Skip to comments.Arctic ice cap to disappear in 20-30 years: study

LONDON (AFP) The Arctic ice cap will disappear completely in summer months within 20 to 30 years, a polar research team said as they presented findings from an expedition led by adventurer Pen Hadow.
It is likely to be largely ice-free during the warmer months within a decade, the experts added.
Veteran polar explorer Hadow and two other Britons went out on the Arctic ice cap for 73 days during the northern spring, taking more than 6,000 measurements and observations of the sea ice.
The raw data they collected from March to May has been analysed, producing some stark predictions about the state of the ice cap.
"The summer ice cover will completely vanish in 20 to 30 years but in less than that it will have considerably retreated," said Professor Peter Wadhams, head of the polar ocean physics group at Britain's prestigious Cambridge University.
"In about 10 years, the Arctic ice will be considered as open sea."
Starting off from northern Canada, Hadow, Martin Hartley and Ann Daniels skied over the ice cap to measure the thickness of the remaining ice, assessing its density and the depth of overlying snow, as well as taking weather and sea temperature readings.
Across their 450-kilometre (290 mile) route, the average thickness of the ice floes was 1.8 metres (six feet), while it was 4.8 metres when incorporating the compressed ridges of ice.
"An average thickness of 1.8 metres is typical of first year ice, which is more vulnerable in the summer. And the multi-year ice is shrinking back more rapidly," said Wadhams.
"It's a concrete example of global change in action.

It’s going to snow tonight in parts of eastern PA.

‘shovel ready’ are ye? ;-)
B, as in B.
S, as in S.
It looks like the great Northwest passage has finally been discovered. If only the great explorers were alive today, they would be hailed as prophets of global warming and enshrined in the leftist hall of fame.
20 or 30 years ago Florida was going to be under the same artic snowcaps.
An old story, that is disproved by this rapid freezing of the arctic ice cap this summer, earlier than in past years.
It’s always 30 years away. Just long enough to be unprovable.
Moving in on the Twin Cities tonight.
This will be our third measurable snowfall so far this month. Never before in recorded history.
I wonder if I could bet against this in Las Vegas?
Has the alleged ice melting been tracked with overall global temperature changes? Can a spell of warming that ended a decade ago take a while to show up in the Arctic ice, like an echo? Might the polar bears in the meantime find themselves comfortable on more southerly land areas that freeze well? (They are basically white versions of brown bears.) Being able to freely navigate the Arctic for a while might have its advantages for people in the meantime.
The ice is thicker than normal this summer.
these people know their scam is about up.
Hurry, because Las Vegas may be covered in ice by then!
Weren’t these people touting the coming “Ice Age” 30 years ago? Hmmm... must have lost their funding..... Had to start a new cult....
More open seas to hunt whale!
The Arctic ice cap has been growing since the low of 2007:
And the Antarctica hit a new high this year.
You noticed that too? Close enough to give a “chill” and too far to make it irrelevant. They can’t even offer a weather forecast beyond the afternoon. We’re all doooooooomed. Submit Submit!!!!!!1
Liars hiding behind scientific degrees.
20-30 years away, just like flying cars have been for the last 60 years.
Went to the pole. Froze my ass off. Looks the same. Can't report that, lose funding. Make prediction for year 2039. Note to myself, next expedition to Hawaii to find out why macadamia nuts cost so much

if they only stayed 5 more months....
There was 5” of snow at my house on October 1st with two more measurable snowfalls since then. This is at 43* N latitude. The Polar ice cap starts at about 70* N latitude above Alaska, further south in some areas.
These guys are full of shiite.
Just send me your checking account number and transmittal information.....

Great! Maybe we can grow tomatoes up there seeing as how the government has destroyed our tomato crop here in the Central Valley. I claim this new land for Central California!
When I saw this it jogged a memory from back in the spring when they pulled this stunt. It seems the poor researchers got stranded in the arctic due to horrible weather (cold, wind, snow) and had to be rescued.
“They were down to half-rations and battling desperate sub-zero weather conditions.”
“During the past 18 days, temperatures dropped below minus 40 degrees Celsius”
“Three earlier flight to drop food supplies to the team had to turn back because of bad weather.”
“We’re hungry, the cold is relentless, our sleeping bags are full of ice”
Nice alarmist title they used; the first sentence of the article contradicts it.
BULL SHI!!!!!!!!!!!! Liars!
The Watt’s UP With That website (www.whatsupwiththat.com) tracked this hapless collection of so-called polar explorers on their mission to the north pole. They were utterly inept and produced no scientifically useful data whatever. They came no where near their stated goal of the north pole and had to be rescued.
I recommend those interested to go to the site and read about the foibles and self-inflicted travails of these idiots.
It’s laughable that from this worthless expedition that produced worthless data they can now forecast polar conditions 30 years from now.
The real problem is the media, that acts as the enablers for these frauds and dispenses their lunatic fantasies to an uncritical public.
BUMP for later read
Globull warming may cause ice to melt at lower temperatures (sarc):
“Ocean Heat Content: Dropping again”
Scientists say that Earth will be so hot it is uninhabitable in less than 2 days!
Dr. Stan Fulzenblatz of the National Environmental and Fearmongering Organization reports today, "I measured the temperature this morning at 43 degrees Fahrenheit. By 1 PM this afternoon, the temperature was 68 degrees! If this rate of warming continues, the temperature will be over 168 degrees by the day after tomorrow, effectively destroying all life on the planet. We're doomed!" Scientists say that, unless we all reduce our standard of living to prehistoric levels and immediately swear allegiance to Obama, civilization as we know it will be obliterated...
Go to Hawaii to research increased greenhouse gas emissions noted by NOAA monitoring station as primary support for “global warming” theory.
Do not reveal that monitoring station is within 10 miles of an active volcano that has been erupting continuoulsly since the 1980s. Do not mention that eruptive activity has increased substantially for past several years. Do not mention that observation results may well have been corrupted by volcanic gases.
I won’t live long enough to disprove these fools.
Actually these morons had to abandon their mission and get rescued almost 500 kilometers from the pole. Their high tech ‘radar’ sled broke down in the frigid conditions so they had to resort to drilling old fashioned holes to measure ice thickness. By ANY measure their mission was a FAILURE and the ‘science’ they claim to have gathered is worthless.
Here we go again!
How’d you hold up in the storm? We did okay here.
Good! That would clear the way for many more beach front properties!
A dirty little secret of the warm-mongers is that Arctic measurements begin with a baseline of 1979, which happens to coincide with the start of a short-term warm period that ended around 2000, as governed by a rather normal Pacific Decadal Oscillation, which has now changed phases. At the same time, sunspots have been almost non-existent for more than a year, pointing to reduced solar output and at least the potential for a so-called "solar minimum", past occurrences of which have coincided with little "Ice Ages".
In any event, I am convinced that activities of human beings have nothing to do with it, and any assertion to the contrary has no valid scientific support of which I have become aware. If you are tempted to believe the CO2 hypothesis, just look at the trend lines during the past ten years or so: CO2 concentrations rise as global temperatures drop. That would be a negative correlation. There are, in fact, far more mechanisms at work here than can be described in a small space. Instead: follow the money.
