由美國和俄羅斯科學家組成的研究隊伍，剛於《自然》期刊發表文章，指出西伯利亞永久凍土層持續溶解，凍土層下的溫室氣體甲烷不斷釋放，較原先估計增加了5倍。
　　由於全球暖化，導致凍土層溶解，釋放甲烷；甲烷是溫室氣體之一，凍土釋放甲烷會令全球暖化問題加劇，形成惡性循環。事實上，自然界甲烷大量排放，影響可以是滅絕性的，地球上一次甲烷大量排放，可追溯到2億多年前，那一次導致地球物種大滅絕。
26年釋放增五成
　　研究隊伍於西伯利亞北部兩個溶解湖，量度從湖底冒出來的甲烷氣泡，計算它們的釋放量。由於該地區的溫度近年持續增升，由1974至2000年的26年間，兩個湖的甲烷釋放量已增加了58%。
　　西伯利亞凍土層上的湖泊，佔了九成是這種溶解湖，成為整片地區主要釋放甲烷的源頭。科學家估計，整片地區上的溶解湖和濕地，已釋放出超過400萬噸甲烷，數量較預期高出10％至63％不等。
　　
Research troop which are composed of American and the Russian scientists, just published the article inNature the periodical, pointed out that the Siberia permanent frozen soil layer dissolved continually, under the frozen soil layer's greenhouse gas methane released unceasingly, estimated originally increased 5 times. 　　As a result of the global warming, causes the frozen soil layer to dissolve, release methane; The methane is one of greenhouse gases, the frozen earth release methane will be intensified the global warming question, forms the vicious circle. In fact, the nature methane discharges massively, affects may be extinguishes the nature, the Earth previous methane discharges massively, may trace more than 200,000,000 years ago, that one time causes the Earth species to extinguish greatly. 26 year release increases 50% 　　The research troop in the Siberia northern two dissolution lake, measures the methane air bubble which braves from the lake bottom, calculates their release quantity. Because this area's temperature recent years continued to lift augmentation, from 1974 to during 26 years 2000, two lake's methane release quantities increased 58%. 　　On the Siberia frozen soil layer's lake, has accounted for 90% is this kind of dissolved lake, becomes the entire piece area main release methane the source. The scientist estimated that in the entire piece area's dissolved lake and the wetland, have released surpass 4,000,000 tons methane, quantity anticipated are higher than 10% different to 63%.
