If you’re following the June International Weather News, you’re probably still trying to process the next amazing report. Record-breaking heat wave In some of the coldest places on earth.
From Canada to Russia, temperatures are skyrocketing and the associated threat to flora and fauna raises concerns among professionals and the general public. And now there is news that Antarctica has also hit new highs. If you’re wondering what’s going on, read on.
When was the highest record in Antarctica?
The World Meteorological Organization (WMO), a United Nations agency, announced on July 1st: New record The highest temperature on the southernmost continent is currently 18.3 degrees Celsius, above the previous high of 17.5 degrees Celsius in March 2015.
The measurements that revealed the latest highs were taken in February 2020 at the same ice station, Esperanza, and were operated by Argentina, where the previous highs were recorded.
Interestingly, or perhaps surprisingly, Antarctica’s measurements were even higher, at 20.75 degrees Celsius, recorded at the Brazilian Observatory in February 2020. It was actually shot down by the WMO review team due to measurement issues. Terminal.
It should be noted that the new record is for Antarctica only. The highest mercury ever made in the larger Antarctic region, including all ice or land south of Antarctica and 60 degrees latitude, recorded in January 1982, is 19.8 degrees Celsius.
Why it causes anxiety
2020 was the hottest year in the world since 2016. The decade of the 2010s has been classified as the hottest decade since scientists began measuring the weather. Experts say that behind these rises in temperature is undoubtedly anthropogenic climate change.
The Antarctic region is called one of the “last frontiers of the Earth” and is considered with the Arctic to “promote climate and ocean patterns and play an important role in sea level rise.”
According to experts, the Antarctic Peninsula, at the northernmost tip of the continent closest to South America, is “one of the warmest regions on earth in the last 50 years, at about 3 degrees Celsius.”
“Therefore, this new temperature record is in line with the climate change we are observing,” said WMO Secretary-General Professor Petteri Taaras.
According to the WMO, Antarctica is about twice as large as Australia, spanning a total of 14 million square kilometers.
Antarctica is characterized by a cold, windy and dry climate, with average annual temperatures ranging from -10 degrees Celsius on the coast to -60 degrees Celsius in the highest part of the continent.
“The huge ice sheet is up to 4.8 km thick, contains 90% of the world’s freshwater, and if everything melts, it’s enough to raise sea level by about 60 meters,” WMO added.
What Causes Record Reads?
According to the WMO, the specific factor that raised the temperature in Antarctica was a large-scale high-pressure system that produced “downhill winds that caused significant surface warming,” and the additional condition was “record temperature. It helps to create scenarios. “
However, it may not be necessary to look beyond climate change for the root cause. “This new record once again shows that climate change requires urgent action. Observation, forecasting and early warning systems to respond to the increasingly frequent extreme events of global warming. It is imperative to continue to strengthen, “said Argentine experts. Professor Celeste Saulo, the first vice president of WMO.
The WMO referred to record-breaking heat waves in the Northern Hemisphere in Russia, Eastern Europe, the United States and Canada, saying it was “typical heat of summer temperatures in West Asia” rather than glacier areas. This means that there is a high risk of glaciers melting as a result.
Climate change poses risks to “health, livelihoods, food security, water supply, human security, economic growth” and can be exacerbated by global warming at 1.5 degrees Celsius above pre-industrial levels. The Intergovernmental Panel on Climate Change said limiting warming to 1.5 degrees Celsius instead of 2 degrees Celsius “may reduce the number of people exposed to severe heat waves by 420 million.”
