More glacier melt numbers

Posted a few links on SciGuy's blog about Himalayan glacier melt after some making-a-name-for-himself Texas State Climatologist pointed out an IPCC quirk. Big ff-ing deal. Ice is melting all over the Earth as the climate warms. This article lays it out:

Climate change: ice melting faster everywhere


In recent years, Himalayan glaciers have been retreating at rates ranging from 10 to 60 metres per year. As the glaciers disappear, the dry-season flows of river systems that depend on them may decrease by up to 70 percent, making them seasonal rivers. River systems at risk include the Yangtze, Yellow, Indus, Ganges, and Brahmaputra.

The Andes, home to 90 percent of the world's tropical glaciers, are also experiencing rapid melt and a shrinking water supply: between the early 1970s and 2006, Peruvian and Bolivian glaciers lost about one third of their surface area.

In Peru, glacier and snow melt provides 80 percent of the fresh water, used not only for drinking but also for hydroelectricity, which supplies more than 80 percent of the country's power.


This is going to constitute a Major Problem, folks.
