The evidence for human-made climate change is overwhelming.

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.

People who have had little self-reflection live life in a huge reality blind-spot.

Philosophy should make clear and delimit sharply the thoughts which otherwise are, as it were, opaque and blurred.

I really wouldn't want to live in America. I found New York claustrophobic and dirty. I missed England when I was there, simple things like smells and the British sense of humor.

Take a look at my face, I am the future.

I think audiences deserve the benefit of the doubt. I prefer to be surprised by them rather then just assume they'll react negatively to any new idea.

I'm in awe of people out there who deal with Alzheimer's, because they have to deal with death 10 times over, year after year.

Isn't there any other part of the matzo you can eat?

A thing is not necessarily true because badly uttered, nor false because spoken magnificently.

Instead of wondering when your next vacation is, maybe you should set up a life you don't need to escape from.

By banishing doubt and trusting your intuitive feelings, you clear a space for the power of intention to flow through.
