“To me the analogy [to climate change] is… doctors worry a lot about cholesterol. And if you go to the doctor, and the doctor says “oh, your life would be happier if you ate a different diet and exercised” people pay no attention.”

Ice in the West Antarctic and over Greenland, i.e., ice that’s over a rock at the moment, that will raise the level of the sea as it slides into the ocean, putting at risk everyone and everything that lives on the coasts, and that includes an enormous percentage of the world’s people.

We have built a greenhouse, a human greenhouse, where once there bloomed a sweet and wild garden.

Everything that the administration has done has been counterproductive.

My guess is that liberating the fossil fuel industry to frack anywhere they want will drive down the rate at which we’re converting to sun and wind. And it’s entirely a rate problem at this point.

Renewable energy is far more labor-intensive than fossil fuel production.

But tolerance by itself can be a cover for moral laziness.

I’m probably the wrong person to ask. My partner in much of this work [climate movement], who really came up with the divestment campaign with me, Naomi Klein, I think has written powerfully about this.

[Barack Obama] done some good things, he’s done a couple of bad things. He’s obsessed with this all of the above energy policy and… lots and lots of drilling in the States, so he’s been weak on it.

What makes us different? We’re the creature that can decide not to do something that we are capable of doing.

Probably more than anything else, the place that we really see the effects of the power of even the relatively mild temperature increases so far is in the melting of everything frozen on the planet.

The movers and shakers on our planet, aren’t the billionaires and generals, they are the incredible numbers of people around the world filled with love for neighbor and for the earth who are resisting, remaking, restoring, renewing and revitalising.

If you were running a solar company you may be okay – you may be able to keep growing. The question for physics is: Can you grow fast enough to begin to catch up with the damage?

I think we need to think of lots of ways to communicate. And we tried some at 350. We organised what they called the largest art project in the planet’s history. We do a lot with art and music and things.

We’ve been in lots of places that I suppose, by Oxford standards, would be considered illiterate, but everyone’s completely conversant with the idea that here is a number, and that number is above it, and that’s too high. It’s not a very complicated idea.

In the States, I think, the syllogism goes like this: ‘free markets solve all problems. Free markets aren’t solving global warming, QED global warming is not a problem’. It’s not a very good syllogism but it’s emotionally comforting if you’re in that world.

The ability to write compelling emails may be the single most useful talent an organizer can possess.

You’d have to be pretty hard-nosed not to feel some sympathy for the guy [Doctor Strange].

[Doctor Strange] gets scraped off the floor and then thrown right down to hell again and then slowly pulls himself back up.

I think it’s fair to say that, yeah, I’m playing Doctor Strange, I get there.

I’m aware of [Doctor Strange] place within the comic pantheon of it all, the Marvelverse, but I don’t email saying, “When are we doing next film?” I’m excited to see.

Doctor Strange is an origin story so there’s a certain room for me improving as well as the character improving.

I agree, the world would be a better place if doctors were less enthusiastic about adopting very new drugs.

My dad is a doctor, a professor of psychiatry, and my mum is a psychotherapist.

The clever people at CERN are smashing particles together in the hope that Doctor Who will turn up and tell them to stop
