"The chief defence offered by the warmists to all those revelations centred on the IPCC's last 2007 report is that they were only a few marginal mistakes scattered through a vast, 3,000-page document. OK, they say, it might have been wrong to predict that the Himalayan glaciers would melt by 2035; that global warming was about to destroy 40 per cent of the Amazon rainforest and cut African crop yields by 50 per cent; that sea levels were rising dangerously; that hurricanes, droughts and other "extreme weather events" were getting worse. These were a handful of isolated errors in a massive report; behind them the mighty edifice of global warming orthodoxy remains unscathed. The "science is settled", the "consensus" is intact.And yet still I meet people who 'believe' that Global Warming is settled science and that I am at best a sceptic at worst an evil denier.
But this completely misses the point. Put the errors together and it can be seen that one after another they tick off all the central, iconic issues of the entire global warming saga. Apart from those non-vanishing polar bears, no fears of climate change have been played on more insistently than these: the destruction of Himalayan glaciers and Amazonian rainforest; famine in Africa; fast-rising sea levels; the threat of hurricanes, droughts, floods and heatwaves all becoming more frequent.
All these alarms were given special prominence in the IPCC's 2007 report and each of them has now been shown to be based, not on hard evidence, but on scare stories, derived not from proper scientists but from environmental activists. Those glaciers are not vanishing; the damage to the rainforest is not from climate change but logging and agriculture; African crop yields are more likely to increase than diminish; the modest rise in sea levels is slowing not accelerating; hurricane activity is lower than it was 60 years ago; droughts were more frequent in the past; there has been no increase in floods or heatwaves.
Furthermore, it has also emerged in almost every case that the decision to include these scare stories rather than hard scientific evidence was deliberate. As several IPCC scientists have pointed out about the scare over Himalayan glaciers, for instance, those responsible for including it were well aware that proper science said something quite different. But it was inserted nevertheless – because that was the story wanted by those in charge.
...
In other words, in crucial respects the IPCC's 2007 report was no more than reckless propaganda, designed to panic the world's politicians into agreeing at Copenhagen in 2009 that we should all pay by far the largest single bill ever presented to the human race, amounting to tens of trillions of dollars. And as we know, faced with the prospect of this financial and economic abyss, December's Copenhagen conference ended in shambles, with virtually nothing agreed.
...
Almost as revealing as the leaked documents themselves, however, was the recent interview given to the BBC by the CRU's suspended director, Dr Phil Jones, who has played a central role in the global warming scare for 20 years, not least as custodian of the most prestigious of the four global temperature records relied on by the IPCC. In his interview Jones seemed to be chucking overboard one key prop of warmest faith after another, as he admitted that the world might have been hotter during the Medieval Warm Period 1,000 years ago than it is today, that before any rise in CO2 levels temperatures rose faster between 1860 and 1880 than they have done in the past 30 years, and that in the past decade their trend has been falling rather than rising.
