Correction to: Nature Geoscience, published online 21 July 2022.

In this article, the Fig. 1b legend labels “Non-peat-forming forest” (green shading) and “Savannah” (orange shading) were originally swapped in error. In addition, in Fig. 4b, the orange “2,750–3,500” legend was incorrectly shown as “2,750–3,000.”

The changes have been made to the HTML and PDF versions of the article.
