Antarctica is missing an Argentina-sized amount of sea ice – and scientists are scrambling to figure out why
As the Northern Hemisphere swelters under a record-breaking summer heat wave, much further south, in the depths of winter, another terrifying climate record is being broken. Antarctic sea ice has fallen to unprecedented lows for this time of year.
Every year, Antarctic sea ice shrinks to its lowest levels towards the end of February, during the continent’s summer. The sea ice then builds back up over the winter.
But this year scientists have observed something different.
In mid-July, Antarctica’s sea ice was 2.6 million square kilometers (1 million square miles) below the 1981 to 2010 average. That is an area nearly as large as Argentina or the combined areas of Texas, California, New Mexico, Arizona, Nevada, Utah, and Colorado
‘The game has changed’
The phenomenon has been described by some scientists as off-the-charts exceptional – something that is so rare, the odds are that it only happens once in millions of years.
