The long-discussed meeting between a group of climate scientists and Fellows of the Royal Society on the one side, and me and some colleagues from my think-tank, the Global Warming Policy Foundation on the other, has now at last taken place. It was held behind closed doors in a committee room at the House of Lords, the secrecy — no press present — at the insistence of the Royal Society Fellows, an insistence I find puzzling given the clear public interest in the issue of climate change in general and climate change policy in particular.
