Ice, ice, maybe: Snow and ice melting at record speed


Grist

You may have noticed it’s been a hot summer so far. June temperatures were above average across the world, and both NASA and NOAA ranked the month among the top five warmest since record keeping began in the late 1800s.

Not surprisingly, snow extent in the Northern Hemisphere was at its third-lowest on record by June. But what makes the current paltry snow cover more significant is the fact that, just a few months ago, the Northern Hemisphere was unusually snowy — April 2013 had the ninth-highest snow extent since 1967. A month later, half that snow had melted away. The Washington Post reports:

“This is likely one of the most rapid shifts in near opposite extremes on record, if not the largest from April to May,” said climatologist David Robinson, who runs Rutgers University Global Snow Lab.

The snow extent shrunk from 12.4 million square miles to…

Mount Everest to be Given a Clean Up


The world’s highest mountain, Mount Everest, is to be given a clean up. Everest, which was first climbed by Edmund Hillary in 1953, has become something of a garbage tip. Everything from climbers rubbish to dead bodies has been left on the mountain. Now a Nepalese expedition made up of twenty Sherpa mountaineers and eleven support crew is seeking to remove some of the garbage left behind since that first ascent.

The government of Nepal wants to clean up the popular tourist attraction, bringing down rubbish that includes old tents, climbing equipment and the odd body. Global warming has led to much of the rubbish (and several bodies) no longer being covered by snow and ice.

Over 300 people have been killed attempting the climb to the top of the world, the Mount Everest summit.
