How will global temperatures evolve over the next 20 years? The IPCC AR5 made an assessment that average global temperatures in the 2016-2035 period would likely be 0.3 – 0.7°C above the 1986-2005 average. Some climate scientists disagree with that assessment.
The first figure below shows the IPCC AR5 assessment (published in 2013), with the observed global temperature time-series updated. After a lengthy and useful discussion on twitter, Judith Curry confirmed her belief that the assessment should have been 0.2 – 0.6°C (second figure), which includes the possibility of global cooling inside the likely range (red hatching).
So, two views are now “on the record”. Any others?!
