One Week After Frank, Arctic Sea Ice Hits New Record Lows

Extreme weather and climate change. The plight of human civilization facing loss of coastlines, stable climates, and predictable growing seasons. The plight of the polar bear. How are they all linked? Well, for one, it now appears that one of the most powerful storms to strike Iceland — an extraordinarily intense 928 mb low pressure system dubbed Frank by the UK Met Office — has played its hand in helping to drive Arctic sea ice to new daily record lows.

The storm, associated with a powerful high amplitude wave in the Jet Stream, aided in shoving some of the warmest temperatures ever recorded over the North Pole. Setting off a rare period of above freezing temperatures during polar night, this extreme weather event dumped an unprecedented amount of heat into the Arctic during what is typically its coldest season.

It’s the kind of atmospheric heat engine whose climate and weather altering impacts I discussed with Dr. Jeff Masters, Dr Steven Amstrup, and the hosts of Voice of America’s news show #Hashtag — Michael Lipin and Andrew Palczewski — today. The kind of extreme events that become more and more common as the world warms up, dumping an inordinate amount of latent heat into storms as they form and intensify.

But this particular event’s far-ranging impact could also be seen in a warm temperature shift for the High Arctic during Winter. A shift that brought with it a flatlining of Arctic sea ice accumulation.

Typically, during December and on through mid-April, Arctic sea ice area and extent values continue to rise. The cold of polar night settles in over a broad area of water. Bereft of the heating rays of the sun and typically plunged into temperatures well below freezing, the ocean surface becomes covered in an expanding cap of ice. There it provides a stable environment for so many Arctic creatures that have made that place their home. But it has also helped to provide the stable climate of the Holocene — in which for more than 10,000 years human beings and our civilizations have been able to thrive.

This year’s massive Arctic warm-up, in association with Frank, appears to have stranded that essential ice accumulation in dead stop. And as of January 4th, according to the National Snow and Ice Data Center, Arctic sea ice extent totals remained at 12.8 million square kilometers. That’s about 90,000 square kilometers below the previous record daily low set on the same day just five years ago during the Winter of 2011. It’s also an extent value fully 1 million square kilometers, an area the size of Texas and Montana combined, below the already depleted 1981 to 2010 average.

Cryosphere Today showed Arctic sea ice area also following that ominous flatline pattern — hitting 12.23 million square kilometers in coverage or the second lowest area on record for the day.

Continued warmer than normal temperatures in the Arctic in the range of 3 to 3.5 C above average for the region may well continue to drive this sea ice flat line over at least the next couple of days, pushing area measures into new record low readings even as extent continues to break records.

Failure to freeze during Winter is one of the driving factors of major Arctic sea ice declines during Summer (often called Winter power over at the Arctic Sea Ice Blog). So with sea ice hitting new lows for a, much warmer than normal cold season, we may need to watch out for potential new major losses come summer time. And that’s bad news for everyone — seals, walruses, polar bears, human beings and for many of the creatures below the Arctic Circle that rely on that frozen region for the maintenance of the climate they evolved and adapted to live in. Dr. Steven Amstrup, who has been a fearless advocate for the innocent creatures most likely to be impacted early by human-forced warming of the Arctic, I’m pretty sure, would agree.
