This just can't be happening, they must have used trick photography,

OTTAWA ? The multiyear ice covering the Arctic Ocean has effectively
vanished, a startling development that will make it easier to open up
polar shipping routes, an Arctic expert said on Thursday.

Vast sheets of impenetrable multiyear ice, which can reach up to 80
meters (260 feet) thick, have for centuries blocked the path of ships
seeking a quick short cut through the fabled Northwest Passage from
the Atlantic to the Pacific. They also ruled out the idea of sailing
across the top of the world.

But David Barber, Canada's Research Chair in Arctic System Science at
the University of Manitoba, said the ice was melting at an
extraordinarily fast rate.

"We are almost out of multiyear sea ice in the northern hemisphere,"
he said in a presentation in Parliament. The little that remains is
jammed up against Canada's Arctic archipelago, far from potential
shipping routes.

Scientists link higher Arctic temperatures and melting sea ice to the
greenhouse gas emissions blamed for global warming.

Barber spoke shortly after returning from an expedition that sought --
and largely failed to find -- a huge multiyear ice pack that should
have been in the Beaufort Sea off the Canadian coastal town of
Tuktoyaktuk.

Instead, his ice breaker found hundreds of miles of what he called
"rotten ice" -- 50-cm (20-inch) thin layers of fresh ice covering
small chunks of older ice.

"I've never seen anything like this in my 30 years of working in the
high Arctic ... it was very dramatic," he said.

"From a practical perspective, if you want to ship across the pole,
you're concerned about multiyear sea ice. You're not concerned about
this rotten stuff we were doing 13 knots through. It's easy to
navigate through."

Scientists have fretted for decades about the pace at which the Arctic
ice sheets are shrinking. U.S. data shows the 2009 ice cover was the
third-lowest on record, after 2007 and 2008.

An increasing number of experts feel the North Pole will be ice free
in summer by 2030 at the latest, for the first time in a million
years.

"I would argue that, from a practical perspective, we almost have a
seasonally ice-free Arctic now, because multiyear sea ice is the
barrier to the use and development of the Arctic," said Barber.

Fresh first-year ice always forms in the Arctic in the winter, when
temperatures plunge far below freezing and the North Pole is not
exposed to the sun.

Shipping companies are already looking to benefit from warming waters.
This year two German cargo ships successfully navigated from South
Korea along Russia's northern Siberia coast without the help of
icebreakers.

The Arctic is warming up three times more quickly than the rest of the
Earth, in part because of the reflectivity, or the albedo feedback
effect, of ice.

As more and more ice melts, larger expanses of darker sea water are
exposed. These absorb more sunlight than the ice and cause the water
to heat up more quickly, thereby melting more ice.

Barber said the ice was now being melted both by rays from the sun as
well as from below by the warmer water.

Scientists are also seeing more cyclones, which pick up force as they
absorb heat from the warmer water. The cyclones help generate waves
that break up ice sheets and also dump large amounts of snow, which
has an insulating effect and prevents the ice sheets from thickening.

After a long search, Barber's ice breaker finally found a 16-km (10-
mile) wide floe of multiyear ice that was around 6 to 8 meters (20-26
feet) thick. But as the crew watched, the floe was hit by a series of
waves, and disintegrated in five minutes.

"The Arctic is an early indicator of what we can expect at the global
scale as we move through the next few decades ... So we should be
paying attention to this very carefully," Barber said

Until we are serious about Nukes, and other options that won't serve to
make Al Gore rich, you can say all you want, but I won't believe you are
really serious about solving the problem...- Hide quoted text -

That was kind of Harryesque! How do you know whether or not I'm
serious about solving ANY given problem?

Cause you fight for it here every day...
