Greenland Ice Sheet: "Starting to Slip" youtube/watch?v=qkpFNteryX8 See also: neven1.typepad/blog/2013/07/-greenland-ice-sheet-starting-to-slip.html robertscribbler.wordpress/2013/08/01/greenland-ice-sheet-slipping-under-hottest-temperatures-ever-recorded/ robertscribbler.wordpress/2013/07/30/global-warming-rolls-climate-dice-yet-again-high-amplitude-jet-stream-wave-brings-late-july-melt-surge-to-greenland/ And this from NSIDC: Dry cold snow is the most reflective naturally occurring land cover type on Earth, with albedos as high as 0.95, but as melting begins, this drops to 0.70, and continues to drop with increased melt. Very wet snow has an albedo of 0.6 to 0.5, and exposed ice can be as low as 0.3. This darkening of a snow surface with the onset and progression of melt leads to an important climate feedback. With warm conditions, melting and darker snow leads to more sunlight absorbed by the snow, leading to further melting and darkening. from: nsidc.org/greenland-today/
