Correction to: Nature Climate Change https://doi.org/10.1038/s41558-018-0127-8, published online 2 April 2018.

In the version of this Article originally published, the labels showing the degree of warming in panels c and h of Fig. 2 were incorrectly stated as ‘20 °C’; the correct labels are ‘2.0 °C’. These have now been amended in the online version.
