Antarctica’s highest temperatures on record

Thursday, 2 March 2017

PARIS: The UN’s World Meteorological Organization published the highest temperatures on record in 3 Antarctic zones Wednesday, setting a benchmark for studying how climate change is affecting this crucial region.

Mapping Antarctica’s extremes is essential for understanding weather patterns, and teasing out natural climate variability from human-induced climate change, the WMO said in a statement.

“Verification of maximum and minimum temperatures help us to build up a picture of the weather and climate in one of Earth’s final frontiers,” Michael Sparrow, a polar expert with the WMO-affiliated World Climate Research Programme, said in a statement.

For the entire Antarctic region, the highest temperature recorded was 19.8°C (67.6°F), on 30 January 1982, at a research station on Signy Island.

For the continent itself, a maximum of 17.5°C (63.5°F) was recorded on 24 March 2015, near the northern tip of the Antarctic Peninsula.

Finally, the highest temperature for the Antarctic Plateau — at or above 2,500 metres (8,202 feet) was minus 7°C (19.4°F), on 28 December 1980, at a weather station.

Getting a better grip on how global warming might impact the world’s largest ice mass is of more than academic interest.

Spanning an area twice the size of Australia, Antarctica’s ice sheet — up to 4.8 kilometres (3 miles) thick — contains 90% of the world’s fresh water, enough to raise sea levels by about 60 metres were it to melt.

The continent’s western peninsula, close to the tip of South America, is already among the fastest warming regions on the planet, hotting up by 3°C (5.4°F) over the last half century — three times the global average.

The lowest temperature yet recorded by ground measurements for the Antarctic Region — and the whole world — was minus 89.2°C (minus 128.6°F) at Vostok station on 21 July 1983.
