Two more quick stories coming through today about the state of glaciers melting due to climate change: 1) It's been confirmed that Bolivia's Chacaltaya glacier melted away six years earlier than expected, and 2) Scientific American has some interesting video of a Himalayan glacier melting from within, not just at the edges, as documented by the pace of a nearby lake filling.
Here's the video of the Ngozumpa Glacier in Nepal purging meltwater from within:
As for Chacaltaya, TreeHugger, along with everyone else that the glacier fully melted away back in 2009—and doomed the world's highest ski run at the same time. Now Skeptical Science reports that the World Glacier Monitoring Service has confirmed what the naked eye already saw. But that's not the point, Skeptical Science notes.
The confirmation was announced in the Glacier Mass Balance Bulletin 08/09, which is really how we ought to be determining the effect of climate change on glaciers, not just the spectacular retreat of any given glacier.
In short, the WGMS shows that, as of 2009, 90% of the 136 glaciers around the world accounted for in the survey are in fact losing mass.
