Christopher Booker's guest post at EU Referendum is well worth a read. He discusses Margaret Thatcher's personal climate change journey from fearmonger to sceptic and the attempts by establishment figures such as William Waldegrave to draw a veil over her awakening.
I don't know whether Lord Waldegrave ever read the nine pages of her book, headed "Hot air and global warming", and I very much doubt whether he has ever read anything written by Prof. Lindzen - let alone much else written in recent years by those scores of other eminent scientists and other experts who have questioned every one of the a priori assumptions used to promote the belief in CO2-induced global warming.
Much easier, in deference to the fashionable orthodoxy, just to imply that Lady Thatcher's later views were no more than the senile ravings of an old woman in her retirement, and to place against them the ex cathedra pronouncements of his fellow-pillars of the establishment such as Lord May and Lord Rees, each carrying with him all the unimpeachable authority which goes with being a President of the Royal Society.
