Arctic sea ice shrank to the lowest winter extent ever recorded, according to data released today by the US-based National Snow and Ice Data Center. The record-low ice level follows earlier news that 2014 was the warmest year since record keeping began.
An unusually warm February in parts of Alaska and Russia contributed to the record ice low. The winter reach of Arctic ice decreased 1.1 million square kilometres compared to the average maximum from 1981 to 2010. This represents an area more than twice the size of Sweden.
“This is not a record to be proud of. Low sea ice can create a series of reactions that further threaten the Arctic and the rest of the globe,” said Alexander Shestakov, Director, WWF Global Arctic Programme.
Arctic waters freeze during the dark winter with sea ice reaching its maximum extent in March. The record announced today is a sign of thin, slow-growing ice. Less ice available to reflect the sun’s heat means the sea absorbs more warmth, further worsening ice conditions over time.
“Today’s chilling news from the Arctic should be a wakeup call for all of us,” said Samantha Smith, Leader, WWF Global Climate and Energy Initiative. “Climate change won’t stop at the Arctic Circle. Unless we make dramatic cuts in polluting gases, we will end up with a climate that is unrecognizable, unpredictable, and damaging for natural systems and people.”
