Well, first and foremost, it's not "record levels" of ice if there was a higher level just four years ago.
Secondly, if you're going to reference DMI, you might as well toss in this graph too:
Volume of ice is, at least in areas that are usually firmly frozen over, is usually viewed secondly to Ice Extent (i.e. the portion of the region with a certain concentration of ice). The reason being that, at least initially, results of warming causes ice to break off and float around rather that instantly melt. This is why the volume (concentration) of ice stays relatively consistent, at least initially.
And the SIE (Sea Ice Extent) has been dipping noticeably over the long term; well over two SDs away from where it was between 83-00, so this is almost certainly not a change due to any sort of random chance.
