Antarctica once had a temperature of 19.8ºC
The World Meteorological Organization revealed that the highest temperature recorded for the 'Antarctica Region', is 19.8ºC, observed in 1982. However, the lowest temperature recorded for the region, and for the whole world, was -89.2°C in 1983. The 4.8-km-thick Antarctic ice sheet contains enough water to raise the global sea level by around 60 metres if totally melted, said the report.
