'Scary': After Abnormally Warm Winter, Arctic's Strongest Sea Ice Breaks Up for First Time on Record
Ice that's generally about 65 feet thick has become much thinner due to warming trends, allowing the unusually warm winds blowing through the region to push the ice apart
Aug 21, 2018
After abnormal heatwaves this year in the Arctic, the region's oldest and thickest sea ice has thinned out considerably--to the point of breaking up in recent days.
As the Guardian reported, the Norwegian Ice Service found this week that the ice cover in the area off the northern coast of Greenland has been at record low levels at least 14 days in the past month, sometimes reaching levels 40 percent lower than the average for this time of year.
\u201cThe #Svalbard #seaice area from the ice chart for 21st Aug 2018 is 111,968 sq km. This is 115,969 sq km below the 1981-2010 average. #Arctic\u201d— Norway Ice Service (@Norway Ice Service) 1534856727
\u201cThis is the lowest area for this day of the year in our records dating back to 1967.\u201d— Norway Ice Service (@Norway Ice Service) 1534856736
The new development is causing grave concerns among climate scientists regarding their previously-held beliefs about the Arctic's ice.
"Open water off the north coast of Greenland is unusual," Ruth Mottram of the Danish Meteorological Institute told the Guardian. "This area has often been called 'the last ice area' as it has been suggested that the last perennial sea ice in the Arctic will occur here."
Heatwaves last February and this month as well as warm winds have pushed ice that is generally about 65 feet thick away from Greenland's northern coast. Warming trends that have been maintained over the last 15 years, according to scientists, has made ice that's usually packed close together, much less stable.
Generally, "The ice there has nowhere else to go so it piles up," research scientist Walt Meier of the US National Snow and Ice Data Center told the Guardian. "However, that was not the case this past winter in February and March and now. The ice is being pushed away from the coast by the winds."
"It's a pretty dramatic indication of the transformation of the Arctic sea ice and Arctic climate," Meier added.
Another climate researcher, Thomas Lavergne of the Norwegian Meteorological Institute, called the findings "scary" on social media.
\u201cSo the open water / low concentration patch North for Greenland is still there (and slowly moving westward). Nice and scary. From https://t.co/jPx1JmNayA\u201d— Thomas Lavergne (@lavergnetho@fediscience.org) (@Thomas Lavergne (@lavergnetho@fediscience.org)) 1534153789
Scientists have traced the record-defying ice thinning back to a notable heatwave in February.
As Common Dreams reported, a weather station in northern Greenland usually registers temperatures of about -4 degrees Fahrenheit in February, but this year there were 10 days that month where warm winds and temperatures above freezing were recorded.
\u201cThe area of Arctic ice referred to as the "final northern holdout against the melting effects of a hotter planet" is breaking up more than ever before. This is because of abnormally high temperatures, worsened by human activity. \n#ThisIsClimateChange https://t.co/mpyXq7pByN\u201d— The Green Party (@The Green Party) 1534855652
An Urgent Message From Our Co-Founder
Dear Common Dreams reader, The U.S. is on a fast track to authoritarianism like nothing I've ever seen. Meanwhile, corporate news outlets are utterly capitulating to Trump, twisting their coverage to avoid drawing his ire while lining up to stuff cash in his pockets.

Our small but mighty team is a progressive reporting powerhouse, covering the news every day that the corporate media never will. Our mission has always been simple: To inform. To inspire. And to ignite change for the common good. Now here's the key piece that I want all our readers to understand: None of this would be possible without your financial support. That's not just some fundraising cliche. It's the absolute and literal truth. We don't accept corporate advertising and never will. We don't have a paywall because we don't think people should be blocked from critical news based on their ability to pay. Everything we do is funded by the donations of readers like you. Will you donate now to help power the nonprofit, independent reporting of Common Dreams? Thank you for being a vital member of our community. Together, we can keep independent journalism alive when it’s needed most. - Craig Brown, Co-founder |
