2016 Near-Record Low in Arctic Sea Ice

These Images Show Near-Record Low 2016 Arctic Sea Ice, Climate Central , By  September 15th, 2016   Arctic sea ice is one of the grandaddy’s of climate indicators. And this grandaddy isn’t doing so good these days.This year’s sea ice extent has bottomed out as the second lowest on record, according to the National Snow and Ice Data Center. It continues a troubling trend as rapidly warming air and water eats away at the briny, frozen mantle on the top of the planet.

 2016’s Arctic Sea Ice Melt Season in 9 Seconds

This year has been exceptional by many standards. March saw the lowest sea ice maximum ever recorded followed by a string of record low months. The Northwest Passage opened up, allowing a luxury cruise ship to travel from Anchorage to New York. And a freak storm in August turned ice thin and brittle near the North Pole.

Satellites show the last seven months of sea ice and reveal its steep decline this year. The late August breakup is particularly notable. Grist’s Amelia Urry compared the texture of sea ice near the North Pole to curdled milk or an exploded pillow (I’d go with broken glass personally, but to each their own)………

Most of what we tend to talk about with Arctic sea ice comes courtesy of satellites since they’re the most reliable way to monitor such a remote region. Recent research has reconstructed Arctic sea ice data back to 1850 using old ship logs, airplane survey and military records among other sources to provide a longer record than satellite data (though it does come with a little bit more uncertainty). What is certain is that there’s nothing in modern history like the recent string of low Arctic sea ice years we’ve seen.

Sea ice has declined precipitously across the Arctic, but particularly in the Beaufort and Chukchi Sea regions. In the coming decades, sea ice extent is only likely to keep shrinking and could reshape the region’s ecology, economy and ways of life for the plants, animals and people that call the region home. http://www.climatecentral.org/news/2016-low-arctic-sea-ice-20702
