Because cap and trade is enforced through the selling and trading of permits, it actually perpetuates the pollution it is supposed to eliminate.

We're running out of time.

Imagine a giant asteroid on a direct collision course with Earth. That is the equivalent of what we face now with climate change, yet we dither.

We are on the precipice of climate system tipping points beyond which there is no redemption.

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

Global warming has already triggered a sea level rise that could reach from 6 metres (19.69 ft) to 25 metres (27.34 yards).

What we are doing to the future of our children, and the other species on the planet, is a clear moral issue.

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.

What has become clear from the science is that we cannot burn all of the fossil fuels without creating a very different planet.

It's as certain that as long as fossil fuels are the cheapest energy, we will just keep burning them.

We have at most ten years—not ten years to decide upon action, but ten years to alter fundamentally the trajectory of global greenhouse emissions.

It all comes down to who is by your side and who is willing to stand up for love even when it seems impossible.

I think the easiest people to fool are ourselves. Fooling ourselves may even be a necessary precondition for fooling others.

Just my luck: My bloodthirsty killing machine was better with both kids and women than I was.

Some of my ancestors fought in the American Revolution. A few more wore red coats, a few wore blue coats, and the rest wore no coats at all. We never did figure out who won that war.

There is only one justification for having sinned, and that is to be glad of it.

I keep going over a sentence. I nag it, gnaw it, pat and flatter it.

Much shedding of blood, many great actions, and triumphs, toil and perseverance are the end of all things human.

I like to think that even with some of the more intense ones sometimes there is humour in there, you try to make a complete human being, whether the guy is good or bad.

No civilisation can claim to have a monopoly on universal values and no one can claim to be always faithful to his own values.

What with the reviews of critics, the sarcasms of one's friends, the reproaches of one's own taste, there's precious little peace after publishing a book.
