Klimaatangst verdampt, maar Britse politiek verkeert nog steeds in ontkenningsfase

A few years back, when the climate scare was still at its height, and it seemed the world might agree the Copenhagen Treaty and the US Congress might pass a "cap and trade" bill, it was claimed that the Chicago Exchange would be at the centre of a global market worth $10 trillion a year, and that "carbon" would be among the most valuable commodities on earth, worth more per ton than most metals. Today, after the collapse of Copenhagen and the cap and trade bill, the carbon price, at five cents a ton, is as low as it can get without being worthless.

Since then, despite a series of unconvincing attempts to clear the Climategate scientists, it has become clear that the 20-year-old climate scare is dying on its feet. The money draining away from the Chicago exchange speaks louder than all those inquiries – and the same point will be made obvious in a fortnight's time in Cancun, Mexico, as the UN attempts to salvage something from the wreckage at a conference that will draw scarcely a tenth of the numbers that met in Copenhagen.

None of this, of course, will do anything to save Britain from the looming crisis when the ageing nuclear and coal-fired power stations which supply 40 per cent of our current electricity needs are forced to close. The other night when it was very cold I checked to see how much of our electricity was, at that moment, coming from wind. The answer was 0.1 per cent, or a thousandth of all the power we were actually using to keep our homes lit and warm.

It appears that Chris Huhne, our Energy and Climate Change Secretary, is so obsessed with the half of his job relating to climate change that he can happily ignore the other half, to do with keeping the lights on. But Mr Huhne is far from alone. Not a single MP of any party has yet found the courage to mount a properly briefed challenge to all this lunacy. So what do we pay them for?
