Fig. 5: Country-level exposure to unprecedented heat (MAT ≥29 °C) at 2.7 °C and 1.5 °C global warming in a world of 9.5 billion people (around 2070 under SSP2).

a, Population exposed for the top 50 countries ranked under 2.7 °C global warming (dark blue) with exposure at 1.5 °C global warming overlaid (pale blue). Note the break in the x axis for the top two countries. b, Fraction of land area exposed for the top 50 countries (again ranked under 2.7 °C global warming with results for 1.5 °C global warming overlaid). The inset in a summarizes the total global exposure of countries, population and land area at the two levels of global warming, with results for all countries provided in Supplementary Data. UAE, United Arab Emirates; Neth. Antilles, Netherlands Antilles; Brit. Indian Ocean Terr., British Indian Ocean Territory.
