After climbers are hit by "a wave of snow 80 stories tall" on Mt. McKinley, the New York Times blames global warming

For Climbers, Risks Now Shift With Every Step - NYTimes.com

Sharper seasonal variations of ice and snow and temperature are being repeated all across the world from the Himalayas to the Andes, which scientists say are driven by a higher level of energy in the atmosphere from global warming. As a result, climbers have to think twice about what they might expect one year to the next, or even one day to the next, in places they might have climbed for decades.

On McKinley, the snows this year have been prodigious, and the four avalanche deaths have tied a record last seen in 1987.

As the crew of five inched down the tallest peak in North America early Thursday morning, a wave of snow 80 stories tall crashed over them, snapping the rope that kept the group connected and burying four of the climbers, said John Leonard, Denali National Park’s chief mountaineering ranger.

An avalanche dog and 10 rangers continued to search for bodies Saturday in debris and 2 feet of fresh snow...Mt. McKinley has some of the worst mountain weather in the world, Leonard said. Winds howl up to 80 mph. Temperatures frequently dip below minus 40.
