    法媒稱南極海冰迅速融化:海冰消失面積相當于4個法國

    2019-07-03 06:35:01 參考消息網

    參考消息網7月3日報道 法媒稱,根據7月1日發表的一份研究報告,經過數十年的神秘擴張,南極海冰在短短幾年內融化的面積相當于法國國土面積的4倍,目前南極海冰的覆蓋面積處于歷史最低水平。

    據法新社7月1日報道,科學家已經知道,由于冰川(即緩慢向海岸推進的冰河)加速融化,南極像北極一樣正在加速消融。

    報道稱,從1979年至2014年,科學家觀察到一種既有趣又令人安心的現象:南極海冰的覆蓋范圍不斷擴大。

    但美國航空航天局的氣候學家克萊爾·帕金森說,從2014年至2017年,“南極海冰融化的面積幾乎相當于近40年來北極海冰融化的面積,而且這種趨勢仍在持續。”

    報道稱,南極海冰覆蓋面積的峰值曾達到1280萬平方公里,但現在已縮小200萬平方公里,原因尚不清楚。

    帕金森說:“它已從2014年的40年來最高點降至2017年的40年來最低點。”帕金森的研究報告發表在美國《國家科學院學報》月刊上。

    報道稱,研究小組分析了美國航空航天局和軍用衛星在這一時期的微波測量數據,并繪制出迄今為止有關這一歷史時期海冰覆蓋面積最精確的圖像,他們只衡量海冰的面積而不考慮其厚度。

    科學家尚不十分清楚,南極海冰以前擴張和現在縮小的原因。

    報道稱,關于這些變化的原因,有各種各樣相互矛盾的假設,有的認為是臭氧層空洞,有的認為是風向和洋流的變化,但這些假設都遠不夠明確。

    研究報告的同行評審之一、哥倫比亞大學海洋學家道格拉斯·馬丁森說:“在我看來,所有假設都不夠好。”

    但他告誡不要將北極研究發現應用到南極,他說,這樣做“就像將蘋果和軍用卡車作比較”。

    北極是被陸地包圍的海洋,而南極是被海洋包圍的大陸,那里冰山受到的限制較小。

    報道稱,與北極不同,南極并未變暖,仍然是地球上最冷的地方,也是最大的淡水來源。

    根據2013年的一項研究,覆蓋南極山脈的冰能夠讓海平面升高57米。

    倫敦大學學院的氣候學家克里斯·拉普利說,以前南極海冰面積擴大的事實無論如何都不會削弱全球變暖的論點。

    拉普利說:“這僅僅說明,在一個復雜的、相互關聯的系統中,可能出現與直覺相反的結果——至少在一段時間內是這樣。”

    他說:“我們傾向于對因果關系作簡單化的解釋,而實際上情況要復雜微妙得多。”(編譯/劉白云)
