Smoke from Russian Fires Over Arctic Sea

From NASA: (satellite image follows) one wonders what this will do to the albedo of sea ice. Numerous wildfires have dotted the Russian landscape this past summer fire season.  Although not quite as the adage says, although still true, where … Continue reading ?

Snow has thinned on Arctic sea ice, study finds

Modern measurements and historic observations provide a decades-long record showing that the snowpack on Arctic sea ice is thinning. What thinner snow will mean for the ice is not certain. Deeper snow actually shields ice from cold air, so a thinner blanket may allow the ice to grow thicker during the winter. Show More Summary

Snow has thinned on Arctic sea ice

From the University of Washington From research stations drifting on ice floes to high-tech aircraft radar, scientists have been tracking the depth of snow that accumulates on Arctic sea ice for almost a century. Now that people are more concerned … Continue reading ?

WUWT Arctic September Average Sea Ice Prediction submitted to ARCUS

Here are the numbers from the poll started yesterday. 657 votes were cast on the question “What will the September monthly average Arctic sea ice extent be? “and the breakdown is shown below. The top 5 vote getters, garnering 55% … Continue reading ?

August Arctic Sea Ice Outlook Contest

The Sea Ice Prediction Network (SIPN) announces the call for contributions for the Sea Ice Outlook August report. The Sea Ice Outlook provides an open process for those interested in arctic sea ice to share ideas about the September minimum … Continue reading ?

Sea ice news Volume 5, # 5 NSIDC: ‘the expansion in Antarctic sea ice is confirmed’

From NSIDC: Sled dog days of summer NSIDC reports near record Antarctic sea ice extent in July Arctic sea ice extent declined at a fairly rapid rate through the first three weeks of July, but the loss rate then slowed … Continue reading ?

Unforced variations: Aug 2014

This month’s open thread. Keeping track of the Arctic sea ice minimum is interesting but there should be plenty of other climate science topics to discuss (if people can get past the hype about the Ebola outbreak or imaginary claims about anomalous thrusting). As with last month, pleas no discussion of mitigation strategies – it […]

Melt ponds shine in NASA laser altimeter images

Even from 65,000 feet above Earth, aquamarine melt ponds in the Arctic stand out against the white sea ice and ice sheets. These ponds form every summer, as snow that built up on the ice melts, creating crystal clear pools.

Once-Frozen Arctic Sea Now Gets 16-Foot Waves

Good news for Arctic surfers? The Beaufort Sea, part of the Arctic Ocean, was long covered in a perpetual layer of ice; not so anymore. Now, the area has seen waves 16 feet high thanks to warmer temperatures, scientists say in a new study, per National Geographic. The giant waves...

Satellites Capture Wildfire Smoke Reaching Fragile Arctic Ice

It's the height of the Arctic melt season — do you know where your ice is? While Greenland and the Arctic sea ice cover have shown no signs of shattering melt records once again this year, satellite images taken on Friday and duringShow More Summary

In the Arctic Ocean, researchers find big waves where there once was ice

For the first time, researchers were able to measure waves in the Arctic's Beaufort Sea due to melting ice caused by global warming. "Waves could accelerate the ice retreat," Jim Thomson of the University of Washington told The Washington Post. Show More Summary

You, Too, Can Sleep on Sea Ice and Track Polar Bears

Trade beaches for icebergs on a summer excursion to the tiny hamlet of Pond Inlet in the Canadian Arctic.

Huge Waves Measured for First Time in Arctic Ocean

As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water which is predicted to extend

Huge waves measured for first time in Arctic Ocean

As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water which is predicted to extend across the whole Arctic Ocean before the middle of this century. Storms thus have the potential to create Arctic swell – huge waves that could add a new and unpredictable element to the region. read more

Study: An Arctic Oil Well Blowout Could Spread More Than 1,000km

Oil from a spill or oil well blowout in the Arctic waters of Canada's Beaufort Sea could easily become trapped in sea ice and potentially spread more than 1,000 kilometres to the west coast of Alaska,

The Expansion of Antarctic Sea Ice and Self Correcting Science

One of the things climate change science deniers say, to throw you off, is that Antarctic sea ice is expanding. They even claim that the amount of expansion of Antarctic sea ice offsets the dramatic retreat of Arctic sea ice (see this for the latest on the Arctic). I’ve even seen it argued, in that…

Current Status of Arctic Sea Ice Extent

As it does every summer, the Arctic Sea ice is melting off. Over the last several years, the amount of sea ice that melts by the time it hits minimum in September has generally been increasing. So, how’s it doing now? The graph above shows the 1981-2010 average plus or minus two standard deviations. Before…

Hi-Tech Quest for Arctic Sea Ice Answers

last monthNews : Truthdig

By Tim Radford, Climate News Network A sophisticated array of automatic sensors will allow scientists to conduct the longest ever monitoring programme to determine the precise physics of summer sea ice melt in the Arctic.
