I think the real concern about the Arctic ice melting is that it could, counterintuitively, lead to a new Ice Age. The reasoning is this: Europe, in spite of its high latitude is relatively temperate due to the warming currents flowing on the Atlantic seaboard there. These currents make a big circle between the North and South Atlantic (it gets warmed in the South). I forget all the details (read this in an Atlantic Monthly article a couple years ago), but basically, the reason this water is abnormally warm (and hence the reason Europe is abnormally warm compared to like lattitudes in Canada and Russia!) is that the water has a higher than average salinity at some point in the circuit, thereby creating a buffer zone which segregates the warm water and allows it to continue to flow back to Europe. The fear is, a melting of Arctic ice could reduce the salinity of the water, causing the currents which are warm to become cold. This could result in a colder Europe and lead to an Ice Age. So the theory goes, global warming will actually freeze the world, not burn it up.
