That's the equivalent of a missing area of sea ice almost four times the size of Colorado, and puts this year right in line with a trend of ever decreasing
sea ice in the region as the climate warms.

Added to this the
seas in these
regions recede
as the gravitational pull of the
ice is no longer present, leading to the redistribution of this water to the equator.
So, the positive feedback between melt and velocities implies that more melt leads to higher velocities, which bring
in more
ice from cold
regions to warm
regions which increases the melt and hence the velocity etc, with
as a final result a rapid loss of
ice and hence an enhanced increased
sea level.

For example, reductions
in seasonal sea ice cover and higher surface temperatures may open up new habitat in polar regions for some important fish species, such as cod, herring, and pollock.128 However, continued presence of cold bottom - water temperatures on the Alaskan continental shelf could limit northward migration into the northern Bering Sea and Chukchi Sea off northwestern Alaska.129, 130 In addition, warming may cause reductions in the abundance of some species, such as pollock, in their current ranges in the Bering Sea131and reduce the health of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency of early Chinook salmon migrations, making management of the fishery by multiple user groups more challenging.1

Their theory seems to be not too inconsistent with rebuilding Arctic
sea ice in one
region as the heat transport done front advances South.
Ice mass balance buoys deployed
in the Beaufort
Sea as part of the Office of Naval Research (ONR) Marginal
Ice Zone Program indicate that surface temperatures have reached the melting point, at least intermittently,
in the
region, with some surface melt beginning
in the southern part of the Beaufort, but little or no melt farther north (Figure 10), http://www.apl.washington.edu/project/project.php?id=miz.
Behavior of the
sea ice over the past winter and the spring and the large positive temperature anomalies
in the Arctic (
as high
as 20 degrees C over large
regions in the past winter) suggest that an extent near that of the 2012 minimum may occur again if there is large export of
sea ice out to the Atlantic Ocean via the Fram Strait.
Any field - or ship - based updates on
ice conditions
in the different
regions such
as sea ice morphology (e.g., concentration,
ice type, floe size, thickness, snow cover, melt pond characteristics, topography), meteorology (surface measurements) and oceanography (e.g., temperature, salinity, upper ocean temperature).
Climate change signals are amplified
in polar
regions and indicators, such
as the collapse of
ice shelves and melting of
sea ice, have raised public awareness of the consequences of a warming world.
On November 30th, diplomats from the Department of State concluded 10 years of negotiations by finalizing a multilateral agreement to protect the central Arctic Ocean from overfishing,
as sea ice in the
region dwindles.
As the Arctic
sea ice melts, the water vapor delivered into the the atmosphere increases
in the polar
region, and so does the snowfall, so that the whole thing starts over again.
Global warming is causing land - based
ice to melt
in parts of Antarctica such
as the Weddell
Sea region.
Rapid
sea - level rise from these processes is limited to those
regions where the bed of the
ice sheet is well below
sea level and thus capable of feeding
ice shelves or directly calving icebergs rapidly, but this still represents notable potential contributions to
sea - level rise, including the deep fjords
in Greenland (roughly 0.5 m; Bindschadler et al., 2013), parts of the East Antarctic
ice sheet (perhaps
as much
as 20 m; Fretwell et al., 2013), and especially parts of the West Antarctic
ice sheet (just over 3 m; Bamber et al., 2009).
Over four years, it is reasonable to expect at least some warming (or cooling) below 900 m
as well
as in regions that Argo does not sample such
as under the
sea ice.

From a report described on the IPY (International Polar Year) site dated 2/25/09: «Snow and
ice are declining
in both polar
regions, affecting human livelihoods
as well
as local plant and animal life
in the Arctic,
as well
as global ocean and atmospheric circulation and
sea level.»
These data are also useful
in the study of unusual weather phenomena such
as El Niño, the long - term effects of deforestation on our rain forests, and changes
in the
sea -
ice masses around the polar
regions.
This allows us to use SST anomalies
as proxies for SAT anomalies
in regions without
sea ice.
In contrast to the polar
regions, the network of lower latitude small glaciers and
ice caps, although making up only about four percent of the total land
ice area or about 760,000 square kilometers, may have provided
as much
as 60 percent of the total glacier contribution to
sea level change since 1990s (Meier et al. 2007).
And
sea ice dwindled to record low levels
in both the Arctic and Antarctic, with the north polar
region warming twice
as fast
as the global average.
