New study on previous IPCC projections vs. actual observations

New research from Cambridge University (UK) compared earlier sea level projections from the International Panel on Climate Change's 5th assessment with actual observations that were detailed in the 6th assessment.

The team focused on 2007 projections of future global sea level rise, the contribution to sea level rise from Greenland, Antarctica glaciers, thermal expansion and land water.

What they found was that these projections from 15 years ago were very good overall and within the ranges of uncertainty compared to the observed period from 2008 to 2018. See charts below.

From the charts above, the observed contribution to sea level rise from glaciers is running along the lower portion of the earlier AR5 projections.

The projections for sea level contribution from Greenland and Antarctica have been very accurate so far. Observed global sea level rise from 2008-2017 was also right in line with the 2007 projections.
