Tornado Alley (PROG)

[fuagf]

F6, Pine Island, glacier .. notes plus images .. thinning four times faster than 10 years ago .. surface rate dropping up to 16m a year .. surface down up to 90m since 1994 .. serious implications for sea-level rise .. British research in Geophysical Research Letters .. team led by Professor Duncan Wingham of University College London (UCL) .. calculations based on the rate of melting 15 years ago ice stream longevity adjusted from 600 years (calcs based on 15 yr old figures) to recent research 100 yrs .. loss rate fastest in centre, implications if continues glacier break-up could start to affect ice sheet further inland .. Professor Andrew Shepherd of Leeds University, centre melting would add about 3cm to global sea level .. (note: most of Bangladesh is 1m above sea level) .. NOTE: ice trapped behind it is about 20-30cm of sea level rise .. we don't really know what will happen as we destabilise or remove the middle of the glacier we don't know really know what's going to happen to the ice behind it .. unprecedented in this area .. known it's been out of balance for some time, "but nothing in the natural world is lost at an accelerating exponential rate like this glacier." .. large, multiple deep crevasses are sign parts of the glacier are moving rapidly .. West Antarctic .. 11-hour round-trip from Punta Arenas .. ice stream 20 miles wide, in places one mile, plus thick .. latest satellite data showing rate on surface drop level will add to the alarm among polar specialists.


Greenpeace, studying northwestern Greenland .. one, Professor Jason Box of Ohio State University, surprised by how little sea ice seen in the Nares Strait between Greenland and Canada .. set up time lapse cameras set up to monitor the massive Petermann glacier .. huge new cracks observed and expected a major part could break off imminently .. "The science community has been surprised by how sensitive these large glaciers are to climate warming. First it was the glaciers in south Greenland and now as we move further north in Greenland we find retreat at major glaciers. It's like removing a cork from a bottle."
