World stubbornly refuses to warm

Two decades ago Al Gore predicted that by now we would all be in the grip of runaway global warming. So it was delightfully appropriate that his hometown of Nashville, Tennessee, in enjoying the coolest July in its history, breaking a record established in 1877. At the same time large parts of Argentina have been swept by severe blizzards last week, on a scale never experienced before. So far Gore’s predictions have proved so wildly wrong – along with those of the Met Office’s £33 million computer model which forecast that we should now be enjoying a “barbecue summer” and that 2009 would be one of “the five warmest years ever”. In response, the propaganda machine has had to work overtime to maintain what is threatening to become the most expensive fiction in history. The two official sources of satellite data on global temperatures, lately announced that June temperatures had again fallen, to their average level for the month over the 30 years since satellite data began. By contrast, the Goddard Institute for Space Studies, run by Gore’s closest ally and scientific adviser, James Hansen announced that in that single month the world had warmed by a staggering 0.63 degrees C, more than its net warming for the entire 20th century. In the past few years, Dr Hansen’s temperature record has become ever more eccentric, often wildly at odds with the other three officially recognised data sources, all of which showed a dramatic drop in temperatures in 2007 leading to markedly cooler summers and two of the coldest and snowiest winters the world has known for decades. All this has equally made nonsense of the predictions of the computer models that the UN’s Intergovernmental Panel on Climate Change relies on, which are programmed to assume that temperatures should soar in line with rising levels of greenhouse gases. Carbon dioxide levels continue to rise, but temperatures (apart from those revealed by Dr Hansen) have seriously parted company with them. This has not prevented the propaganda machine’s media groupies continuing to peddle a daily stream of stories about how in all directions global warming is already affecting the world for the worse. Soay sheep are shrinking in size (I am sure they’ve really noticed the global warming up on that bleak Scottish islet). Even a report on the record number of Painted Lady butterflies in Britain this summer cannot resist ending with a ritual forecast that many butterfly species will soon disappear because of “climate change”. Meanwhile even America’s foremost pro-warmist, Dr Michael Mann of “hockey stick” fame, concedes that global temperatures are not only declining but are likely to continue to do so for at least another decade – after which, of course, they will leap up again higher than ever. None of this is proving of much assistance to the politicians still desperately hoping to reach agreement on a new climate treaty in Copenhagen in December.
