Mark Lynas is a seriously well informed person. While many of us use broad phrases like 'climate change impact', he has very precise knowledge.

To show that climate change isn't something that's going to happen but is already here, he visited many parts of the world already affected, reporting it in the book High Tide: Notes From A Warming World.

As the global temperature is likely to rise up to six degrees this century, he wrote Six Degrees. Six chapters, each detailing the results of extensive research on what the next degree of warming is likely to cause.

He's also a prolific writer of articles, and has spoken out in favour of radical activists such as the Camp for Climate Action.

So it was surprising when, in May 2005, he came out as a convert to the idea of nuclear power using some questionable lines of thinking.
