The Arctic Sea ice has melted enough to open a shipping lane north of Canada. It isn’t totally clear, but is clear enough to encourage shippers to use the northern route rather than the Panama Canal or going to the other extreme around the southern tip of South America.
The rate of ice loss for July 2015 averaged 101,800 square kilometers (39,300 square miles) per day, compared to 97,400 square kilometers (37,600 square miles) in 2012 and 86,900 square kilometers (33,500 square miles) per day in the long-term 1981 to 2010 average. – National Snow & Ice Data Center
Bad news for the Arctic is good news for shipping, a small benefit.
