Scientists expressed shock and alarm this weekend amid extreme high temperatures near both of the Earth's poles--the latest signs of the accelerating planetary climate emergency.
"This event is completely unprecedented and upended our expectations about the Antarctic climate system."
Temperatures in parts of Antarctica were 50degF-90degF above normal in recent days, while earlier this week the mercury soared to over 50degF higher than average--close to the freezing mark--in areas of the Arctic.
Stefano Di Battista, an Antarctic climatologist, tweeted that such record-shattering heat near the South Pole was "unthinkable" and "impossible."
"Antarctic climatology has been rewritten," di Battista wrote.
The joint French-Italian Concordia research station in eastern Antarctica recorded an all-time high of 10degF on Friday. In contrast, high temperatures at the station this time in March average below -50degF.
Jonathan Wille, a researcher studying polar meteorology at Universite Grenoble Alpes in France, toldThe Washington Post that "this event is completely unprecedented and upended our expectations about the Antarctic climate system."
"This is when temperatures should be rapidly falling since the summer solstice in December," Wille tweeted. "This is a Pacific Northwest 2021 heatwave kind of event," he added, referring to the record-breaking event in which parts of Canada topped 120degF for the first time in recorded history. "Never supposed to happen."
Walt Meier, a senior research scientist at the National Snow and Ice Data Center in Boulder, Colorado, told USA Today that "you don't see the North and the South [poles] both melting at the same time" because "they are opposite seasons."
"It's definitely an unusual occurrence," he added.
As Common Dreams has reported, the Arctic has been warming three times faster than the world as a whole, accelerating polar ice melt, ocean warming, and other manifestations of the climate emergency.
"Looking back over the last few decades, we can clearly see a trend in warming, particularly in the 'cold season' in the Arctic," Ruth Mottram, a climate scientist with the Danish Meteorological Institute, told the Post. "It's not surprising that warm air is busting through into the Arctic this year. In general, we expect to see more and more of these events in the future."
