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.
It has become very difficult for anyone to argue that observed global warming is natural variability. We have good reason for being able to say that the world will be warmer by about a quarter of a degree in the next decade. It's the same reason we had 10 years ago when we said that the 1990s would be warmer than the 1980s: The planet is out of equilibrium.
...99 percent confident that the world really was getting warmer and that there was a high degree of probability that it was due to human-made greenhouse gases.
We cannot afford to put off change any longer. We have to get on a new path within this new administration. We have only four years left for Obama to set an example to the rest of the world. America must take the lead.
Planet Earth, creation, the world in which civilization developed, the world with climate patterns that we know and stable shorelines, is in imminent peril.
To be playing in a threesome with Neil Armstrong and Clint Eastwood was pretty incredible, ... For Peggy and I to be part of that was pretty heady stuff.

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.
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.
We can't afford to wait another 10 years.
My final obligation is not to Neil... it's not to any of the historical actors, it's to posterity, ... It's to try to tell the story as genuinely and as profoundly as I can for the benefit of readers who don't know the history and for readers who are going to come across this book hundreds of years from now.
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.
