‘Unthinkable’: Scientists Shocked as Polar Temperatures Soar 50 to 90 Degrees Above Normal
“With everything going on in the world right now, the dual polar climate disasters of 2022 should be the top story.” – Prof. Eliot Jacobson
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.
Temperatures in parts of Antarctica were 50°F-90°F above normal in recent days, while earlier this week the mercury soared to over 50°F higher than average—close to the freezing mark—in areas of the Arctic.
“Antarctic climatology has been rewritten,” di Battista wrote.
The joint French-Italian Concordia research station in eastern Antarctica recorded an all-time high of 10°F on Friday. In contrast, high temperatures at the station this time in March average below -50°F.
Record heat in the Arctic is driving an early melt season and crushing 2022 sea-ice extent: current rank now #4. The Antarctic is even worse.— Prof. Eliot Jacobson (@EliotJacobson) March 17, 2022

Jonathan Wille, a researcher studying polar meteorology at Université Grenoble Alpes in France, told The 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 120°F for the first time in recorded history. “Never supposed to happen.”
Scientists analysed sea surface temperatures over the last 150 years, which have risen because of global heating. They found that extreme temperatures occurring just 2% of the time a century ago have occurred at least 50% of the time across the global ocean since 2014.
The study’s authors say the likelihood of higher-latitude tropical storms fueled by human-caused global heating “poses profound risks to the planet’s most populous regions.”
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.
50 degrees above normal in the North Pole this week, and 50 to 90 degrees above normal in Antarctica. Good lord. https://t.co/bSrodCJdei— Brooke Jarvis (@brookejarvis) March 18, 2022
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.”
