But to all this deflation of the bubble our political class in Britain remains quite impervious. Our governments in London and Brussels charge on with completely unreal and damaging policies which increasingly look as much of a shambles as the warming scare which inspired them. Scarcely a single politician dares question the Climate Change Act, by far the most expensive law in history, which commits Britain, uniquely in the world, to reducing its CO2 emissions by 80 per cent in 40 years. By the Government's own estimates, this will cost up to £18 billion a year. Any hope that we could begin to meet such a target without closing down most of our economy is as fanciful as the idea that we can meet our EU commitment to generate 30 per cent of our electricity by 2020 from "renewable" sources, such as wind and solar.
