Politicians in Paris will try, if that’s not too kind a word, to find an agreement that will hold down temperature increases to 2 degrees C above pre-industrial levels [+2C].
Still too much, says James Hansen, of NASA (retired) and Columbia University, who has been warning us about this since 1981 or so:
• The last time Earth was +2C, 120,000 years ago, sea levels were 6-8 meters higher than today. 2 degrees would lock that in, the only question being how fast we would get there.
From today’s Guardian – NASA’s James Hansen talks to the UK government:

[…] Hansen met ministers in the UK government, which the Guardian previously revealed has secretly supported Canada’s position at the highest level.
From last Friday’s Guardian – the UK government couldn’t care less:
