Fig. 4: Glacier mass and dry-melt-season runoff projections for the seven relatively arid and strongly glaciated basins under the GFDL-ESM2M climate model.
From: Irreversible glacier change and trough water for centuries after overshooting 1.5 °C
a, Glacier mass relative to 2020 and glacier-area weighted basin-wide temperature changes to 2000–2019 (both 21-year averaged). b, Glacier runoff relative to 2000–2050 and respective precipitation relative to 2000–2019 (both from the three driest months in the melt season and 51-year averaged). For each basin, we give the glaciated area and the number of years with estimated trough water with the maximum difference (Δmax). We give the driest melt months in Supplementary Fig. 8. We only show here three scenarios to allow for a better comparison. The same illustration for only the melt components is in Supplementary Fig. 6. The map shows the outlines of the seven selected basins. All basins have an aridity index <2 (according to ref. 2) and are initially above 0.9% glaciated. The projected annual glacier runoff of all 60 glaciated basins is in Supplementary Figs. 3–5. Map from Natural Earth (https://www.naturalearthdata.com/).
