Quick, More Carbon Dioxide! Oh, wait, CO2 is barely a greenhouse gas...

Thanks, Global Warming!
By Chris Mayer

"The sea route running along the Arctic coastline of North America, normally clogged with thick ice - is nearly ice free for the first time since records began." - "Northwest Passage Is Now Plain Sailing," Guardian Unlimited, Aug. 28
[Emphasis added]

[Why] the sudden interest in the Arctic? There are two big reasons. First, thanks to global warming, deposits of natural resources once layered over in impenetrable ice are now easier to get at. Second, thanks to melting ice, some previously icebound shipping lanes are opening up. [...]

As a treasure trove of natural resources, the Arctic boggles the mind. By some informal estimates, the region holds 25% of the world's undiscovered oil and gas. It could also hold massive amounts of crystallized methane - another potential fuel source. More formal surveys are under way by the Arctic lottery hopefuls. So in time, we'll know more about what Mother Nature has cooked up in the oven beneath the icy Arctic crust.

Minerals galore also lie untouched below the cold blue polar sea. One day, the region could be home to the undersea mining of copper, zinc, cobalt and diamonds.

In truth, these resources are still a long way from being developed. The climate is incredibly harsh, and easier-to-get-at resources still exist on the fringes of the Arctic. As an oil and gas story, this one has a long fuse.

The Arctic thaw's more immediate and bigger impact will be as a shipping lane. Since Aug. 21, the Northwest Passage has been open to navigation and free of ice for the first time. "Analysts... confirm that the passage is almost completely clear and that the region is more open than it has ever been since the advent of routine monitoring in 1972," reports the U.S. National Snow and Ice Data Center.

The fabled Northwest Passage through the Arctic Ocean connects the Pacific and Atlantic oceans along the northern coast of North America. To pass through here from China on your way to Europe is about 5,000 miles shorter than going through the Panama or Suez canals.

As the Financial Times observes, "A ship traveling at 21 knots between Rotterdam and Yokohama takes 29 days if it goes via the Cape of Good Hope, 22 days via the Suez Canal and just 15 days if it goes across the Arctic Ocean."

An oil tanker could make the trip from the Russian port city of Murmansk to the east coast of Canada in a week by crossing the Arctic Ocean. That is about half the time it takes to get an oil tanker from Abu Dhabi to Galveston, Texas. [...]

More than 90% of all goods in the world, measured by tonnage, make their way by sea. [...] In recent years, the volume of container shipments has grown 5-7% annually - basically, doubling every 10-15 years.

The ships carrying those containers are getting bigger, and the old canals can't hold these new seafaring beasts of burden as they once did. The Suez Canal can still handle the largest current container ships, but not the next generation.

The Panama Canal is even smaller. It's too small for ships that are now common on longer shipping routes. Panama plans to deepen its channels and make them wider. But even so, the new Panama Canal won't be able to service the next generation of ships.

So it looks like the world will have a new navigable ocean. The effects on trade could be immense. Much shorter shipping distances and quicker shipping times will lower the cost of doing business. It could lead to big increases in trade and, certainly, a major shift in sea lanes.

A freer-flowing Arctic Ocean would also bring fish stocks north - with fishing fleets not far behind. It could mean a new boom in fishing for salmon, cod, herring and smelt...
