“The real negotiation is between humans on the one hand and chemistry and physics on the other. And chemistry and physics, unfortunately, don’t bargain.”

Where people aren’t as deeply reliant on fossil fuel as in the United States, it’s far easier for them to imagine change on this scale. When you go to Europe, they’re much more ready. They use half the amount of energy per capita that we use. They can imagine using less than that. They see the benefits. They’re ready to go.

If we continue to think of ourselves mostly as consumers, it’s going to be very hard to bring our environmental troubles under control. But it’s also going to be very hard to live the rounded and joyful lives that could be ours. This is a subversive volume in all the best ways!

We’re going to need that kind of movement, because the fossil fuel industry is a sprawling adversary – at work everywhere, its tentacles in everybody’s politics, invulnerable, I think, to direct frontal assault, but probably more brittle than it guesses if we come at it from all sides.

Especially in recent years, the more and more we understand what we are doing, the more we have the science to tell us what we’re doing, the fact that we continue to do it without taking steps to address it strikes me as, among many other things, irreverent in an extreme.

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?

Like thousands of other boys, I had a little chemical laboratory in our cellar and think that some of our friends thought me a bit crazy.

The whole art of making experiments in chemistry is founded on the principle: we must always suppose an exact equality or equation between the principles of the body examined and those of the products of its analysis.

Perhaps; some day the precision of the data will be brought so far that the mathematician will be able to calculate at his desk the outcome of any chemical combination, in the same way, so to speak, as he calculates the motions of celestial bodies.

Well, I see I am not designed to the finding out the Philosophers Stone, I have been so unlucky in my first attempts in chemistry.

Sulfur, when burning, absorbs oxygen gas; the resulting acid is considerably heavier than the sulfur burned; its weight is equal to the sum of weights of the sulfur burned and the oxygen absorbed.

Deep breathing changes the chemistry of the body by bringing oxygen into the tissue.

Every season, really, has their own chemistry.

What I Thought was love, was really just lust-electrical chemistry, no emotional availability.
