Analysis: ‘What could justify the increase in confidence from 90% to 95%, and it what sense has the evidence for human influence grown since AR4 was published in 2007?’

Analysis of key points UN IPCC report: 

‘It is extremely likely (95%) that human influence has been the dominant cause of the observed warming since the mid-20th century’
No best estimate of climate sensitivity, but a likely range given of 1.5 – 4.5C.  The low end  is slightly lower than it was in AR4 (2.0).
