Antarctica set a third All-Time Record for sea ice extent while the US federal government was “shutdown”. Data here.
The first All-Time Record was September 14th with 19.51234 million sq km. (I am using all the digits for a good reason)
The 2nd All-Time Record was September 21 with 19.51394 million sq km. – only 1600 sq km higher.
Then the shutdown happened and all the data I use was frozen at September 30th. Today the data was updated.
The 3rd All-Time Record was set on October 2nd with 19.57088 million sq km.
Here is a portion of the latest graph showing the 3rd record.
