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 addition, we can now read in shocking detail the truth of the outrageous efforts made to ensure that the same 2007 report was able to keep on board IPCC's most shameless stunt of all – the notorious "hockey stick" graph purporting to show that in the late 20th century, temperatures had been hurtling up to unprecedented levels. This was deemed necessary because, after the graph was made the centrepiece of the IPCC's 2001 report, it had been exposed as no more than a statistical illusion. (For a full account see Andrew Montford's The Hockey Stick Illusion, and also my own book The Real Global Warming Disaster.)
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. Read more.
