新的研究发现格陵兰岛是一个甲烷汇，吸收的甲烷多于释放的甲烷，可能会减轻气候变化的影响。 New study finds Greenland as a methane sink, absorbing more methane than it releases, possibly lessening climate change impact.

哥本哈根大学的一项新研究表明，格陵兰岛吸收的甲烷多于其排放的甲烷，格陵兰岛无冰地区的干燥景观每年平均从大气中消耗 65,000 吨甲烷。 A new study from the University of Copenhagen reveals that Greenland absorbs more methane than it emits, with dry landscapes in the ice-free part of Greenland consuming an average of 65,000 tons of methane annually from the atmosphere. 这种吸收是由生活在北极土壤上层的一组独特的微生物实现的，它们将大气中的甲烷转化为二氧化碳，这是一种效力较低的温室气体。 This absorption is made possible by a unique group of microorganisms that live in the upper layers of arctic soil, which convert atmospheric methane into carbon dioxide, a less potent greenhouse gas. 尽管格陵兰岛的甲烷吸收量不足以影响全球大气甲烷总量，也不足以对北极甲烷预算产生决定性作用，但该研究的结果令人鼓舞，因为甲烷对环境特别有害。 Although Greenland's methane absorption is not large enough to impact the total global amount of atmospheric methane or prove decisive for Arctic methane budgets, the study's findings are encouraging as methane is particularly harmful to the environment.
