Sierra Nevada is left without a 'name' on its 25th anniversary: the snow goes from 343 centimeters to 60. Of the 111 skiable kilometers, if 84 were used in 2010, last year it was 45.2.
The deposition of Saharan dust - the so-called haze - in the natural space has gone from 17 micrograms per cubic meter to 24 since 1980. At this climatic rate there will come a time when not even artificial snow will be able to cover the slopes.
