It is predicted that half of the resorts in the Tyrolian Alps will not see cold enough conditions to remain viable by 2070, with only 15% able to survive past 2100, while US resorts may lose half their ski-season days by 2050. Around 30 cm of snow 70% of the time over a 100-day season is the baseline for a successful resort, but snow-season in the Swiss Alps has already dropped by 37 days since 1970, while average snowfall in the French Alps declined 64 cm from 1960 to 2005.
