Correction to: Nature Climate Change https://doi.org/10.1038/s41558-017-0064-y, published online 22 January 2018.

In the version of this Letter originally published, in Fig. 2, the labels for the yellow and green areas were swapped: the yellow areas should have been labelled ‘Global uncertainty zones’ and the green areas should have been labelled ‘Global safe zones’. This has now been corrected in the online versions of the Letter.
