One thing Captain Bozanov did not encounter while towing an industrial barge 2,300 miles across the Arctic Ocean was solid ice blocking his path anywhere along the route. Ten years ago, he said, an ice-free passage, even at the peak of summer, was exceptionally rare.
But environmental scientists say there is now no doubt that global warming is shrinking the Arctic ice pack, opening new sea lanes and making the few previously navigable routes near shore accessible more months of the year. And whatever the grim environmental repercussions of greenhouse gas, companies in Russia and other countries around the Arctic Ocean are mining that dark cloud’s silver lining by finding new opportunities for commerce and trade.
Oil companies might be the most likely beneficiaries, as the receding polar ice cap opens more of the sea floor to exploration. The oil giant Exxon Mobil recently signed a sweeping deal to drill in the Russian sector of the Arctic Ocean. But shipping, mining and fishing ventures are also looking farther north than ever before.
