Correction to: Nature Geoscience, published online 9 May 2022.

In the version of this article originally published, the first sentence of the Fig. 1 caption should have read “a,b, The Deccan Traps and Cretaceous–Palaeogene (K/Pg) global warming (a) and Columbia River Basalt Group–Miocene Climate Optimum (b)” rather than “a,b, The Deccan Traps (a) and CRBG–MCO (b) Cretaceous–Palaeogene (K/Pg) global warming” as originally presented. Further, the last sentence of the Fig. 4 caption should have referred readers to the Methods section rather than Supplementary Information. The changes have been made in the HTML and PDF versions of the article.
