The US National Oceanic and Atmospheric Association (NOAA) has just released it's 2012 report card on the conditions of snow and ice cover in the Arctic region.

The region, located above the Arctic Circle, or 66 degrees north latitude, suffered record low snow cover and sea ice, while at the same time seeing warmer-than-average sea temperatures, increased green space and vegetation growing seasons, and a boom in Sun-driven plankton production.

“The Arctic is changing in both predictable and unpredictable ways, so we must expect surprises,” said Jane Lubchenco, Ph.D., under secretary of commerce for oceans and atmosphere and NOAA administrator, in a statement at the American Geophysical Union in San Francisco. “The Arctic is an extremely sensitive part of the world and with the warming scientists have observed, we see the results with less snow and sea ice, greater ice sheet melt and changing vegetation.”

As a consequence of the changes, the Arctic fox is close to extinction in Northern Europe, NOAA said.

The agency published a video highlighting some of the findings of the report card, which was prepared by 141 authors in 15 countries:

     

One of the most dramatic examples of the record year of losses that the Arctic saw in 2012 was the nearly complete surface melt of the Greenland ice sheet over a stunningly quick 10 days in July.  

NOAA noted that the snow cover loss was the third record low for North America in five years and the fifth consecutive record low for Europe and Asia.

Sea ice, too plummeted to its smallest minimum coverage area yet — 1.3 million square miles — or 18 percent below the prior record low of 1.65 million square miles in 2007.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
