More action from the flat earthers. A recent monograph by Christopher Monkton, an aristo who apparently dabbles in Atmospheric physics, questioned the current model of climate change and went on to cast aspersions on it. George Monbiot shows why it is that much crap. From the article :
The author of this "research article" is Christopher Monckton, otherwise known as Viscount Monckton of Brenchley. He has a degree in classics and a diploma in journalism and, as far as I can tell, no further qualifications. But he is confident enough to maintain that - by contrast to all those charlatans and amateurs who wrote the reports produced by the UN's Intergovernmental Panel on Climate Change - he is publishing "the truth".
The warming effects of carbon dioxide, Lord Monckton claims, have been exaggerated, distorted and made up altogether. One example of the outrageous fraud the UN body has committed is the elimination from its temperature graphs of the "medieval warm period", which, he claims, was "real, global and up to 3C warmer than now". He runs two graphs side by side, one of which shows the temperature record over the past 1,000 years as rendered by the UN panel, and the other purporting to show real temperatures over the same period.
The world was so hot 600 years ago, he maintains, that "there was little ice at the North Pole: a Chinese naval squadron sailed right round the Arctic in 1421 and found none". By contrast the planet is currently much cooler than climate scientists predicted. In 1988, for example, the world's most celebrated climatologist, James Hansen of Nasa, "told the US Congress that temperature would rise 0.3C by the end of the century (it rose 0.1C), and that sea level would rise several feet (no, one inch)".
Most importantly, "the UN repealed a fundamental physical law", doubling the size of the constant (lambda) in the Stefan-Boltzmann equation. By assigning the wrong value to lambda, the UN's panel has exaggerated the sensitivity of the climate to extra carbon dioxide. Monckton's analysis looks impressive. It is nonsense from start to finish.
