Antarctica's winter is now 50F hotter than it used to be
A record-breaking heat wave unfolding at what should be the coldest time in Earth’s coldest place has scientists concerned about what it could mean for the future health of the Antarctic continent, and the consequences it could inflict for millions of people across the globe.
Summerlike heat in the dead of winter – even if much of the continent is still below freezing – is an alarming development for a place more capable than any other of generating catastrophic sea level rise as fossil fuel pollution continues to drive global temperatures upward. “I’m sure more (impacts) will emerge with time as we understand (this heat wave) better, but at the moment, it’s just a case of astonishment really, what we’re seeing,” Thomas Bracegirdle, deputy science leader for the British Antarctic Survey’s Atmosphere, Ice and Climate team, said. West Antarctica and its Thwaites “Doomsday” Glacier have been a major focus of scientific research in recent years due to the catastrophic impact its collapse would have on sea level rise.
