Unfortunately I do not know enough on the topic myself however I have read on a number of occasions that "Global Warming" is a hoax - these days I don't know who to believe!

I believe that what has been happening is that surface meltwater has not refrozen, but rather cut down through the glacier to its base, lubricating the ice-rock interface and increasing the rate of flow into the ocean. Computer models had not taken this new observation into account, and will probably not until the phenomenon is better understood.

Should this be of concern - yes. This phenomenon couldl increase the rate of destruction of the glaciers, both in Greenland and Antarctica. If the feedback loops are +ve, then the deline of the ice sheets and the rise of sea level will occur that much earlier.

On a related note, see this point about the possible sudden decline in arctic sea ice in mid-century.

In a book written in the early 20th century, called "Arctic Riviera", there is a map with this island clearly delineated. Explain that gulible warming nuts.
