The resulting enhanced loss of summer and winter sea ice resulted in feedbacks, associated with Arctic Amplification, which has raised Arctic air temperatures at a rate twice the global average.

Actually the argument makes more sense applied to the arctic sea ice — both in winter and summer, since it is at a much higher average latitude and therefore affects albedo much less.

Last winter, sea ice extent was on the low side, but the melting trajectory looks pretty average for the decade of the 2000's.

a Average sea ice concentration 1988 — 2007 for March (winter maximum) and September (summer minimum)(Source: http://nsidc.org/).

So, Thoman says, the sea - ice uptick is more of a statistical hiccup than a departure from this winter's consistently below - average Arctic sea - ice cover, based on more than three decades of observations.

Those dangers are now being dramatically demonstrated around the globe: drought in the Marshall Islands in the Pacific, which has forced the government there to issue a state of emergency warning; France observed its warmest winter since records began; while the sea ice that has formed in the Arctic this winter is about a million square kilometres less than its average for this time of year.

There sea ice was not reduced and surface temperatures average 5 to 10 ° cooler, and the steep winter warming trend was not observed.

Since the millenium, exceptionally strong storms have prevailed globally, oceans are covering once habitable islands, Beijing is suffocating, 100 year and 150 year floods are frequent, major aquifers have been depleted (the Salton Sea is drying up), weather patterns have changed drastically, winters in the S.E.states are definitely experiencing drastically warmer averages (some areas only 10 - 14 nights of freezing temp vs. 1970 28 - 30 nights of freezing temp).

The bright white central mass shows the perennial sea ice, which is just the multi-year ice that has survived at least one summer, while the larger light blue area shows the full extent of the winter sea ice including the average annual sea ice during the 2012 months of November, December and January.

«Antarctic sea ice shows no sign of summer retreat, and the current winter's peak extent is well above average.

The weather records that the team collated showed that sea surface waters have warmed by an average of 0.9 °C in the summer - and 2.3 °C at the height of the southern winter, in August - since 1925.

Every year, sea ice around it comes (in winter) and goes (in summer), and over time tends to average out.

Of the 15 million square kilometers (5.8 million square miles) of sea ice that exist during winter, on average, 7 million square kilometers (2.7 million square miles) remain at the end of the summer melt season.

During boreal winter (December 2016 to February 2017 - DJF) it was much warmer than average throughout the Arctic, whereas in spring (March to May 2017 - MAM) the relative warmth was less widespread, with a region near the Greenland Sea being particularly cold relative to the average.

The thermometers out there (even the ones next to AC exhausts in the summer or heated buildings in the winter) tell us that the «globally and annually averaged land and sea surface temperature» has not risen over more than a decade (in fact it has cooled slightly).

«The trend in sea ice decline, lack of winter recovery, early onset of spring melting, and warmer - than - average temperatures suggest a system that is trapped in a loop of positive feedbacks, in which responses to inputs into the system cause it to shift even further away from normal.
