Arctic Melt Opens Northwest Passage

Climate models had projected the passage would eventually open as warming temperatures melted the Arctic sea ice—but no one had predicted it would happen this soon.
“We’re probably 30 years ahead of schedule in terms of the loss of the Arctic sea ice,” said Mark Serreze, a senior scientist at the National Snow and Ice Data Center (NSIDC) in Boulder, Colorado.
The Northwest Passage was open 110 years ago.
It isn’t going to be open this year, as it is clogged with multi-year ice. According to Hansen, Amundsen navigated the Northwest passage during the coldest years on record.
