As an undergraduate, I did maths and physics. That doesn't make me a scientist. So I try to read and understand and talk to scientists.

Meat is a wasteful use of water and creates a lot of greenhouse gases. It puts enormous pressure on the world's resources. A vegetarian diet is better.

What we are talking about is extended world war...People would move on a massive scale. Hundreds of millions, probably billions of people would have to move.

Climate change and global poverty are two sides of the same coin. Both challenges must be addressed together. If we fail on one, we will also fail on the other.

Climate change represents the greatest and widest-ranging market failure ever seen

There is still time to avoid the worst impacts of climate change, if we take strong action now.

The scientific evidence is now overwhelming: climate change presents very serious global risks, and it demands an urgent global response.

Adaptation is the only means to reduce the now-unavoidable costs of climate change over the next few decades

If you look at all the serious scientists in the world, there is no big disagreement on the basics of this...it would be absolute lunacy to act as if climate change is not occurring.

My father's generation's crisis was fighting fascism. Ours is fighting climate change. It is much harder because you can't see it, it is not an obvious threat. But the solution is in our hands.

Climate change is a result of the greatest market failure the world has seen...We risk damages on a scale larger than the two world wars of the last century.

If the goddess—and that would be me, by the way—is displeased, you’ll get bats in your hair and mice in your boots.

Be yourself, don't take anything from anyone, and never let them take you alive.

If I could take a punch like that, I might have been able to think up a name besides George for all my sons.

Have the strength to be an honest person.

I do not know of any environmental group in any country that does not view its government as an adversary.

Once in his life, every man is entitled to fall madly in love with a gorgeous redhead.

On Hollywood turning its back on him: I wasn't in the club. You see, I'm not going to be a stroker. I never have been all my life.

The wave does not need to die to become water. She is already water.

Cause if you’re happy in your head, then solitude is blessed, and alone is okay.

You always have to lie. I've been in plays that people don't enjoy and I pray that they lie to my face when I come outside.
