We know that Arctic sea ice extent has been at relatively low levels this past winter. However, most of the deficit has been on the periphery, mainly in the Barents Sea, or way outside the Arctic anyway, areas which would soon melt away anyway.
The natural consequence of this reduced ice coverage is that enormous amounts of heat have been escaping from the oceans during the Arctic winter, a phenomenon that is part of the Earth’s thermostat.
However, largely as a consequence of this low ice extent, the spring melt has been slow to arrive.
