At last people are telling David Cameron that his bunny-hugging has the potential to cause extreme economic and political damage.
Although I risk immediately being branded mentally defective for saying so, I am not convinced by the notion of man-made global warming. My lack of conviction, I would be the first to admit, is based on nothing resembling great scientific understanding: I have not so much as an O-level in physics or chemistry. All I do know is this: that the planet has heated up and cooled down at various points in its history without any help from factories, lorries or a beef-farming industry. Other planets have done, and continue to do, the same: I am still waiting for an answer to John Redwood's excellent point that the surface temperature of Mars has risen over the past few decades "and they are still looking for the 4x4s that did it". I therefore remain, in the phrase of Sir Antony Jay, the creator of Yes Minister, a firm thermosceptic.
Various other factors have contributed to an acceleration of my thermoscepticism. There was Lord Lawson's detailed and challenging riposte to the Stern report. There is Christopher Booker's superb recent book, The Real Global Warming Disaster, which I recommend that you all read. There is the hectoring tone of the BBC on the question, where any contributor to any programme who appears to be a thermo-denier is treated with incredulity and astonishment.
