I don't think the fossil fuel industry will listen, not until we build up a lot of pressure. I do think we can persuade some shareholders that they don't want to be involved in this enterprise.

Look - every time is the wrong time and the perfect time to have a kid, and you just do it when you can.

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.

We'll never get there if we let the climate crisis bloom unchecked, so for the moment the key is to organize, organize, organize!

By themselves, they are not enough; we also need to engage in political action.

Other thing we need to understand is that the financial power of the fossil fuel industry has so far prevented even any minor progress. They have a sweetheart deal unlike any other business on Earth: they're allowed to dispose of their waste for free, to use the atmosphere as an open sewer. And they will do all they can to defend that special privilege.

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.
