.
The evidence for human-made climate change is overwhelming.
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 to burning coal in your automobile.
We have known since the 1800s that carbon dioxide traps heat in the atmosphere. The right amount keeps the climate conducive to human life.
Adding CO2 to the air is like throwing another blanket on the bed.
