From Seattle Times.
Amid a record hot summer in large parts of Northern Hemisphere, beset by devastating fires, floods and hurricanes, Antarctica was mired in a deep, deep freeze. That’s typically the case during the southernmost continent’s winter months, but 2021 was different.
The chill was exceptional, even for the coldest location on the planet.
The average temperature at the Amundsen-Scott South Pole Station between April and September, a frigid minus-78 degrees (minus-61 Celsius), was the coldest on record, dating back to 1957. This was 4.5 degrees lower than the most recent 30-year average.
We first learned of this record through a tweet from Stefano Di Battista, who has published research on Antarctic temperatures. The legitimacy of Di Battista’s information was confirmed by Richard Cullather, a research scientist at NASA’s Global Modeling and Assimilation Office.
The temperature averaged over September was also the coldest on record at South Pole, wrote David Bromwich, a polar researcher at Ohio State University, in an email.
The extreme cold over Antarctica helped push sea ice levels surrounding the continent to their fifth-highest level on record in August, according to the National Snow and Ice Data Center.
Extraordinarily cold weather continues to grip the Antarctic Plateau. Maximiliano Herrera, a climatologist who monitors world weather extremes, tweeted that temperature at Russia’s Vostok Station sunk to minus-110.9 degrees (minus-79.4 Celsius) on Thursday (Sept. 30), which was just one degree (0.6 Celsius) from the world’s lowest temperature on record during October.
