NOAA released the 2012 installment of the annual Arctic Report Card on December 5, 2012, as part of the American Geophysical Union's fall meeting.

It was developed by the NOAA Climate.gov team in cooperation with Arctic Report Card authors and other Arctic experts.

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.

At the edge of southern Louisiana sits Port Fourchon—the hub through which 20 percent of our nation’s oil and gas supplies are distributed to the rest of the country. The only road leading to and from this major port is the Louisana-1 Highway. A drive down the LA-1 through a vulnerable but vibrant coastal landscape shows what is at stake if ‘America’s longest main street’ fails to stay above water.

Since the mid-1950s, easy-to-serve, portion-controlled fish sticks have regularly found their way onto U.S. dinner tables and into school lunches. The past decade, however, has given fishermen and scientists a preview of the challenges they may face in keeping fish sticks on the menu as the planet gets warmer.

Data from 2010 indicate that mountain glaciers predominantly lost mass, and preliminary data from 2011 indicate a continuation of the same long-term trend.

In 2011, annual snow cover extent over Northern Hemisphere continents (including the Greenland ice sheet) averaged 24.7 million square kilometers, which is 0.3 million square kilometers less than the long-term average.
