The National Snow and Ice Data Center reports that Arctic ice shrank by 131,000 square miles between August 17 and 21, leaving ice coverage that is well below the 2005 record low of 2.05 million square milIce Data Center reports that Arctic ice shrank by 131,000 square miles between August 17 and 21, leaving ice coverage that is well below the 2005 record low of 2.05 million square milice shrank by 131,000 square miles between August 17 and 21, leaving ice coverage that is well below the 2005 record low of 2.05 million square milice coverage that is well below the 2005 record low of 2.05 million square miles.

His 2011 data show the lowest coverage of sea ice since records began.

Last summer that coverage shrank to 1.67 million square miles, the second - lowest number on record, according to climatologist Mark Serreze of the National Snow and Ice Data Center in Boulder, Colorado.

At the moment, this year's annual summer minimum Arctic - wide ice coverage is the fourth lowest on record, with similar low coverage in the NWP, according to information provided by the Canadian Ice Serviice coverage is the fourth lowest on record, with similar low coverage in the NWP, according to information provided by the Canadian Ice ServiIce Service.

Arctic sea ice coverage is still below average and the previously stable Antarctic sea ice extent was at or near a record low, the statement adds.

Qualitative indicators like sea ice coverage, spring thaw dates, and melting permafrost provide strong additional evidence that trends have been positive at middle and high northern latitudes, while glacier retreat suggests warming aloft at lower latitudes.

During the so - called Holocene Climate Optimum, from approximately 8000 to 5000 years ago, when the temperatures were somewhat warmer than today, there was significantly less sea ice in the Arctic Ocean, probably less than 50 % of the summer 2007 coverage, which is absolutely lowest on record.

It also appears that the sea ice volume continues its steady decrease, and has set a new record low — that story is getting some coverage:

Given that this summer's minimum has fallen below last year's and will settle in at the 2nd or 3rd lowest on record, last summer's minimum now appears more as a bump in the road toward continuing lower Arctic sea ice coverage.

It is not that the polar regions are amplifying the warming «going on» at lower latitudes, it is that any warming going on AT THE POLES is amplified through inherent positive feedback processes AT THE POLES, and specifically this is primarily the ice - albedo positive feedback process whereby more open water leads to more warming leads to more open water, etc. *** «Climate model simulations have shown that ice albedo feedbacks associated with variations in snow and sea - ice coverage are a key factor in positive feedback mechanisms which amplify climate change at high northern latitudes...»

In the Great Lakes, the average annual maximum ice coverage during 2003 - 2013 was less than 43 % compared to the 1962 - 2013 average of 52 %, 99 lower than any other decade during the period of measurements (Figure 18.7), although there is substantial variability from year to year.

For Antarctica, the lowest maximum extent, recorded on September 12, follows a record low minimum sea ice coverage recorded on March 1 after the summer thaw, he said.

This came as a shock to researchers who saw Arctic sea ice coverage shrink to a documented low in 2012.

«The last couple of years has been so low with ice coverage that this year looks good in comparison to that, but doesn't look so good in comparison to the multi-decade average.»

Sea levels are a foot higher and Arctic ice coverage is at the lowest levels ever — the ice was gone as of March, months early.

However, now sea ice coverage has expanded to reach the sixth record low, according to AFP.

As a consequence, any sea ice coverage ensemble forecast that uses the 2007 temperature and specific humidity fields as part of the input surface BCs will approximately have the 2007 sea ice minimum as the lower end estimate of the ensemble.

As to the Arctic icecap, the Daily Mail conveniently fails to mention that the 60 % increase in 2013 over 2012 still leaves the icecap coverage 20 % lower than it was in 1978, when NSIDC's record - keeping on the extent of Arctic ice began.

This coincided with record - breaking shrinkage of Arctic sea ice, where total coverage at the peak of melting season is now 40 percent lower than in the late 1970s.

Based on results of a simple model that keeps track of the age of ice as it moves about on the Arctic Ocean, we argue that the areal coverage of thick multi-year ice decreased precipitously during 1989 - 1990 when the Arctic Oscillation was in an extreme «high index» state, and has remained low since that time.

Sea ice coverage is particularly low in the Barents and Kara seas, which sit north of Scandinavia and Russia and have been in the path of those incoming storms.

Albedo should increase in response to very low solar conditions which should result in an increase in major volcanic activity, increase in global cloud coverage and sea ice / snow coverage.

We know from ship's logs that ice coverage was low in the 1940s and from history we know that Amundsen sailed the NW passage in 1903 and reported little ice cover.

This year, ice coverage has reached record lows for the early northern winter.

«When IP25 [proxy for sea ice] is absent, lack or very low abundance of phytoplankton biomarkers reflects permanent sea - ice coverage, whereas elevated abundance of phytoplankton markers reflects ice - free conditions.

The Statement also highlighted that long - term indicators of climate change such as increasing carbon dioxide concentrations, sea level rise and ocean acidification continue «unabated», with Arctic sea ice coverage remaining below average and the previously stable Antarctic sea ice extent at or near a record low.

Scientific confidence of the occurrence of climate change include, for example, that over at least the last 50 years there have been increases in the atmospheric concentration of CO2; increased nitrogen and soot (black carbon) deposition; changes in the surface heat and moisture fluxes over land; increases in lower tropospheric and upper ocean temperatures and ocean heat content; the elevation of sea level; and a large decrease in summer Arctic sea ice coverage and a modest increase in Antarctic sea ice coverage.
