Skip to comments.Rapid Melting of Arctic Sea Ice Possibly Explained [new theory?]
Posted on 07/01/2011 6:46:52 PM PDT by smokingfrog
Arctic researchers have discovered a clue as to why sea ice in the North is melting so much faster than anyone thought it would.
Scientists have long puzzled over why Arctic sea ice is retreating at up to three times the rate that climate models say it should.
In an effort to answer that question, a group of U.K-based explorers walked more than 500 kilometres of sea ice in the High Arctic, taking temperature readings of the ocean below them.
They found a layer of cold, salty water about 200 metres down that they suspect has come from the melting of first-year ice.
That meltwater has forced the relatively warmer water to the surface, where it's speeding up the decay of more ice. 'Complicated processes'
"We're trying to understand why the ice is melting so fast," said Simon Boxall of the Catlin Arctic Survey. "It's not just down to simple warming. There are more complicated processes."
The speed at which sea ice is disappearing in the Arctic has far exceeded almost all predictions and alarmed climate scientists.
A 2007 paper from the National Snow and Ice Data Center in Boulder, Colo., found that the projections of the UN-sponsored Intergovernmental Panel on Climate Change were already obsolete three years after they were published.
When projections from the panel were compared with actual observations, the authors found that between 1953 and 2006 the sea ice was retreating three times faster than it should have. Between 1979 and 2006, when satellite data was available, the actual retreat was twice as fast as climate models predicted.
The report concluded that sea ice retreat is 30 years ahead of where scientists thought it would be.

Guess we won’t be seeing a Arctic Sea Ice Road Trucker show anytime soon.
That's it for Simon...no more research grants on the causes of AGW. He's toast.
Now that science is political, we’ll never know...for sure.
I take it we’re all still going to die?
Just need to buy some seaside property on the arctic ocean and I’m all set :)
This is going to do wonders for world trade when the ice is significantly gone.
You know what? I don’t care how fast sea ice melts. I just want US oil companies to start drilling on the north slope so maybe I can afford a gallon or two of gas now and then. Oh yeah, make it 100% petroleum gas, no ethanol please.
Wait......Are we doomed?
I am not very sure that the arctic ice really is melting away as they tell us. The reason why, is that the north-west passage is still iced up. We were told that it would open all year around, because of global warming, but in recent years, it has only had a few weeks open in summer. And some years, frozen solid all through the year.
One well known factoid about predictions is that by this time (2011) Greenland should have been pretty much cleared of ice.
Obviously that's not what has happened. It's still covered with ice.

The ice in the drink in front of me is all gone, I had expected it to last much longer. So, I guess I'll have to agree with these climate scientwits, and be alarmed too.
Could be undersea volcanoes.
Anyone ever notice that the more skeptical people become about anthropogenic global warming/climate change, the more alarmist the articles describing the effects of AGW/CC become?
The ground under Yellowstone is lifting, and I don’t think anyone knows what that means. Volcanoes erupt, the earth quakes, the magnetic poles move and sometimes switch, and we still don’t understand exactly how. That we don’t understand the geologic influences on the melting of arctic ice is not surprising.
The latest prototype weather control machine from Rovenschmirtz Evil Inc?
Which isn't happening anyway, so that excuse is real weak.
BINGO! The first use of the Northwest Passage since the 1800's! Imagine the trade 'across the top of the world' instead of around it at a lower latitude! Crude oil from Barrow to New York, over the top!
Did your drink run all over when the glass overflowed? (8^D)
Clowns! Need to join a circus.....
Do you know how the beaches are up there? You should be able to get a nice tan with the sun up so long in the summer. I might open a little jet-ski rental shop since this looks to be the next summer "hot spot" for the jet set.
Causes these climatologists are ignoring:
* We’ve had an uptick in earth quakes and volcanic activity in recent years - Iceland being one of them. Could undersea volcanic activity like hidden lava flows and venting be causing this ice to melt?
* Industrial waste heat is on the rise along with industrialization. Norway, Sweden, Russia’s Far East all still have industrialization and far more waste heat. The heat bubble effect could be exaggerated and melting the ice near the coast, without specifically being “global warming”, just warmed air near the ocean surface OR warmed water from their rivers making it to the ocean.
Blame the Amish, Tea Partiers, Bush, Gun Toting Bible Hugging Christians but for God’s sake don’t blame Mother Nature (Gaia).
Wouldn’t be surprised to have a volcano forming underneath. That would explain a lot of it if true.
The only way to solve this problem is to immediately raise taxes on the 47% of people in the US that still pay taxes, and allow Gore, Obama and their friends to make billions trading carbon credits.
Scientists have long puzzled over why Arctic sea ice is retreating at up to three times the rate that climate models say it should.Why? The climate models have been wrong about literally everything.

Alas, not rapidly enough.
In the space of one hundred and seventy-six years the Lower Mississippi has shortened itself two hundred and forty-two miles. That is an average of a trifle over one mile and a third per year. Therefore, any calm person, who is not blind or idiotic, can see that in the Old Oolitic Silurian Period,' just a million years ago next November, the Lower Mississippi River was upwards of one million three hundred thousand miles long, and stuck out over the Gulf of Mexico like a fishing-rod. And by the same token any person can see that seven hundred and forty-two years from now the Lower Mississippi will be only a mile and three-quarters long, and Cairo and New Orleans will have joined their streets together, and be plodding comfortably along under a single mayor and a mutual board of aldermen. There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact."
Some people just have a way with words, don't they?
So basically, it’s the same effect as putting salt on the ice on my driveway... I know it’s more complicated than that, but that’s the start of the process.
The question is; what started this process in the first place? It can’t be global warming. The antarctic is gaining ice and snow.
I suspect those villianous reptiles from “V.”
Yeah but women and minorities will be hardest hit.
Is the white part the ice? It is nearly exactly the same.
Houston, we have a problem. And the problem is lying propagandists who want our money.
You nailed it. That was known about ten years ago. Marine volcanoes on the Arctic Sea floor.
>> The speed at which sea ice is disappearing in the Arctic has far exceeded almost all predictions and alarmed climate scientists.
Thus, the alarmists are indisputably wrong.
Ice Sheets from the last ice age still retreating?
Nah, couldn’t be that....
What’s this stuff about Monckton about?
Some of your links are stupid.
Posting both sides, where I find them.
Here's an example of another failed approach.
Here’s a link showing NASA changing the past data by 15% to show greater sea level rise:
