This trip! Alaska to Iceland or even London....

See - http://news.yahoo.com/s/nm/20070915/bs_nm/arctic_passage_dc_4

LONDON (Reuters) - The Arctic's Northwest Passage has opened up fully because of melting sea ice, clearing a long-sought but historically impassable route between Europe and Asia, the European Space Agency said.

Sea ice has shrunk in the Arctic to its lowest level since satellite measurements began 30 years ago, ESA said, showing images of the now "fully navigable" route between the Atlantic and the Pacific.

A shipping route through the Northwest Passage in the Canadian Arctic has been touted as a possible cheaper option to the Panama Canal for many shippers.

"We have seen the ice-covered area drop to just around 3 million square km," said Leif Toudal Pedersen of the Danish National Space Centre, describing the drop in the Arctic sea ice as "extreme."

The figure was about 1 million sq km (386,870 sq miles) less than previous lows in 2005 and 2006, Pedersen added.

The Northeast Passage through the Russian Arctic remained partially blocked, but in the light of the latest developments it may well open sooner than expected, Pedersen said.

Polar regions are very sensitive to climate change, ESA said, noting that some scientists have predicted the Arctic would be ice free as early as 2040.

Almost all experts say global warming, stoked by human use of fossil fuels, is happening about twice as fast in the Arctic as elsewhere on the planet. Once exposed, dark ground or sea soak up far more heat than ice and snow.

September and March generally mark the annual minimum and maximum extent respectively of Arctic sea ice.

The ESA announcement on its Web site came amid a scramble for sovereignty rights in the Arctic.

Russia, which recently planted its national flag on the seabed beneath the ice of the North Pole, has been staking its claim to a large chunk of the resource-rich Arctic region.

Countries such as Russia are hoping for new shipping routes or to find oil and gas.

Canada has also been pressing its Arctic sovereignty claim and has announced plans for a deep-water port at Nanisivik near the eastern entrance of the Northwest Passage, which will allow it to refuel its military patrol ships.

Roger --
Interesting article but -- Brrrr -- how about suggesting Chris (Orca) head for Tahiti?

About two weeks ago there was an article in the paper about the rapid loss of ice over Greenland. Apparently there is enough ice in Greenland to raise sea level 23 feet (!), although this was not the main point of the article.

With the ice receding, a new issue arises -- who owns the oil rights under this newly accessible area?

Is it just me, or do others detect some level of irony in the preceding sentence?

Let's burn more oil, so we can melt off the ice, so we can get more oil!

There is no credible scientist or climatologist that claims that. Al Gore started that misconception and it seems to have been repeated so many times, many people actually believe it.

A little critical thinking with some math and a little research on the web about Greenland will prove nothing even close to this will happen, when all of Greenland’s ice has melted.
