With Tony Blair launching his own plan to save the world (groans), and the G8 leaders also unveiling their thoughts about global warming, this is a big week for environmental fanaticism. Whatever he or they offer, it will not be enough to quell the warmists’ semi-religious fervour. They are like medieval preachers, proclaiming to baying crowds that the end of the word is nigh.
Well, is it? There are two separate climate issues – the extent of global warming and the role that humanity plays in it. Some facts help. The famous 1996 report by the International Panel on Climate Change predicted serious global warming and blamed mankind. But, since then, the world has disobligingly stopped warming. And two years of global cooling erased nearly 30 years of recorded temperature rises. What was the worrying rise in temperature – so exciting for those whose computer models used the past to predict a grim future?
Given the margin of error associated with the old-style thermometers which were, until only recently, used to record temperatures, it should be stated thus: over the past 100 years, temperature has risen by 0.7C – plus or minus 1.3 degrees! The only importance the serious scientists can attach to such a figure is that less serious people think it meaningful. My own science teacher would have kept me in after school for saying this was a valuable figure.
But, as you will have noticed, it worked. The catastrophists piled in – some of whom had previously flourished warnings about global cooling. For some, any figure will do, especially when it gives them a media profile (and grants for research). Those who worry about facts should look at the findings of NASA (see the website), whose up-to-date and sophisticated global surveys throw such doubt on the warmists’ claims.
