Fig. 2: Rising fraction of birth cohorts facing unprecedented lifetime heatwave exposure.
From: Global emergence of unprecedented lifetime exposure to climate extremes

a, Box plots show the cohort fraction reaching ULE to heatwaves (CFheatwaves) for 1.5 °C (blue), 2.5 °C (gold) and 3.5 °C (red) pathways for global birth cohorts between 1960 and 2020 (middle line, median; box limits, upper and lower quartiles; whiskers, extend to the full range of the model ensemble). b, Bars show global cohort sizes in millions, with totals in grey and median numbers of people reaching ULE to heatwaves for 1.5 °C (blue), 2.5 °C (gold) and 3.5 °C (red) pathways. c–e, Maps display country-level CFheatwaves of the 2020 birth cohort for 1.5 °C (c), 2.5 °C (d) and 3.5 °C (e) pathways.
