January 2014 was remarkably mild across nearly all of Alaska, resulting in this January ranking among the  “top ten” warmest on record for many Alaskan communities according to preliminary analyses.

October in Alaska this year was more like September, with warmth and rain in place of autumn chill and snow. Wind anomalies related to unusual pressure patterns conspired to bring a steady stream of warm, wet air from southerly latitudes into Alaska.

For much of Alaska, lack of snow, soaking rains, and record-warmth have made October feel more like September.

Since 2002, Octobers in Barrow, Alaska—America's northernmost town—are regularly near the warmest on record, thanks to the retreat of sea ice. The warming hinders traditional hunting activities, makes the town more vulnerable to storm surge flooding, and thaws the frozen ground to greater depths, which destabilizes roads, house foundations, and traditional underground freezers.

Shallow melt ponds on the surface of consolidated sea ice act as skylights that promote massive under-ice phytoplankton blooms. These under-ice blooms may boost estimates of Arctic phytoplankton productivity by a factor of 10.

Ocean acidification is driving changes in waters vital to Alaska’s valuable commercial fisheries and subsistence way of life, according to new NOAA-led research that will be published online in...
