On a related note: in the department of nuclear mea culpas, here's Mark Lynas in The Economist:
I entirely understand the arguments espoused by anti-nuclear campaigners, especially because I used to make them myself for many years. Personally I am embarrassed not that I changed my mind on nuclear, but that it took me so long to do so. I ignored overwhelming scientific evidence that nuclear is far safer than most people suppose, and in the process insisted on solutions to global warming which are neither technically feasible nor politically realistic. I would like to apologise for that.
Back to the Helen & George show and for them, perhaps the behind the scenes version.
