The century-old Panama Canal has a major shortcoming: New ships are too long, too deep and too wide to fit through it. by 2015, 40 percent of the world's fleet will have outgrown the roughly 50-milelong passageway that is a key artery for goods headed from Asia to Europe and the U.S. Gulf and East coasts. Since 2008, the Panama Canal Authority has been leveling hillsides, excavating miles of new access channels to make room for the so-called post-Panamax ships.

For a few short weeks last September, the Northwest and Northeast passages through the Arctic Ocean were simultaneously ice-free from end to end, the first such clearing in the time that satellites have monitored the region. Merchants have long sought routes through the ice packed waters that link the pacific and Atlantic. But researchers at the Naval postgraduate school in Monterey, California, say that we could now see an entire Arctic Ocean, not just passages along the coasts, with icefree summers, as soon as 2016.
