Thanks for introducing this very topical issue! I have recently seen much discussion of this possible trend:
There are some suggestions that this may be from volcanic activity or related geological effects:
I see that one recurring issue is the idea of who has the rights to the resources of this region, especially (of course) the “Artic Oil” –

Arctic sea ice is in constant motion. It rides on the ocean, absorbing energy from the circumpolar weather systems. This movement causes a buildup of stress within the ice. Under enough stress, the ice cracks or buckles in a cataclysmic process that resembles the energy released in earthquakes. These continuous ice quakes result in open leads of water or mountainous ridges of broken, jumbled ice. These deformations, in turn, may have an effect on the thickness and durability of the arctic ice pack in the face of climate change...

Latest update about movement of glaciers in ocean
Since 1991, the western edge of Greenland's ice sheet has actually slowed its ocean-bound progress by 10%, say the team, who have studied the longest available record of ice and water flow in the region.
Greenland's mighty ice sheet has enough water locked away to raise global sea level 6.5 metres were it to melt. Each summer, vast lakes of meltwater form on its surface. The water seeps through cracks in the kilometer-thick ice to bedrock, where it acts as a lubricant. The sheet can move up to twice as fast in the summer, when meltwater is flowing, as when it is not.

Meltwater is rapidly increasing the tempo of glacial movements on the rim of the Greenland ice sheet. Over the long term, however, this process is interrupted as meltwater drains away via broad channels, as a result of which ice movement decreases once again. Ultimately, this is not a cause of accelerated sea level rise.
