Experts warn North Pole will be 'ice free' by 2040
Times Online ^ | December 11, 2006 | Lewis Smith

Ice is melting so fast in the Arctic that the North Pole will be in the open sea in 30 years, according to a team of leading climatologists.

Ships will be able to sail over the top of the world and tourists will be able visit what was, until climate change, one of planet’s most inaccessible landscapes.

Researchers assessing the impact of carbon emissions on the world’s climate have calculated that late summer in the Arctic will be ice-free by 2040 or earlier - well within a lifetime.

Some ice would still be found on coastlines, notably Greenland and Ellesmere Island, but the rest of the Arctic Ocean, including the pole, would be open water.

The Nasa-funded US team of researchers said the ice retreat is likely to remain fairly constant until 2024 when there will be a sudden speeding up of the process.

In between 30 and 50 years, they concluded, summer sea ice will have vanished from almost the entire Arctic region.

Their finding may, however, already be out of date and something of an over-optimistic forecast, said Professor Chris Rapley, head of the British Antarctic Survey.

He said a recent study by the Global Carbon Project suggests emissions are rising more than twice as fast as in 2000 which is likely to speed up ice-loss even further.

"The study findings may be an under estimate of when the Arctic summer ice might be all gone," he said. "It could well be their assumptions are more optimistic than they might be."

He described the report as "worrying" but said it fitted into recent findings based on satellite observations of the speed at which ice is retreating.

Arctic ice is being hit by the double effects of loss of reflectivity and warmer currents being washed into the ocean.

Scientists have long realised that ice reflects heat and as the quantity reduces so, too, does the amount of heat that can be bounced away from the Earth.

However, the study team from the National Centre for Atmospheric Research in Colorado, US, and two US universities, identified warmer ocean currents as an additional factor to be considered.

Disappearing ice is already causing problems for the Polar Bear and it is likely to be driven to the brink of extinction unless it can find ways of adapting.

Other wildlife, including seals, are also likely to suffer, though not so badly but the removal of sea ice is likely to benefit a range of marine creatures, including cod, which could move in to the open waters.

For people the open waters are likely to lead to fresh opportunities, though the Inuit lifestyle would be damaged.

Tourist could open up to allow visitors Arctic cruises with cocktail parties over the North Pole that previously defied the best efforts of many explorers.

Oil companies would move in to tap resources previously protected by the ice and freight firms could use the ocean as a shortcut.

Winter ice will still remain because temperatures will plunge during the winter when there is no sun to heat up the region but it will melt faster each year because less will form.

The US study team modified one of the climate models used by the United Nation’s Intergovernmental Panel on Climate Change to establish what will happen to the ice as carbon emissions rise.

"We have already witnessed major losses in sea ice, but our research suggests that the decrease over the next few decades could be far more dramatic than anything that has happened so far," said Professor Marika Holland who led the study. "These changes are surprisingly rapid."

"As the ice retreats, the ocean transports more heat to the Arctic and the open water absorbs more sunlight, further accelerating the rate of warming and leading to the loss of more ice. This is a positive feedback loop with dramatic implications for the entire Arctic region."

This sounds pretty cool. I'd love to sail over the North Pole.

You'd think the Libs would be happy. According to the "Theory of Evolution" the Warmer climates in the history of the earth increased speciation and diversity.

Are these the same "experts" that can't predict the weather further than 72 hours in advance??

Did everyone hear that? Free ice at the North Pole! Get it while it's hot!

This will be a great boost to shipping.

The shipping cost savings could be enormous between Europe and Asia. Funny how that is not mentioned at all, isn't it.

Ex = something that once was.

Spurt = a drop of fluid coming out under pressure.

expert = a has been drip under pressure.

Not to worry, though. Democrats have it all under control. As soon as they take our liberties away, the earth's temperature will magically stabilize, proving once again, only they can save mankind. >>insert favorite eye rolling emoticon<<

I'm going to make lemonade out of lemons and consider it a real estate investment opportunity.

Yeah, and now we'll be able to have cocktail parties!

Good shot! Love the irony.

As we both know, however, the Lefty-loonies aren't interested at all in speciation or diversity. They are only interested in control of as many peoples' lives to the maximum degree possible (or, 'possible' as they see it).

Happy Christmas to you and yours!

We're dooooooooooooooooooooomed. And this is a problem, how exactly?

I'm sorry to hear that. I'm booking my cruise now.

Are these the same "experts" that were warning of the coming ice age in the 1970s? How often do you have to be proven wrong to get the "expert" label removed?

Cool. Then we can drill for oil.

Can they tell from Ice cores from the Arctic how long it has been covered with ice -- say only back to 1600s or 1300s or Iron Age when climate was significantly hotter in the world (and NOT due to man's CO2 output) ?????

Trapped CO2 subjected to Carbon 14 dating ??? If the ice is old shouldnt it go way back (enuf to get a good estimate via the radioisotope dating....)

Didn't the survey team abort last year because it was too cold and there was too much ice?
