Richard Betts of UK Met Office: ‘Most climate scientists* do not subscribe to the 2 degrees ‘Dangerous Climate Change’ meme (I know I don’t). ‘Dangerous’ is a value judgement’
'The most solid evidence for something with serious global implications that might happen at 2 degrees is the possible passing of a key threshold for the Greenland ice sheet, but even then that's the lower limit and also would probably take centuries to take full effect. Other impacts like drought and crop failures are massively uncertain'
