Sea Ice Gone A Month Early Along 300 Miles Of NW Alaska Coast

The Arctic's record-warm winter has allowed thousands of square miles of sea ice off Alaska to melt more than a month early, leaving the shoreline vulnerable to waves and exposing dark ocean water to absorb more heat from the sun.

The loss of ice in the Chukchi Sea will boost the regional temperature and could increase precipitation over nearby land, said Alaska-based climate scientist Rick Thoman.

As of May 24, the ice cover on the Chukchi Sea had melted away from the shore along a 300 mile stretch, from Point Hope all the way to Barrow, the northernmost town in the United States. Satellite and radar data show the ice-free area totaled about 54,000 square miles.

The huge area of open water off the coast is something you would normally see in early July, said Mark Serreze, director of the National Snow and Ice Data Center. The rapid disintegration of the Chukchi Sea ice is an "exclamation point" on a remarkable series of rapid fire Arctic changes, he said. "It's another sign that the Arctic is unraveling. We had heat waves in the central Arctic last winter, record-low winter sea ice coverage, and even periods of ice retreat when it should be growing. These extremes are moving from place to place," Serreze said.
