ipcc’s alarmism

When future generations come to look back on the alarm over global warming that seized the world towards the end of the 20th century, much will puzzle them as to how such a scare could have arisen. They will wonder why there was such a panic over a 0.4 per cent rise in global temperatures between 1975 and 1998, when similar rises between 1860 and 1880 and 1910 and 1940 had given no cause for concern. They will see these modest rises as just part of a general warming that began at the start of the 19th century, as the world emerged from the Little Ice Age, when the Earth had grown cooler for 400 years.

Each time it would emerge just how shamelessly these Summaries had distorted the actual evidence, picking out the scary bits, which themselves often turned out not to have been based on proper science at all. The most glaring example was the IPCC’s 2007 report, which hit the headlines with those wildly alarmist predictions that the Himalayan glaciers might all be gone by 2035; that global warming could halve African crop yields by 2050; that droughts would destroy 40 per cent of the Amazon rainforest. Not until 2010 did some of us manage to show that each of these predictions, and many more, came not from genuine scientific studies but from scaremongering propaganda produced by green activists and lobby groups (shown by one exhaustive analysis to make up nearly a third of all the IPCC’s sources).

This latest report has aroused markedly less excitement than did its hysterical predecessor in 2007. They have cried wolf once too often. The only people still being wholly taken in, it seems – apart from the usual suspects in the media – are all those mindless politicians still babbling on about how in Paris next year they are finally going to get that great global agreement which, if only we put up enough wind farms and taxes, will somehow enable us to stop the climate changing.
They can dream on. But alas, the rest of us must still pay the price for their dreams.
