Correction to: Nature Climate Change https://doi.org/10.1038/s41558-017-0009-5, published online 20 November 2017.

In the version of this Letter originally published, the increments on the y axis of Fig. 3 were incorrectly labelled as ‘0.0; 0.2; 0.2; 0.3’; they should have read ‘0.0; 0.1; 0.2; 0.3’. This has now been corrected in all versions of the Letter.
