"Unless we stop now, we will really doom the lives of our descendants. If we just go on for another 40 or 50 years faffing around, they'll have no chance at all, it'll be back to the Stone Age. There'll be people around still. But civilisation will go." James Lovelock, The Independent, 24 May. When James Lovelock calls for a massive expansion in nuclear power generation to ward off the worst effects of climate change, as he did in a front-page article in The Independent this week, you have to pay attention. The future may view him as the most important scientist of the twentieth century, and he is revered by the Green movement, which hates nuclear energy. But now he writes: "Every year that we continue burning carbon makes it worse for our descendants and for civilisation....I am a Green, and I entreat my friends in the movement to drop their wrongheaded objection to nuclear energy."
