How Antarctica hit record heatwave in Europe, Arctic- Technology News, Firstpost


If you’ve been following international weather news in June, you’re probably still trying to handle some amazing reports record heat wave in some of the coldest places on the planet.

From Canada to Russia, temperatures have risen with the threat posed by flora and fauna, which has caused concern among experts and the general public. And now there is news that Antartica has also registered a new record. If you’re wondering what’s going on, read on.

When was the highest value in Antarctica recorded?

The UN body, the World Meteorological Organization (WMO), announced on July 1 that new record as the maximum temperature on the southernmost continent is now 18.3 degrees, which masked the previous maximum temperature of 17.5 degrees in March 2015.

The reading revealing the latest altitude was taken in February 2020 at the same ice station called Esperanza, operated by Argentina, where the previous highest value was recorded.

Interestingly or perhaps worryingly, you could say that Antarctica had an even higher reading – 20.75 degrees, which was again recorded by the Brazilian station in February 2020 – which the WMO inspection team actually fired due to measurement problems with the device.

It must be borne in mind that the new record is only for the continent of Antarctica. The highest level of mercury has ever been in the larger Antarctic region, which includes Antarctica and any ice or land areas south of 60 degrees latitude, is 19.8 degrees, recorded in January 1982.

Why it is a concern

2020 was the hottest record in the world since 2016, and the decade of 2010 was now classified as the hottest decade since scientists began measuring the weather. According to experts, the rise in temperatures is undoubtedly due to man-made climate change.

The Antarctic region has been called one of the “last frontiers of the planet,” and with its Arctic region is considered “an important role in controlling the climate and the oceans and sea level rise.”

According to experts, the Antarctic Peninsula, which is the northernmost tip of the continent, mainly South America, “is one of the fastest warming regions on the planet, almost three degrees in the last 50 years.”

“This new temperature record is therefore in line with the climate change we have observed,” said Professor Petteri Taalas, Secretary General of WMO.

According to the WMO, the Antarctic continent is roughly double that of Australia and covers a total of 14 million square kilometers.

In cold, windy and dry climates, Antarctica sees average annual temperatures ranging from -10 degrees Celsius to -60 degrees on the coast in the highest parts of the continent.

WMO adds that its “huge ice sheet is up to 4.8 km thick and contains 90 percent of the world’s fresh water, enough to raise the sea level by about 60 meters if everything melts.”

What caused the disc to be read?

A particular factor that raised temperatures in Antarctica was, according to the WMO, a large high-pressure system that created “downhill winds that produce significant surface warming,” conditions that it added “contributed to the production of record temperature scenarios.”

However, for the root cause, there is no need to look beyond climate change. “This new record shows once again that climate change requires urgent action. It is essential to continue to strengthen detection, forecasting and early warning systems to respond to the extreme events that are increasingly occurring due to global warming,” said Professor Celeste, Argentine expert and first vice-president of WMO. Saulo.

Referring to the Northern Hemisphere heat wave, whose records are broken in Russia, Eastern Europe, the United States and Canada, WMO said “heat is more typical of West Asian summer temperatures” than areas with glaciers, meaning “resulting in a high risk of glacier melting.”

Climate change poses risks to “health, livelihoods, food security, water supply, human security and economic growth”, which may be exacerbated by a 1.5 degree global warming from pre-industrial levels. Limiting warming to 1.5 degrees Celsius instead of 2 degrees Celsius “could lead to 420 million people being less exposed to intense heat waves,” the Intergovernmental Panel on Climate Change has stated.
