Antarctica's last six months were the coldest on record.
For the polar darkness period, from April through September, the average temperature was -60.9 degrees Celsius (-77.6 degrees Fahrenheit), a record for those months," the National Snow and Ice Data Center (NSIDC) said.
For the entire Antarctic continent, the winter of 2021 was the second-coldest on record, with the "temperature for June, July, and August 3.4 degrees Celsius (6.1 degrees Fahrenheit) lower than the 1981 to 2010 average at -62.9 degrees Celsius (-81.2 degrees Fahrenheit)," according to a new report from the NSIDC.
"This is the second-coldest winter (June-July-August months) on record, behind only 2004 in the 60-year weather record at Amundsen-Scott South Pole Station[."]
If human activity causes warming, the period of 1940-1975 should have caused quite a bit of warming. I should think the massive movements of troops, equipment, etc. would have warmed things up. Not to mention atomic bombs and testing. Battleships firing guns, artillery, and every other thing involved in a world war. Strange.
