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.

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.

Writing is a combination of intangible creative fantasy and appallingly hard work.

I’ll make a beautiful corpse.

Behind every cloud is another cloud.

What I do isn't radical. It's just distinct in small ways.

Time passes. That's the rule. No matter what happens, no matter how much it might feel like everything in your life has been frozen around one particular moment, time marches on.

If nothing else, we simply get used to being alive.

No matter what else, we have love. Always love.

When journalists come to interview me, it's a part of my life that is exhibited, as if pieces of clothing are being taken off one by one. But it's not very important really.

A scattered dream that's like a far-off memory... a far-off memory that's like a scattered dream. I want to line the pieces up... yours and mine.

I just love listening to the laughter.
