Has Arctic ice loss reached a tipping point?

Faint hopes for recovery in the Arctic are crushed his month after sea ice shrank to its fourth lowest level on record, federal scientists said.

After hitting its summer minimum last week, the Arctic had 1.7 million square miles of sea ice, down 240,000 square miles from 2014. This difference is the size of California, New York, and Maryland combined.

The winter maximum extent of sea ice has also decreased in the Arctic, reported The Christian Science Monitor.
