The ice covered 1.74 million square miles on Friday, marking a low point for this summer, according to NASA and the National Snow and Ice Data Center in Boulder, Colo. Last summer, the sea ice covered only 1.59 million square miles, the lowest since record-keeping began in 1979.

Arctic sea ice, which floats on the ocean, expands in winter and retreats in summer. In recent years it hasn’t been as thick in winter.

Sea ice is crucial to worldwide weather patterns, both serving as a kind of refrigerator and reflecting the sun’s heat. Given recent trends, triggered by man-made global warming, scientists warn that within five to 10 years the Arctic could be free of sea ice in the summer.

Even though the sea ice didn’t retreat this year as much as last summer, “there was no real sign of recovery,” said Walt Meier of the snow and ice data center. This year was cooler and other weather conditions weren’t as bad, he said.

“We’re kind of in a new state of the Arctic basically, and it’s not a good one,” Meier said. “We’re definitely sliding towards a point where the summer sea ice will be gone.”
