Accelerated Climate Changes in Weddell Sea Region of Antarctica Detected by Extreme Values Theory

On 13 February 2020, The Guardian, followed by many other newspapers and websites, published the news that on 9 Antarctic air temperatures rose to about 20.75 ?C in a base logged at Seymour Island. This value has not yet been validated WMO (World Meteorological Organization), but it is first time an extreme temperature was registered these locations. recorded have often described as “abnormal anomalous”, according statement made scientists working bases. Since polar regions shown most rapid rates of climate change recent years, this abnormality primary interest context vulnerability changes. Using data detected different bases, we investigate yearly maxima minima temperatures, order establish whether they can be considered usual events or abnormal. We found evidence for disagreement with values theory, indicating accelerated changes Antarctic, is, local warming rate much faster than global averages.
