Damien Green: Thom Yorke's music is listened to around the globe. His band, Radiohead, the voice of a whole generation. But as an environmentalist he fears he's struggling to make a himself heard.

Thom: "Stop pointing fingers! Everybody, stop pointing fingers. Yes, I'm a hypocrite! We're all hypocrites, because we've all been born into a carbon life. This is what we do. The structure of our existence is based upon expending energy using that. So we are ALL hypocrites."

Damien: Since the singer launched Friends of the Earth's "Just Ask" campaign, pressuring MPs for tougher environmental laws, ITV News has found its own evidence on climate change: the devastation of forests in Brazil, the retreating glaciers in the arctic circle, and the destruction of coral reefs. Yorke believes global warming has now gone from scientific theory to established fact.

Thom: "When you're presented with the science, it's absolutely terrifying. Then you start to sort of, connect the dots in what happens in your day-to-day life. I mean, it's just going to take a long time. But a long time we don't have."

Damien: Campaigners want Britain to set an example to the developing world, with new laws setting real targets for cutting greenhouse gases. But how can Britain hold back a country like China, hungry for cars and consumer goods, coal and gas, and oil?

Thom: "Unless we address our own hypocrisy we are not in a position to tell them what to do, obviously. But also, we are in a position to develop the new technology."

Damien: Hundreds of MPs, including Yorke's, have backed tougher laws. He hopes the political climate is changing, too.

Thom: "That's the point when, hopefully, people of Britain are still asking questions about it in five, ten years' time. When their kids are growing up, and the weather's getting worse."
