The Northern Sea Route across the top of Russia is clear, and has been for much of the summer.

Royal Dutch Shell won permission on Monday to start deep drilling at a Chukchi Sea exploration well, opening the way for the company to reach oil.

The U.S. Bureau of Safety and Environmental Enforcement granted Shell a modified drilling permit that had previously allowed the company to drill only the top section of the well, one of six that Shell plans for its Chukchi Sea Burger prospect...
