According to climate models, anthropogenic CO2 emissions drive trends in
polar sea ice.
If there is more than this warmer, if the
arctic polar sea ice completely melts within 5 years.
By the mid-2020s, sea level rise around Manhattan and Long Island could be up to 10 inches, assuming the rapid melting
of polar sea ice continues.
So the
north polar sea ice has been steadily thinning in depth and shrinking in area for more than 30 years.
A few days ago German website wobleibtdieglobaleerderwärmung (where's the global warming — hereinafter WBDGE) also looked
at polar sea ice.
Satellite images reveal clue to the hidden cause of fractures in Antarctic shelf ice that are calving huge icebergs into the
south polar seas.
While the global average rise is predicted to be between 30 and 106 centimetres, he says tropical seas will rise 10 or 20 per cent more,
while polar seas will see a below - average rise.
Total polar sea ice covered 6.26 million square miles (16.21 million square kilometers), which is 790,000 square miles (2 million square kilometers) less than the average global minimum extent for 1981 - 2010 — the equivalent of having lost a chunk of sea ice larger than Mexico.
This is a place where derelict former early warning / first strike runways, aircraft hangers and control towers were hastily converted into worker housing for the
new polar sea route activity.
Detail: This is a place where derelict former early warning / first strike runways, aircraft hangers and control towers were hastily converted into worker housing for the new
polar sea route activity.
The cooling
increases polar sea level pressure pushing the storms circling the pole into higher latitudes.
That these «events» should have a corresponding counter event is what concerns me
wrt polar sea ice melt.
Have any studies appeared on coupling of AMOC variation and that of
polar sea albedo from E. hux, Nitzschia and other plankton blooms?
Kara Strait - ice extent jitters Note that this sea ice will appear in extent numbers but will have no impact whatsoever on the mass of ice in the
main polar sea - ice cap.
Climate change may cause changes in migratory patterns, destroy habitat (particularly in nutrient -
rich polar seas), and drastically change ocean circulation, vertical mixing and overall climate patterns.
Southern polar sea ice reached its peak at the end of August, and November, December, January and February all saw rapid declines.
Released as officials from 190 countries meet in Durban, South Africa for the 17th UN Summit on Climate Change to discuss the future of international efforts on climate change, the study is just the latest to argue a growing urgency for slashing emissions in the face of rising extreme weather incidents and
vanishing polar sea ice, among other impacts.
Meanwhile, they said in interviews and in the summary, evidence of increasing warming has shown up in retreating glaciers,
thinning polar sea ice, retreating snow packs, warmer nights, and elsewhere.
So far, the ocean surface in warmer areas around the world has matched the increase in atmospheric CO2, but its unclear
whether polar seas are doing the same since ice covers the surface in the winter, shielding it from the atmosphere for months at a time.
The latter, which isolated Antarctica within a
cold polar sea, produced global effects on atmospheric and oceanic circulation.
Even the U.S. Department of the Interior has now proposed that polar bears be listed as threatened under the Endangered Species Act
because polar sea ice is melting — an extraordinary admission for an administration philosophically aligned with the skeptics.
Variations
in polar sea ice on short time scales, up or down, are essentially meaningless, my contacts studying the cryosphere always stress.
This near - infrared, colour mosaic from NASA's Cassini spacecraft shows the sun glinting off of Titan's
north polar seas.
21 December, 2016 — Satellite images reveal clue to the hidden cause of fractures in Antarctic shelf ice that are calving huge icebergs into the
south polar seas.
In the mid 1800s, some scientists and explorers — having not yet found a way through the forbidding sea ice sheathing much of the Arctic Ocean — posited that there was an «
open polar sea» beyond those barricades, nourished by warm waters sweeping north past Scandinavian coasts.
Naturally many factors
influence polar sea ice extent, such as weather patterns, winds, -LSB-...]
Although a recent downward trend in coverage is clearly visible by naked eye inspection, Goddard invites us to believe there has ``... been no net gain or loss
of polar sea ice since records began.»
Current scientific studies project that over the next few decades climate change will lead to an increase in
polar sea ice melt, rising sea levels, and natural disasters.
