Climate change causes glacial river in Yukon to change direction

from CBC News…

Glacier retreated so much that its meltwater switched course, in an event not documented in modern times.

Climate change has caused the massive Kaskawulsh Glacier in the Yukon to retreat so much that its meltwater abruptly switched direction, in the first documented case of “river piracy” in modern times.

Instead of flowing into the Slims River and then north to the Bering Sea, the water has changed course and now flows south toward the Kaskawulsh River, the Gulf of Alaska and the Pacific Ocean, scientists have found.  Read more…

Ice Sheet Thickness from Satellite Observations

IceThicknessYet another exploration of how remote sensing by satellites is helping researchers learn more about what’s happening here on Earth. The beauty of it is that satellites work around the clock making images and taking measurements to degrees of accuracy we could never imagine in the past.

Put all those snapshots and measurements together over time and we end up with a reality far better than any model. This video shows quite well what is happening to ice in the Arctic and Antarctic: Ice Sheet Thickness from Satellite Observations – brought to you by the European Space Agency.
