Scientists in the Arctic are warning that this summer's record-breaking melt is part of an accelerating trend with profound implications.

Norwegian researchers report that the sea ice is becoming significantly thinner and more vulnerable.

Last month, the annual thaw of the region's floating ice reached the lowest level since satellite monitoring began, more than 30 years ago.

It is thought the scale of the decline may even affect Europe's weather.

......

During a visit to the port, one of the scientists involved, Dr Edmond Hansen, told me he was "amazed" at the size and speed of this year's melt.

"As a scientist, I know that this is unprecedented in at least as much as 1,500 years. It is truly amazing - it is a huge dramatic change in the system," Dr Hansen said.

Isn't that what normally happens when ice melts?

One of the most critical facts about the decline in summer sea ice from AGW warming is that the resulting increase in solar insolation is bound to amplify the effects of AGW strongly. It has been estimated that the loss of polar ice cover is equivalent to 20 years of global warming.
And it is located in the perfect spot to amplify melting of the Greenland Ice Sheet and the methane hydrates locked into Arctic 'permafrost', two other sources of potential amplification.

Several websites & large percentages of readers predicted large percentage Arctic sea ice losses due to ever thinning ice. Large percentages of readers polled for March 31, 2011 predicted 3 million square kilometers for 2011 Arctic sea ice minimum were not accurate for 2011, but look to be fairly accurate this year.

Well could all the hot air spewed by the dirtling be responsible for the change in climate?

The best photos of the Arctic sea ice retreat would be taken northeast of the Severnaya Zemlya Islands, far north of Siberia, from where the heat has poured to melt so much of the Arctic sea ice.

There is a 500(?) mile long, & 20 degree(?) wide region of clear ocean that penetrated hard into the Arctic sea ice pack, interrupted only by a 30 mile(?) wide, 30% sea ice concentration. Without the 30 mile wide 30% sea ice, continuous clear ocean would have extended within 300(?) miles of the North Pole itself.

Its all going away!

Truly, phenomenal!

Tho the Northwest Passage began icing up some days ago, a recent warm spell 60+ degF, in Northwestern Canada & Northeastern Alaska re-melted the Passage.

Other warm spots including extended warmth above 80 degN & also high latitude Finland & western Russia continue clear high latitude Arctic waters, tho the sun is low on the horizon at its very highest.

There is a 500(?) mile long, & 20 degree(?) wide region of clear ocean that penetrated hard into the Arctic sea ice pack, interrupted only by a 30 mile(?) wide, 30% sea ice concentration.

Surprisingly, the easily wind & current obliterated 500 mile long region of clear ocean, penetrating the Arctic sea ice pack, with an even frailer 30 mile wide, 30% sea ice concentration has continued for ~ a week! Next to it, sea ice concentration of higher ice content has reduced in both size & sea ice concentration. If the 30% sea ice concentration did melt, clear Arctic ocean would extend to within 300 miles of the North Pole, with absolutely no need of an ice breaker, or even ships of heavy bow construction..... some boat. However, it would be a sailing event of great risk, depending completely on the continued warm stable weather pattern, & gentle winds & current. It really would be a suicidal adventure.

But what if the right boat was at the right place & that 30% concentration did melt........ or maybe someone could maneuver around those ice chunks...... some Russian, Finn or high latitude adventurer might try it.

Latest about Arctic sea ice melt 'and recovery':

Barely ABOVE 4 million km2, Arctic sea ice extent is still BELOW any recorded level in any previous year for ~6 weeks, presently at 4,166,563 km2 (October 2, 2012), fractionally gaining ~25,000 km2(a bit more than West Virginia area) of sea ice the previous day, despite the sun, unseen, from the North Pole for 10+ days, & temperatures above the 80th parallel, a bit above -13 degC, fractionally above normal. Much warmth built up in Arctic waters these past months is resisting its conversion back to sea ice, especially southern Arctic waters which have seen much more solar energy absorbed than northern Arctic clear waters.

Only along the Greenland east coast is sea ice extending greatly south. All other regions, including the Northwest Passage, Northeast Passage & Arctic waters, south of the Arctic Ice Pack, resist conversion back to Arctic sea ice.

IN ADDITION, for months, any downwellings in the Arctic waters that have been ice-free, have been conducting much captured solar energy radiating on those clear waters, to the depths of the continental shelves & Arctic Ocean.

This same Arctic Ocean warmth is & will continue to keep Arctic sea ice thinner through the coming winter & even spring. As of October 2, Arctic sea ice VOLUME is ~23% lower than any satellite recorded year AND indications of submarine-detected Arctic sea ice VOLUME.

Yes, the Arctic sea ice Volume is disappearing, day to day, & year to year, quicker than the Arctic sea ice extent, even in the time of Arctic sea ice increase.

What's the worst possible scenario if all the Arctic ice melts?

How many billions of people will die as a result?

The worst result to toxic topix AGW denier "steenking piddling diddling middling mudling mudslinger dirtling", who is a slimy steenking filthy vile reprobate rooting(& rotting) racist pukey proud pig, is that more AGW scientists' predictions are & will come true.

Wait and find out.

But estimates you can get by the barrel. Science has been estimating the impact for a while now. Separating it from the other effects, such as the poleward movement of the 'desert bands' around the equator will take time. That is the problem with climate. There is never any single consequence. And you need to give a time span for the consequences. Some billions are likely to die from the loss of the Greenland Ice Sheet. Did they die from the speed up of the melting or do you count that it would have melted anyway. Do future deaths (discounted) from a slower sea level rise count less than the deaths from a more rapid sea level rise?

Maybe if you could ask a SENSIBLE and REASONED question, there would be a more reasoned answer.

There isn't enough time left for that to happen.

Of course there is, it's CO2, at least that's what we're asked to believe.

They're not dead yet.

Sea level rise won't 'kill' anyone.

Correction:
'wugmump' should be mugwump.
Both ways, sound funny, altho republicans aren't funny. However, re-pubic-lick-uns sound almost as funny as mugwumps.
