Global reduction of snow cover in ski areas under climate change

S6 Fig. Australian Alps with ski areas and an underlying elevation layer (grey). Colouring indicates the percent change in annual snow cover days in each ski area in the future 2071– 2100 compared to historical (1981–2010) snow cover days under very high emissions (SSP5- 8.5) scenario. (TIF) S7 Fig. Japanese Alps with ski areas and an underlying elevation layer (grey). Colouring indicates the percent change in annual snow cover days in each ski area in the future 2071– 2100 compared to historical (1981–2010) snow cover days under very high emissions (SSP5- 8.5) scenario. (TIF) S8 Fig. Southern Alps with ski areas and an underlying elevation layer (grey). Colouring indicates the percent change in annual snow cover days in each ski area in the future 2071– 2100 compared to historical (1981–2010) snow cover days under very high emissions (SSP5- 8.5) scenario. (TIF) S9 Fig. Rocky Mountains with ski areas and an underlying elevation layer (grey). Colouring indicates the percent change in annual snow cover days in each ski area in the future 2071– 2100 compared to historical (1981–2010) snow cover days under very high emissions (SSP5- 8.5) scenario. (TIF) S10 Fig. European Alps with ski areas and an underlying elevation layer (grey). Colouring indicates the percent change in annual snow cover days in each ski area in the future 2071– 2100 compared to historical (1981–2010) snow cover days under high emissions (SSP3-7.0) scenario.
