Though the Arctic is often pictured as a vast white wasteland, scientists believe a thin layer of soot -- mostly invisible -- is causing it to absorb more heat. They want to find out if that's the main reason for the recent rapid warming of the Arctic, wh

    So now we have to deal with Global sooting, and are going to soot cap and trade?

    Soot is carbon.

    Soot, or black carbon, is produced by auto and truck engines, aircraft emissions, burning forests and the use of wood- or coal-burning stoves.

    He's losing all his ice too. Replace soot with salt. Does it seem far fetched now? Maybe, because you've probably never bought a big bag of it to de-ice your front steps.

    Pop me a memo when freighters and tankers start transiting the 'Northwest Passage'. :wink:

    Well you got your wish.


    Sought by explorers for centuries as a possible trade route, it was first navigated by Roald Amundsen in 1903–1906. Until 2009, the Arctic pack ice prevented regular marine shipping throughout most of the year, but climate change has reduced the pack ice, and this Arctic shrinkage made the waterways more navigable.

    'More navigable' is still not navigable and there are no cargo lines or tank lines with runs scheduled for this year. Also, Canada has eleven international ports and not a one of them is above the ice line.

    Maybe. But for right now the fact is that it is not a recognized international port for Canada.

    Maybe. But for right now the fact is that it is not a recognized international port for Canada.

    The Churchill Gateway Development Corporation is pleased to announce that for the second year in a row, ocean shipments from Russia have arrived at the Port of Churchill.

    A Murmansk Shipping Company vessel, the Kapitan Sviridov, was the first Russian ship to unload a shipment of fertilizer imported by Farmers of North America in 2007. The port of Churchill successfully built on the success of 2007 and achieved two 9000 metric ton shipments of inbound fertilizer in 2008. These shipments originated in Kaliningrad, Russia purchased by Farmers of North America (FNA) of Saskatoon, SK.

    The fertilizer has been sold throughout western and central Canada. The shipments once again clearly demonstrated the viability of the Arctic Bridge concept linking Churchill with Russian ports and are the result of extensive work to diversify the commodity base of the port.


    It was once owned by the Government of Canada but was sold in 1997 to the American company OmniTRAX to run privately.
