Correction to: Nature Climate Change, published online 30 November 2017.

In the version of this Perspective originally published, Fig. 1 incorrectly had two entries of ‘Reduced rate of sea-level rise by 20% by 2050’; the first entry (row 2, column 3) should instead have read ‘Reduced disruption of weather patterns’. This has now been corrected in the online versions of the Perspective.
