CLIMATE change has been the biggest concern for a whole generation. Now, however, a brilliant scientist has come up with proof that man is not to blame - and no problem exists.
Fill your tank with petrol, book another holiday, turn that patio heater up to 11 and breathe a deep sigh of relief: the theory that humans are responsible for global warming is as good as dead, thanks to an amazing new discovery by one of America’s top meteorologists.
In his new bestseller The Great Global Warming Blunder, former senior NASA climate scientist Dr Roy Spencer demonstrates that all those scary computer-modelled predictions of man-made eco doom have been based on a fundamental misconception of how climate works.
Climate change, he shows, is an almost entirely natural process on which human influence is negligible.
Of course, sceptics have been making this point for years, arguing that the quantities of carbon dioxide (CO2) produced by man are so tiny that even if they were to double there would still be no dangerous Anthropogenic Global Warming (AGW).
What they have been unable to answer convincingly until now, though, is the alarmists’ counterargument that CO2 emissions are exaggerated by “positive feedbacks”.
One type of positive feedback often cited by alarmists is cloud cover. When CO2 causes the world to warm, they argue, it reduces the number of clouds. Clouds are what help protect our planet from the burning heat of the sun, by reflecting solar radiation.
So even if the effect on climate of CO2 is relatively small, the potential knock-on effect is vast. This is why the predictions of temperature rises made by the Intergovernmental Panel On Climate Change (IPCC) assessment reports are so large and terrifying.
But according to Spencer, these alarmists have got completely the wrong end of the stick. The mistake they have made is to confuse cause with effect. It’s not man-made global warming that is causing cloud cover to grow thinner, leading to a spiral of ever-rising temperatures. Rather, it’s natural variations in cloud cover that are helping to cause global warming.
The implications of this are enormous. Not only does it mean that the billions of pounds of taxpayers’ money which have been pumped into proving the connection between CO2 and climate change have been utterly wasted but it also means that the climate policy of most of the world’s leading industrial nations is based on a total lie.
According to estimates by the International Energy Agency it will cost the world at least $45trillion to deal with AGW. Under the Climate Act, Britain is committed to spending a whopping £18billion a year combatting the effects of Climate Change. Most of this will go on attempting to reduce our output of CO2 – a gas which Spencer points out is not merely harmless but positively beneficial.
“The public debate over carbon dioxide needs to be reframed. Instead of asking ‘By how much should we cut back our CO2 emissions?’ we should ask ‘Is there any compelling reason to reduce CO2 emissions at all?’” says Spencer, who believes, “More atmospheric carbon dioxide might be good for life on Earth.”
This doesn’t mean that Spencer is a global warming “denier”. In fact all the evidence tells him that temperatures in the past 100 years or so have risen. Where he differs from alarmists such as US environmental activist Al Gore and NASA’s fearmonger-in-chief Dr James Hansen is in his understanding of the cause. They want to blame man; Spencer says it’s down to Mother Nature.
As the world’s greatest expert on satellite temperature monitoring, Spencer has access to the most accurate climate data yet collected.What his observations have shown him is that, yes, there has definitely been 0.7C of global warming since the beginning of the 20th century, but that three quarters of this was caused by an entirely natural process called the Pacific Decadal Oscillation (PDO).
