Record ice low could quicken Arctic thaw
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.”
WWF and others have identified special places around the Arctic that will be increasingly important in a future with less ice. These regions, like the Last Ice Area, represent the best hope for ice-associated life.
“An enormous web of life depends on Arctic sea ice. With sea ice under increasing threat, Arctic states must quickly create a network of resilient marine areas around the pole,” said Shestakov.
The proportion of thick Arctic ice that lasts multiple years has dwindled over the past two decades. A recent study shows that Arctic sea ice has thinned by 65 per cent since 1975, leaving ice that is more susceptible to melting.
