Melting Arctic Opens Up Northwest Passage

 A fabled sea route above North America linking the Pacific and Atlantic Oceans has become a reality thanks to global warming.

Scientists have confirmed that in August, Arctic sea ice shrank to its lowest levels since satellite measurements began monitoring the region nearly 30 years ago.

One consequence of this is that the Northwest Passage has opened up much earlier than expected.

“We’re several decades ahead of schedule right now,” said Mark Serreze, a senior scientist at the University of Colorado’s National Snow and Ice Data Center, which monitors the region.
