Arctic winter sea ice extent is seventh lowest on record

Arctic sea ice has reached its maximum extent for the year, peaking at 14.78 million square kilometers on March 13. It is the joint seventh smallest winter maximum in the 40-year satellite record – tied with 2007.

Latest data shows sea ice extent hits record low at both poles

Arctic temperatures have finally started to cool off a bit after unseasonable warmth dominated the northern regions beginning in October 2016. Polar researchers say the record warmth could result in the third year in a row of record low sea ice extent.

Arctic sea ice extent hits record low for November

Boulder - This is the time of year that we should be seeing evidence that Arctic seas are refreezing in the long Polar night, but scientists say sea ice in the Arctic hit record lows for November.

Arctic's insanely warm temperatures are alarming, say scientists

The Arctic region of our world is in serious trouble, and its condition should raise alarm bells for everyone. Sea surface and air temperatures are extraordinarily high, and this will have consequences for us now and in the future.

2016 ties with 2007 for second lowest Arctic sea ice minimum

The Arctic hit its summer sea ice minimum on September 10 this year, with the total recorded at 4.14 million square kilometres (1.60 million square miles), making 2016 a statistical tie with the 2007 minimum for the lowest on record.

Arctic sea ice levels hit record low after warm January

Boulder - Usually at this time of the year, Arctic sea ice is building up to its yearly maximum, making the region almost impenetrable to all but the toughest icebreakers. However, January has been unusually warm, leaving the ice extent lower than average.

Underwater robot sheds new light on Antarctic sea ice

Cambridge - A collaborative effort involving scientific teams from the UK, U.S. and Australia has produced the first detailed, high-resolution 3-D maps of Antarctic sea ice with the help of an underwater robot.

Antarctic sea ice extent dumbfounds climate scientists

There is more sea ice in Antarctic Ocean waters today than has ever been seen since scientists began using satellites to record and map the extent in the 1970s. While this may reflect negatively on global warming, scientists can explain the phenomenon.

Sea ice extent at both poles has scientists shaking their heads

The earth's sea and ice cover is not a static thing, but changes continually. This year is a good example, with Antarctic sea ice extent setting a growth record, while the Arctic sea ice did better than 2012's record low sea ice extent.
