So, the rainforest scare, like the Himalayan glaciers panic, is garbage. A further encouraging feature of this development is that genuine scientists are increasingly becoming emboldened to challenge the IPCC’s junk science: the Academy is beginning to reassert its integrity. AGW without withered rainforests is Hamlet without the prince. It was one of those emotive claims much invoked by priggish children in the voice-overs of nanny-state “green” commercials, lecturing their elders on the stewardship of the planet.
An even bigger tear-jerker was the plight of polar bears, bolstered by carefully cropped photographs of lonely bears stranded on fast-melting icebergs, doomed to extinction. That is the second brick that has fallen out of the IPCC wall. The official legend is that polar bears are threatened with extinction by global warming. The IUCN Polar Bear Specialist Group, which has bought into global warming in a big way, has claimed that, of the 19 sub-populations of polar bears (13 of them in Canada, home to 60 per cent of polar bears), eight are declining, three are stable, one is increasing and there is insufficient data on the remaining seven.
Of the eight allegedly declining populations, two of them, including Baffin Bay, are non-contentious: sceptics concede that the two sub-populations, representing 16.4 per cent of the bear population, are declining – but in both regions the temperatures have actually fallen, so warming is an irrelevant issue. H Sterling Burnett, senior fellow at the National Center for Policy Analysis, has pointed out that in two regions where the population is growing – the Bering Strait and the Chukchi Sea – air temperatures have risen. So polar bears appear to thrive on warming – as scientists claim they did during the Mediaeval Warm Period 1,000 years ago and the Holocene Climate Optimum 5,000-9,000 years ago.
