Fig. 2: Climate and glacier changes under the RCP2.6 and RCP8.5 scenarios for the 100 selected glaciers.
From: Less water from glaciers during future megadroughts in the Southern Andes
a anomaly of annual mean air temperature, b anomaly of annual total precipitation, c changes in total glacier volume, d cumulative glacier mass balance, e anomaly of total glacier runoff, and f anomaly of summer glacier runoff. Anomalies of air temperature, precipitation and glacier runoff are relative to the reference period (2000–2009, REF). Changes in glacier and mass balance are relative to their initial values (year 2000). The continuous lines and the shaded areas in red and blue represent the averages and the ranges provided by the sample of GCMs under each scenario, respectively. Black lines represent the model results for the reference (REF) and the Chilean megadrought (CMD) periods (2000–2019). The grey shaded areas indicate the Chilean megadrought (2010-2019) and the future period in which we search for 10-year megadroughts (see next section). In Supplementary Fig. 16 we present the same changes presented here using absolute values. A summary of the average values for the 2090-2099 decade is presented in Supplementary Table 1.
