As global warming thaws the Arctic, Russia is leading the rush to exploit the region’s resources. In late 2013, on a platform in the Pechora Sea, Gazprom became the first company to produce oil offshore in the Arctic, after jailing 30 Greenpeace protesters and confiscating their ship. On the east side of Yamal a partnership led by another Russian company, Novatek, is building a giant terminal to liquefy gas and export it to East Asia and Europe by ice-breaking tanker—though over time there may be less and less ice to break. ... Russia is not alone. More than a fifth of the world’s conventional oil and gas that has yet to be discovered lies above the Arctic Circle, according to a 2008 estimate by the U.S. Geological Survey, and the region is rich in other minerals too. ... Given the hype on both sides of the argument, what’s striking is how patchy the Arctic rush actually is. Few companies have dipped their toes into Arctic waters, and fewer still are making a profit. Last fall Royal Dutch Shell abruptly abandoned its multiyear, seven-billion-dollar effort to extract oil from the Chukchi Sea off Alaska after drilling a single unpromising hole. Record-low oil prices likely contributed to the decision. So did the astronomical costs of operating in a region where infrastructure is sparse, distances are huge, and the weather remains horrific.
