Fig. 3: Relationship among global air temperature and labor losses.
From: Increased labor losses and decreased adaptation potential in a warmer world
Global-mean temperature anomalies (relative to the 2001–2020 mean) and global sums of heavy labor lost for the full 12-h workday (a) and for the coolest hour of the day (b) for 1979–2020 and with +1 °C, +2 °C, +3 °C, and +4 °C of additional global warming. Darker colors indicate higher warming levels. For future warming relationships, Coupled Modeling Intercomparison Project, Phase 6 (CMIP6) simplified Wet Bulb Globe Temperatures (sWBGT) warming patterns (Supplementary Fig. 5) are added to the 1979–2020 reanalysis-based sWBGT data for each global temperature change (+1 °C, +2 °C, +3 °C, +4 °C). Lines show best-fit regression lines for the given climate state (1979–2020, +1 °C, +2 °C, +3 °C, +4 °C), and the legend lists the slopes of these regression lines. Crosses mark global sums of heavy labor hours lost for individual years, with the year 2020 shown in a black cross.
