Around 1985 the icy island started to thaw, and has continued apace ever since. Climate scientists have been alarmed by the speed of the melting, watching as glaciers recede and meltwater pools in lakes on top of the ice.Here are two views of the meltwater lakes they're talking about, from July 2002 and July 2008, on the 16th of the month. One of these drained suddenly in 2006, when some scientists happened to be on hand studying it, so it made big news. The pattern of lakes in 2002 and 2008 is very much the same, and it looks like the edge of the ice follows the same line very closely, so I don't know about "continuing apace". I can see getting worried about these lakes, though. They are obviously a potentially active agent of erosion. Are there more of them in the 2008 image?

Thank you for your post and the satellite map comparison. The type comparison that you ask is one that likely needs computer analysis to identify. The outward range of change one would expect would seem undetectable to the human eye.
