He added that such rapid melting is brought on by sustained excessive temperatures considerably above freezing. Such persistent heat was not typical in Antarctica till this century; nevertheless, it has developed into extra frequent; lately, NASA mentioned.
The temperature rose at 64.9 degrees Fahrenheit at Argentina’s Esperanza Base on Feb. 6, which was Antarctica’s warmest temperature on the report.
