Abstract Late Pliocene and Early Pleistocene epochs 3.6 to 0.8 million years ago1 had climates resembling those forecasted under future warming2. Palaeoclimatic records show strong polar amplification with mean annual temperatures of 11–19 °C above contemporary values3,4. The biological communities inhabiting the Arctic during this time remain poorly known because fossils are rare5.

Correction to: Nature https://doi.org/10.1038/s41586-021-04016-x Published online 20 October 2021 In the version of this article initially published, there were mismatches between sample ID and the data in the second tag “damage” for Supplementary Data 6: Animal distribution & DNA damage. This occurred through reformatting in manuscript preparation and does not affect the rest of the paper. The corrected table has been uploaded to the HTML version of the article.
