How green zealots gagged professor who dared to question global warming

Later the journal said it had rejected the paper because the reviewers questioned the paper’s methods.

But another journal turned it down without it even being sent out for peer review. Prof Bengtsson says this only normally happens if the editors believe the work is ‘trivial’ or ‘unimportant’.

Prof Bengtsson, 79, is one of the world’s most eminent climate scientists. Last week he was forced to step down from the council of the Global Warming Policy Foundation (GWPF), the sceptical think-tank set up by Lord Lawson.

He was accused by former friends and colleagues of ‘crossing into the deniers’ camp’.

Prof Bengtsson said the pressure was so great he had feared for his health. He said he had been stunned by the ‘emotional’ reaction to his joining the GWPF.
