CLIMATE CHANGE: Antarctica Just Hit Its Hottest Temperature Ever Recorded

The hottest temperature ever recorded in Antarctica was measured on Thursday at a remote station on the continent's Northern tip, scientists said.

The temperature was nearly 65 degrees Fahrenheit (18.3 Celsius) at Argentina's Esperanza research station, scientists from the country's meteorological agency said.
That surpassed the previous record of 63.5 degrees Fahrenheit (17.5 Celsius) set on March 24, 2015, at the same location. Temperature records from Esperanza date back to 1961.

Argentina has been tracking temperatures from Esperanza since 1961, while records from Marambio date back to 1971.

The World Meteorological Organization (WMO) has not verified the record-breaking temperature, though the institution believes the new findings are accurate.

“Everything we have seen thus far indicates a likely legitimate record, but we will, of course, begin a formal evaluation of the record once we have full data from SMN and on the meteorological conditions surrounding the event,” WMO’s Randall Cerveny said in a release. “The record appears to be likely associated (in the short term) with what we call a regional ‘foehn’ event over the area: rapid warming of air coming down a slope/mountain.”

The Antarctic Peninsula — the northwest tip near South America where the two Argentinian bases are located — is among the fastest-warming areas in the world, rising almost 37.4 degrees Fahrenheit (20.78 degrees Celsius) over the last 50 years, according to the WMO.

The amount of ice lost annually from the Antarctic ice sheet has also increased at least six-fold between 1979 and 2017, the organization said.

Scientists determined 2019 was the second-hottest year on record in separate but similar reports by the National Oceanic Atmospheric Administration (NOAA)’s National Centers for Environmental Information (NCEI) and NASA released in January.
The records, which scientists began compiling in 1880, show that the last five years have been the planet’s warmest, with 2016 currently topping the list by just 0.07 of a degree Fahrenheit.

Studies have shown that many of Antarctica's massive glaciers are melting rapidly due to global warming. And all told, Antarctica's ice sheet contains enough water to raise global sea levels by nearly 200 feet, the WMO says.

A recent study found that warm ocean waters are melting the gigantic Thwaites Glacier in West Antarctica, which alone has the potential to raise global sea levels more than 10 feet.
And the neighboring Pine Island Glacier has also shown signs of increased instability in the last 25 years.
