Temperatures ın Antarctica Hit A Record High of 18.3 C ̊

Antarctica has experienced its highest temperature on record, according to meteorologists at the UN. 

The new record of 64.9°F (18.3°C) was set on February 6, 2020, a team at the UN agency the World Meteorological Organization (WMO) has revealed.

The reading was captured at the Esperanza Base, an Argentine research station on the Antarctic Peninsula – the northwest tip near to South America, and among the fastest warming regions on Earth.

WMO scientists blamed global warming and said the reading is another reminder that ‘climate change requires urgent measures’.

Greenhouse gas emissions from human activities, such as burning coal for power, cause the rise in global temperatures, leading to a potentially catastrophic rise in sea levels.

‘It is essential to continue strengthening the observing, forecasting and early warning systems to respond to the extreme events that take place more and more often due to global warming,’ said Professor Celeste Saulo, first vice president of WMO.

Antarctica spans more than 5 million square miles (14 million km2), making it roughly twice the size of Australia.

The average annual temperature ranges from about -10°C on the Antarctic coast to -60°C at the highest parts of the interior continent.

Its immense ice sheet is up to 3 miles (4.8km) thick and contains 90 per cent of the world’s fresh water, enough to raise sea level by just under 200 feet (around 60 metres) were it all to melt from global warming.

The previous record for Antarctic land (Antarctica), including mainland and surrounding islands, was 17.5°C (63.5°F) recorded on March, 24 2015 at Esperanza.

But the record for the whole of the Antarctic region – all ice and land that’s south of 60 degrees latitude – is 67.6°F (19.8°C), taken on Signy Island in January 1982.

According to the WMO, the Antarctic Peninsula is among the fastest warming regions of the planet, and has warmed by almost 5.4°F (3°C) over the last 50 years.

‘This new temperature record is therefore consistent with the climate change we are observing,’ said WMO Secretary-General Professor Petteri Taalas.

‘Verification of the maximum temperature record is important because it helps us to build up a picture of the weather and climate in one of Earth’s final frontiers.

‘Even more so than the Arctic, the Antarctic, is poorly covered in terms of continuous and sustained weather and climate observations and forecasts, even though both play an important role in driving climate and ocean patterns and in sea level rise.’

Researchers say a large high-pressure system over the area created what’s known as ‘föhn’ conditions – downslope winds producing surface warming – resulting in local warming at Esperanza.

The new record will now be added to the WMO Archive of Weather and Climate Extremes, which includes the world’s highest and lowest temperatures, as well as data on rainfall, heaviest hailstone, longest dry period and maximum gust of wind.

The assessment is detailed further in a paper published by WMO scientists, published in Bulletin of the American Meteorological Society.
