Extended Data Fig. 3: Regional ROC curves during the summers of 2022-2024.

a-o, Relative operating characteristics (ROC) curves of exceeding the emergency threshold for lead times 3 (gray), 7 (red), 10 (green) and 15 (blue) days in different European regions during the summers of 2022 (a, d, g, j, m; panels in the left column), 2023 (b, e, h, k, n; panels in the middle column) and 2024 (c, f, i, l, o; panels in the right column). The emergency threshold corresponds to 75th centile of the daily regional distribution of heat-related mortality over the summers of 2022-2024.
