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 10°F on Friday. In contrast, high temperatures at the station this time in March average below -50°F.
