Global warming will cause a substantial reduction in snow cover in the world's seven main ski regions by the end of the century. Mountain resorts in the southern hemisphere will be even more severely affected.

Minus 78% of snow days in the Australian Alps; minus 51% for the Southern Alps in New Zealand. Andes, Latin America, by 2070-2100, with minus 43% in the Andes. The closer ski slopes are to the coast or in low or medium mountains, the more they will be affected.
