One of the world’s most eminent climate scientists – for several decades a warmist – has defected to the climate sceptic camp.
Lennart Bengtsson – a Swedish climatologist, meteorologist, former director of the Max Planck Institute for Meteorology in Hamburg and winner, in 2006, of the 51st IMO Prize of the World Meteorological Organization for his pioneering work in numerical weather prediction – is by some margin the most distinguished scientist to change sides.
For most of his career, he has been a prominent member of the warmist establishment, subscribing to all its articles of faith – up to and including the belief that Michael Mann’s Hockey Stick was a scientifically plausible assessment of the relationship between CO2 emissions and global mean temperature.
But this week, he signalled his move to the enemy camp by agreeing to join the advisory council of Britain’s Global Warming Policy Foundation (GWPF), the think tank created by the arch-sceptical former Chancellor Lord Lawson.
