人类活动正在以前所未有的速度改变北极环境,导致北冰洋迅速变暖、变冷、海冰退缩和海洋酸化。一氧化二氮(N2O)和甲烷(CH4)等微量气体在北极的大气反应性和辐射收支中都起着重要作用,因此具有影响该地区气候的巨大潜力。然而,对于这些快速的物理和化学变化将如何影响来自北冰洋的主要与气候有关的微量气体的排放,人们知之甚少。这些压力源的综合后果呈现出复杂的环境变化组合,这些变化可能影响微量气体的生产及其随后向北极大气的释放。在这里,我们介绍了我们目前对北冰洋一氧化二氮和甲烷循环的理解及其与区域和全球大气和气候的相关性,并提出了我们对未来几十年这种情况可能如何变化的看法。在线版本包含补充材料,下载地址为10.1007/s13280-021-01633-8。
Human activities are changing the Arctic environment at an unprecedented rate resulting in rapid warming, freshening, sea ice retreat and ocean acidification of the Arctic Ocean. Trace gases such as nitrous oxide (N2O) and methane (CH4) play important roles in both the atmospheric reactivity and radiative budget of the Arctic and thus have a high potential to influence the region’s climate. However, little is known about how these rapid physical and chemical changes will impact the emissions of major climate-relevant trace gases from the Arctic Ocean. The combined consequences of these stressors present a complex combination of environmental changes which might impact on trace gas production and their subsequent release to the Arctic atmosphere. Here we present our current understanding of nitrous oxide and methane cycling in the Arctic Ocean and its relevance for regional and global atmosphere and climate and offer our thoughts on how this might change over coming decades.
