Ice covering the Arctic Ocean reached the second-lowest level recorded for this time of year after July temperatures spiked in areas around the North Pole.
The rate of ice loss in the region is a crucial indicator for the world’s climate and a closely-watched metric by bordering nations jostling for resources and trade routes. This month’s melt is tracking close to the record set in July 2012, the Colorado-based National Snow & Ice Data Center said in a statement.
This year’s heatwave in the Arctic Circle has led to record temperatures in areas of Alaska, Canada and Greenland, extending long-term trends of more ice disappearing. Ice flows are melting faster than average rates observed over the last three decades, losing an additional 20,000 square kilometers (12,427 miles) of cover per day -- an area about the size of Wales.
