Peter Apps in Reuters: This year's frenzy of oil and gas exploration in newly accessible Arctic waters could be the harbinger of even starker changes to come. If, as many scientists predict, currently inaccessible sea lanes across the top of the world become navigable in the coming decades, they could redraw global trading routes -- and perhaps geopolitics -- forever.This summer will see more human activity in the Arctic than ever before, with oil giant Shell engaged in major exploration and an expected further rise in fishing, tourism and regional shipping. But that, experts warn, brings with it a rising risk of environmental disaster not to mention criminal activity from illegal fishing to smuggling and terrorism.
"By bringing more human activity into the Arctic you bring both the good and the bad," Lt Gen Walter Semianiw, head of Canada Command and one of Ottawa's most senior military officers responsible for the Arctic, told an event at Washington DC think tank the Centre For Strategic and International Studies last week. "You will see the change whether you wish to or not."
With indigenous populations, researchers and military forces reporting the ice receding faster than many had expected, some estimates suggest the polar ice cap might disappear completely during the summer season as soon as 2040, perhaps much earlier....
