海面以下有大量的甲烷,一种就可以含有所有陆地的化石燃料两倍的碳。比如说煤炭,石油和天然气,包括永远也不可能开采的那部分。甲烷是一种强有力的温室气体,是二氧化碳对温度升高效果的25倍。
There are massive amounts of undersea methane. One type alone may hold double the carbon of all of the terrestrial fossil fuel, such as coal, oil and natural gas, including stores that could never be recovered. Methane is a powerful greenhouse gas, contributing 25 times more toward warming than carbon dioxide, kilogram for kilogram over a century。
凯瑟勒表示,在地质学历史上水下的甲烷释放曾发生过,有时是喷发,有时是千万年地丝丝泄漏。并且气象学家已经表示一种大量的水下和甲烷结合的物质像冰一样的被称为可燃冰,会随着大洋的变暖而变得可能融化而泄漏。
Underwater methane releases have occurred in geologic history, sometimes as big burps of gas and sometimes as seeps lasting hundreds or thousands of years, Kessler said. Also, climate scientists have suggested that releases of vast stores of one type of water-associated methane -- an ice-like form called methane clathrate -- could happen as warming oceans allow some of these to melt。
尽管团队的发现表明甲烷吞噬微生物有潜在的吞噬大量泄漏的甲烷的可能。但是我们不可能把这条规律应用到整个世界。
