Earth got its hottest year on record in 2023. Based on data from Berkeley Earth, John Muyskens and Niko Kommenda, for The Washington Post, focused on the geographic areas that experienced the biggest jumps.

The Post has mapped the regions that saw the largest temperature anomalies in 2023 — places that have warmed so fast that the climate is already testing the limits of human infrastructure and the ability of the natural world to cope.
