FRESH doubt has been cast on evidence for global warming following the discovery that a key method of measuring temperature change has exaggerated the warming rate by almost 40 per cent.
Studies of temperature records dating back more than a century have seemed to indicate a rise in global temperature of around 0.5 ° C, with much of it occurring since the late 1970s. This has led many scientists to believe that global warming is under way, with the finger of blame usually pointed at man-made pollution such as carbon dioxide.
Research should not be dismissed by sceptics
Scientists' discoveries give lie to doom-monger predictions
Now an international team of scientists, including researchers from the Met Office in Bracknell, Berkshire, has found serious discrepancies in these temperature measurements, suggesting that the amount of global warming is much less than previously believed.
