[:ja]NASAの地球観測衛星Landsat 8が撮影した南極、トリニティ半島のイースト島の融氷の様子です。
世界気象機関（WMO）によると、アルゼンチン気象局は、2020年2月6日に南極半島北端のアルゼンチン南極観測基地エスペランサで、2015年3月24日の17.5℃を上回る18.3℃を記録したと発表しました。これは隣接諸島を含む南極大陸における気温の観測史上最高記録となります。当局は、高温の要因としてフェーン現象をあげています。南極半島は地球上で温暖化の進行が最も速い地域の一つで、過去50年間に3℃以上気温が上昇しました。

[Earthview Wonders] No.1027: Ice Melting in Antarctica🇦🇶
NASA’s Landsat 8 satellite captured the ice melting at East Island, Antarctica.
On Feb. 6, 2020, Esperanza Base long Antarctica’s Trinity Peninsula recorded 18.3C, the hottest temperature on record for Antarctica, breaking the record of 18.3C on March 24, 2015. The warm spell caused widespread melting on nearby glaciers. The warm temperatures of Feb. 2020 were considered to be caused by a combination of meteorological elements. A ridge of high pressure was centered over Cape Horn at the beginning of the month, and it allowed warm temperatures to build.
The local scenery on the ground of Esperanza Base near East Island is as follows.
