The last time it was 17.5 ° C, in March 2015. It was the highest temperature since records began. But that’s behind us. Now the record temperature in Antarctica is 18.3 ° C. This has been confirmed by the World Meteorological Organization (WMO).
The same station recorded the two temperatures. It is located at Foca Point in Esperanza Bay on the Trinidad Peninsula. In February 2020, a Brazilian station took a larger measurement on Seymour Island. It reached 20.75 ° C. The WMO did not confirm this, however, as a radiation protection shield changed the measurements.
Antarctica is one of the areas on the planet with the fastest rate of warming. The temperature in this region has risen by almost 3 ° C in the last 50 years. That says WMO General Secretary Petteri Taalas. “So this new temperature record is in line with the climate change we’re seeing,” he added.
The meteorological facility works with the Antarctic Treaty system. They are trying to keep this continent untouched, Taalas noted.
A WMO committee found that high pressure over the area creates characteristic wind conditions hairdryer (descending slope winds). These generate considerable surface heating. Ideal conditions to cause a rise in temperature. “It is important to check this record of the maximum temperature in Antarctica. It makes us aware of changes in the region, ”said Taalas.
In the Antarctic there is a lack of sufficient continuous and sustained meteorological observations. Like the Arctic, it affects weather and ocean patterns, as well as rising sea levels. “The fight against climate change requires urgent action,” said Celeste Saulo. He heads the National Weather Service of Argentina. And she is the First Vice President of the WMO.
It is essential to strengthen the monitoring, forecasting and early warning systems. This enables you to react more quickly to possible extreme events. A huge iceberg in May came off the Antarctic coast. Scientists attribute this phenomenon, observed in Antarctica over the past 30 years, to climate change.
