Correction to: Nature Climate Change https://doi.org/10.1038/s41558-020-0815-z, published online 29 June 2020.

In the version of the article initially published, there was an error in Fig. 1d: the third graph, now labelled “150 hPa height”, incorrectly read “500 hPa height”. This has been corrected in the HTML and PDF versions of the article.
