Such research is now becoming urgent as regional climate change is already impacting upon areas of West Antarctica and the Antarctic Peninsula [30] and colonies in this region may already be affected by the consequent loss of sea ice [8].

The lag between decreases in sea ice extent during late summer and changes in the mid-latitude atmospheric circulation during other seasons (when the recent loss of sea ice is much smaller) needs to be reconciled with theory.

In its review, the Service paid particular attention to the impact to the species of the ongoing loss of sea ice in the walrus's range.

It is directly part of a feedback, in that more loss of sea ice causes more evaporation, which traps more heat, which melts more ice — one of the vicious cycles.

Francis, of Rutgers University, said the natural climate cycles will help determine where some of the extremes will occur this winter, but the record loss of sea ice raises the odds that extremes will take place.

But from an email conversation with Francis, Vavrus, and several other atmospheric scientists this week, it became clear that there may be more questions than answers at this point, given the large amount of natural variability that affects winter weather patterns, and the very short observational record of how the atmosphere responded to extreme losses of sea ice (only five winters of records since 2007).

This now leaves us with the likelihood of a rapid Arctic warming and consequent loss of sea ice.
