South Pole’s warmest August: Wunderground’s weather historian Christopher Burt reports: “This past August was the warmest such on record at the South Pole’s Amundsen-Scott Station. The temperature averaged -53.3°C (-63.9°F) breaking the previous record of -53.5°C (-64.3°F) set in August 1996. The departure from normal was +6.3°C (+11.3°F).”  Records extend back to 1958 at that Antarctic weather station.
