Antarctica sees record warm temps
March 7, 2017
There’s no time like the present for an update on the weather in Antarctica. Be aware, however, that there’s a significant time delay involved. According to the World Meteorological Organization, the world’s southernmost continent has set a new mark for its warmest temperature on record at 63.5 degrees. The new record was measured at Argentina’s Esperanza research station on Antarctica’s northern tip way back on March 4, 2015, but it’s taken this long to verify the reading.
For the record, the warmest temperature in the Antarctic region remains 67.6 degrees, set on Signy Island in January 1982. Our planet’s coldest temperature on record also occurred on Antarctica, in 1983, an impressive 128.6 degrees below zero in July, the dead of winter on that continent.
Meanwhile, the National Snow and Ice Data Center reports that Antarctica’s sea ice extent, apparently mimicking the recent behavior of the Arctic’s ice, dropped to a record low of 2,106,000 square kilometers this month. It should be noted that satellite records of Antarctic ice only date back to 1979. Oddly, annual Antarctic ice minimums were at record highs as recently as 2013-15, but several atmospheric factors have since shifted.
