Global Warming May Open Northwest Passage
Arctic ice has shrunk to the lowest level on record, new satellite images show, raising the possibility that the Northwest Passage that eluded famous explorers will become an open shipping lane.
The European Space Agency said nearly 200 satellite photos this month taken together showed an ice-free passage along northern Canada, Alaska and Greenland, and ice retreating to its lowest level since such images were first taken in 1978.
The waters are exposing unexplored resources, and vessels could trim thousands of miles from Europe to Asia by bypassing the Panama Canal. The seasonal ebb and flow of ice levels has already opened up a slim summer window for ships.
Leif Toudal Pedersen, of the Danish National Space Center, said that Arctic ice has shrunk to some 1 million square miles. The previous low was 1.5 million square miles, in 2005.
"The strong reduction in just one year certainly raises flags that the ice (in summer) may disappear much sooner than expected," Pedersen said in an ESA statement posted on its Web site Friday.
Pedersen said the extreme retreat this year suggested the passage could fully open sooner than expected - but ESA did not say when that might be. Efforts to contact ESA officials in Paris and Noordwik, the Netherlands, were unsuccessful Saturday.
A U.N. panel on climate change has predicted that polar regions could be virtually free of ice by the summer of 2070 because of rising temperatures and sea ice decline, ESA noted.
Russia, Norway, Denmark, Canada and the United States are among countries in a race to secure rights to the Arctic that heated up last month when Russia sent two small submarines to plant its national flag under the North Pole. A U.S. study has suggested as much as 25 percent of the world's undiscovered oil and gas could be hidden in the area.
Environmentalists fear increased maritime traffic and efforts to tap natural resources in the area could one day lead to oil spills and harm regional wildlife.
Until now, the passage has been expected to remain closed even during reduced ice cover by multiyear ice pack - sea ice that remains through one or more summers, ESA said.
Researcher Claes Ragner of Norway's Fridtjof Nansen Institute, which works on Arctic environmental and political issues, said for now, the new opening has only symbolic meaning for the future of sea transport.
"Routes between Scandinavia and Japan could be almost halved, and a stable and reliable route would mean a lot to certain regions," he said by phone. But even if the passage is opening up and polar ice continues to melt, it will take years for such routes to be regular, he said.
"It won't be ice-free all year around and it won't be a stable route all year," Ragner said. "The greatest wish for sea transportation is streamlined and stable routes."
"Shorter transport routes means less pollution if you can ship products from A to B on the shortest route," he said, "but the fact that the polar ice is melting away is not good for the world in that we're losing the Arctic and the animal life there."
The opening observed this week was not the most direct waterway, ESA said. That would be through northern Canada along the coast of Siberia, which remains partially blocked.

The Medieval Optimum made it easier to live up North. (Wonder why a former Senator from Tennessee dislikes global warming?) The population in Scandinavia exploded. Then, when the Little Ice Age began, the Vikings became politically less important. The Viking settlements in Greenland died off.
PS: The Medieval Optimum was not caused by sport-utility vehicles in North America.
Think of the greenhouse emissions that will be saved by using this new Northwest Passage versus going all the way down through the Panama Canal!
You liberals are always so negative!
...
Let us zero on the items we see, growing acid levels in soils of the world, growing rates of asthma among chidren, visible signs of growing accumulations of soot on buildings etc, These are the most important needs for changing what fuels we use how we convert these to energy and how we conserve energy.
dumbazz, your own post proves errors abound.
No global warming? The proof is?
Yes global warming? The proof is?
Obviously, the damm research was in ERROR.
To bad those smart idiots were to stupid to ERROR on the safe side.
Same is true with global warming.
To bad people are to selfish to error on the safe side.
meanwhile, enjoy the ski slopes.
%u201CIt won''t be ice-free all year around and it won''t be a stable route all year,%u201D
--but apparently we can wish it would or could be...
Let''s put it this way, if someone told you that they heard that there was a certain kid that was going to be at your kids school tomorrow and they were going to kill your kid and you knew who this kid was and in your mind you could not EVER believe that kid would do something like that, would you send your kid to school? Or would you keep your kid home and rather be safe that sorry.
