Antarctica recorded the hottest temperature of 20.75 degrees Celsius

The World Meteorological Organization announced that for the first time in record Antarctica has recorded its hottest temperature ever, 20.75 Degree Celsius. So far, the highest was 18.3 Degrees Celsius that was recorded in January 1982.

Highlights

The higher temperatures were influenced by shifts in El Nino and Ocean Currents. According to United Nations scientists, the Antarctic region stores more than 70% of world’s fresh water. If it melts, the sea level will increase by 50 to 60 metres.

Significance of Ice Sheet in Antarctica

The ice sheet in Antarctica covers 14 million square kilometres. To the east of Antarctica there lies land masses under the ice sheets. However, on the west Antarctica the ice beds can extend to more than 2500 metres under the sea.

The Arctic and Antarctic Ice sheets are important as they reflect 80% to 90% of solar radiation. On the other hand, the other dark surfaced landforms reflect less solar radiation and retain great amount of heat.
