The warmist whine
...They do sound like the plot of an Al Gore movie.
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.
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.
They also sound like the correction's page of a really botched story, and that is exactly what they are.
