Extended Data Fig. 3: Simulated multi-model mean changes in different MHW characteristics exceeding the preindustrial 99th percentile since preindustrial times for different global warming levels.

a–l, Changes in the maximum annual intensity (a, d, g, j), annual mean duration (b, e, h, k) and annual cumulative mean intensity (c, f, i, l) of MHWs for global warming of 1 °C (a–c), 1.5 °C (d–f), 2 °C (g–i) and 3.5 °C (j–l). The black contours highlight the pattern of changes.
