.. My tip 4.7 mill. km ²
Hi Neven ! An exciting story. We see how it will begin. And we will see how it will end. But I am also the melting season in 2013, Memory. Since the water was cool, after the water has frozen in late October 2012. It was cooled by high waves well, and was colder in the summer of 2013. This year we again experience the summer with warm, insulated water. The Laptev will be very fast without ice.

Neven I think there were at least 15 km ². Including their own speed.
Hi Neven ! I think the melt will be stronger this year than last year. The water temperature will be slightly higher than 2013. The fast freeze in October (Laptev and ESS), the water quickly isolated and could not cool down. The Baffin Bay is ice-free faster and MYI in the Boufort is already rotten and has the water including isolated. I am still of the opinion that there is a 2-year Cyklus. In October 2012 the water was quite chilled, what the Melt has slowed in 2013.

Hi all ! At the moment we have thick ice where in summer it is very likely to disappear (Kara, Hudson, Boufort). But in the Arctic basin, it is as thin as ever.
Werther , Neil Thank you very much

Hi Neven ! Slightly Off Topic As we see in Modis actually not much of the Arctic, the Antarctic often I look at the moment. There is a glacier, whose tongue 40 - 50 km extends in the open sea. I find that strange. The glacier is located approximately in the center of the image. http://lance-modis.eosdis.nasa.gov/imagery/subsets/?subset=Antarctica_r02c04.2013318.terra.250m Since the tongue is stable for years, I think he's sitting on ground firmly. But what surprises me. But he must have made ​​a deep ditch. Maybe Espen Olsen and Mauri Pelto know more about these glaciers in the Ross Sea. Have a nice day, and enjoy using your new house. Gerhard

.. If you look at the ice-minimum seen from 1991 - 1997, you can see a very clear 2-year rhythm.

.. A little forethought for the Arctic. After some more ice is left , we are currently seeing a faster freezing of the East Siberian Sea and the Kara Sea . This does not automatically mean that we have to expect there next year thicker ice because rapid freezing may also have the effect that the underlying water is previously isolated before it can cool down the cold winds up at greater depths . As we saw in the previous year despite late freezing surprisingly thick ice in the Kara Sea . Similarly, it was also in the Hudson Bay . I am of the opinion it could mean a negative feedback effect this isolation . This would mean a 2 year cycle with the minimum cover , which also seems quite logical to me . The Bouforth Lake got by the strong winds in the summer much MYI ( multi-year ice ) was inserted , which is still the direction Tschukschensee drifts . I expect from mid- November, a rapid decrease in the drift velocity . Worries me the thin ice of Greenland north of Morris Yessup to Fram Str . . It is currently only half as thick as in October 2012. What will mean that there will not be far to the south in the coming melt season . Also the Jöklbucht is already occupied with fresh thin ice , so no MYI can drift to the coast to spend the winter there . This will have a rapid warming of Greenland's east coast next summer to follow . Be particularly felt that the East Greenland glacier as Zachariah , 79, and Storstossen Bistrup . Above all, the melt of the basal Kalbungsfronten will not miss its effect . Whether there is a large increase in the flow rate when Zachariah remains to be seen . He is in my opinion a sleeping giant . Now to the Barents Sea . The ice cover there is a distinct question of wind patterns and can lead to very large differences in coverage. Currently, we have very strong winds from the Arctic basin towards the Barents Sea will continue for one week. That is why on the atlantic side of the Arctic ice are more advanced than the previous year , although this year it is melted over there , 2012. The Bering Sea , I expect this year not as fast as ice-covered last year , because the temperatures are relatively warm layers of water up to 30m deep and are therefore not adapt with certain inertia changing winds. In the next summer, it will be interesting to see how quickly the Bering Sea is ice-free and the Tschukschensee opens. But anyway , I think that is the Achilles heel of the Arctic Barents Sea .

So, I 'm back from Greece . Was nice to sail in the Aegean sea . but many Jellyfish. The water was too warm. Well, I do not think the ice has recovered in the Arctic this year . The most worries me the thin ice north of Greenland. for east Coast of Greenland that is something very bad . The ice from the Arctic in the summer of 2014 not drift far to the south. It will hardly come through Fram Strait . MYI is gone on the east coast . Now there are 30 - 50 cm of ice , where in 2012 at this time 2 - were 3 m ice. In the summer of 2014, which quickly disappear . The water is warmer. What this means for the glacier? Zachariah , 79, Bistrup and Storstossen will experience a strong basal melt. I do not know if it will increase its flow rate quickly . But they will . The open water at the calvingfront of Zachariah is to awaken from his sleep . And he is a giant. He may soon overtake the Jacobshavn glacier .

Oh Sorry ! "But otherwise were the average temperatures in the Antarctic June to September too high."

NJSnowFan The Antarctic is the climate in the NH barely influence. The large ice in the Antarctic has also another reason. It is very broken. The floes are drifting far to the outside. In Rothera we had +4 ° C in September. Neumeier is accustomed to something cold. But otherwise were the average temperatures in the Antarctic One must also note the thermohaline circulation. The surface currents (NA-current) transport the water in a relatively short time from the south to the north. But! The depthwater needs from north to south + / - 1000 years. This allows the ocean to save a lot of heat. And for 1000 years. June to September too high.

It now come the days where the sun can appear directly underneath the clouds. The long-wave Radiation will keep the ice and the water warm. It is more convective clouds produce. It is the final of the melting season. Another aspect is the widely scattered ice. If the new ice is lower, the wind has a good attack. The drift is stronger in the next year. The new ice is broken at every slight storm. The columns must be new ice forming. From year to year more ice must re-form in the winter. Were there earlier in the September in the Arctic Basin (about 7.5 mil sq km) for about 6mil sq km ice, so there are in recent years, only 2.5 to 3 mils sq. km. This means it must be there now every year Produce three times as much ice new, than before. That is, it drops 3 times as much water in depth, what needs to be replaced again. The termohaline circulation is stronger. And the Barents Sea warmer. http://www.seas.harvard.edu/climate/eli/research/equable/ccf.html

... Maybe it's just coincidence. But why HYCOM has changed its data when the NO-passage is open? Maybe they are committed to providing low to no data for navigation. This could have serious consequences. But maybe they got better and more accurate data from the ships.

... It was a very interesting year 2013. There were many factors that have helped to keep the ice. But the fact remains that warms the Barents Sea from year to year. I am of the opinion it will take a long time until the Arctic is ice-free. But they will one day free of ice. A rise of sea water of 1m, would bring a very different flow behavior of Pazific through the Aleutian Islands with it. It would flow much more warm water into the Arctic.

.... Serezze may be right. The storms have kept the ice. But still, there is a crucial point. The SST. I dare say that if the SST would have been only 1 ° C warmer on average, everything would have looked quite different. In the dissertation I read somewhere that the storms are periodic. There was: every 7 years is a storm season.
... A steel cable with 100 km can be very elastic. It throws back the ice. I think 150 mm diameter should be enough. Maybe even twice. Buoys as you can Take mesh box container. The waste industry and are stored as waste in different Companies and farmers. They are UV-resistant

... Some ideas are pretty crazy. http://en.wikipedia.org/wiki/Climate_engineering
... To change something, you need different people. 1) People with feeling, see what happens. 2) People with mental abilities that calculate can, where we are heading. 3) People like Neven, the people who say that something must be done. 4) People with ideas that say what you can do. 5) People with money who fund these ideas. I myself am not a scientist. I am a carpenter. I think practically. If you want to regulate something, you should 5000 buoys and a long steel cable arrange, shut off and the Fram Strait. That would not be as expensive as other absurd ideas. I think if you hold the ice back to the Fram Strait, the Arctic will recover.
