The temperature at one research base in Antarctica reached a record-breaking 18.3 degrees Celsius (65 Fahrenheit) on Thursday, almost a full degree above the previous high set five years ago.  

Argentine scientists on the Esperanza base who confirmed the reading said that wasn’t the only record broken this week. The nation’s Marambio site registered the highest temperature for the month of February since 1971. Thermometers there hit 14.1 Celsius, above the previous February 2013 reading of 13.8 Celsius.
