The surname of author V. Masson-Delmotte was misspelled as Masson-Demotte. In Table 1 of this Perspective, the ‘Source’ for ‘Label in Fig. 3’ entry 13 should be ref. 61 (not ref. 65). In addition, the x-axis labels of Fig. 3c were misplaced. Figure 1 shows the corrected panel and the original Perspective has been corrected online.
