阿根廷觀測(cè)數(shù)據(jù)顯示，南極半島6月初已出現(xiàn)15.4攝氏度的異常氣溫，比正常水平高出20多攝氏度，創(chuàng)下歷史同期新高，冰層也出現(xiàn)異常融化。
阿根廷埃斯佩蘭薩南極科考站的6日觀測(cè)數(shù)據(jù)顯示，南極半島當(dāng)日氣溫達(dá)到15.4攝氏度，超過(guò)歷史上6月的單日最高氣溫紀(jì)錄，即1998年錄得的13.3攝氏度。
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.
阿根廷國(guó)家氣象局專家何塞·路易斯·斯特拉11日在接受采訪時(shí)表示，雖然今年6月初距南極半島較近的阿根廷各地氣溫普遍偏高，但南極半島的氣溫“比正常水平高出20多攝氏度，這是不尋常的現(xiàn)象”。
據(jù)阿根廷方面消息，歷史記錄中埃斯佩蘭薩南極科考站6月的平均最高氣溫為零下6.2攝氏度。此外，6月5日至6日，阿根廷馬蘭比奧南極科考站和圣馬丁南極科考站的最高氣溫分別達(dá)到11.8攝氏度和9.4攝氏度，而這兩個(gè)科考站6月的平均最高氣溫分別為零下10.7攝氏度和零下5.6攝氏度。
科研人員說(shuō)，由于過(guò)去三周每日最高氣溫都在零攝氏度以上，埃斯佩蘭薩南極科考站所在區(qū)域至今沒(méi)有積雪，這會(huì)對(duì)極地生態(tài)系統(tǒng)產(chǎn)生不利影響。
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.
