阿根廷观测数据显示，南极半岛6月初已出现15.4摄氏度的异常气温，比正常水平高出20多摄氏度，创下历史同期新高，冰层也出现异常融化。

阿根廷埃斯佩兰萨南极科考站的6日观测数据显示，南极半岛当日气温达到15.4摄氏度，超过历史上6月的单日最高气温纪录，即1998年录得的13.3摄氏度。

Antarctic experienced an extraordinary heat anomaly this month, with the temperature hitting 15.4 degree Celsius on June 6, shattering the region's previous winter record and raising concerns about the rapid ice melt.

The early June reading, taken on the Trinity Peninsula by the Argentine research station Esperanza Base, surpassing the station's previous June record of 13.3 degrees Celsius set in 1998, and also far exceeding its June average of minus 6.2 degrees Celsius.

阿根廷国家气象局专家何塞·路易斯·斯特拉11日在接受采访时表示，虽然今年6月初距南极半岛较近的阿根廷各地气温普遍偏高，但南极半岛的气温“比正常水平高出20多摄氏度，这是不寻常的现象”。

据阿根廷方面消息，历史记录中埃斯佩兰萨南极科考站6月的平均最高气温为零下6.2摄氏度。此外，6月5日至6日，阿根廷马兰比奥南极科考站和圣马丁南极科考站的最高气温分别达到11.8摄氏度和9.4摄氏度，而这两个科考站6月的平均最高气温分别为零下10.7摄氏度和零下5.6摄氏度。

科研人员说，由于过去三周每日最高气温都在零摄氏度以上，埃斯佩兰萨南极科考站所在区域至今没有积雪，这会对极地生态系统产生不利影响。

Record heat was also observed at other Argentine Antarctic stations between June 5 and June 6. Marambio Base reached 11.8 degrees Celsius, far above its June average of -10.7 degrees Celsius and its previous record of 9.2 degrees Celsius, while San Martin Base recorded 9.4 degrees Celsius, compared with its June average of -5.6 degrees Celsius and its previous record of 7.8 degrees Celsius.

Chilean glaciologist Luis Munoz told The Guardian that it was "very strange," adding that the area would normally still be covered in around 20 centimeters of snow and a lot of ice on the ground at this time of year.
