摘要

Earth's climate is wanning as a result of anthropogenic emissions of greenhouse gases, particularly carbon dioxide (CO_2) from fossil fuel combustion. Anthropogenic emissions of non-CO_2 greenhouse gases, such as methane, nitrous oxide and ozone-depleting substances (largely from sources other than fossil fuels), also contribute significantly to warming. Some non-CO_2 greenhouse gases have much shorter lifetimes than CO_2, so reducing their emissions offers an additional opportunity to lessen future climate change. Although it is clear that sustainabty reducing the warming influence of greenhouse gases will be possible only with substantial cuts in emissions of CO_2, reducing non-CO_2 greenhouse gas emissions would be a relatively quick way of contributing to this goal.%Non—CO_2 greenhouse gases and climate changern人类活动产生的CO_2排放对气候的影响已被广rn泛认识到，但除了C_2外还有大量温室气体，rn它们受到的关注要少得多。在这篇Review文章rn中，Stephen Montzka和其他作者总结了我们rn当前关于包括甲烷、一氧化二氮和氯氟烃等卤rn化物在内的非CO2温室气体的知识。虽然这些rn气体的总变暖效应要低于CO_2的变暖效应，但rn它们排放量的实质性减少也将会显著降低人类rn活动对我们气候的影响。而且，因为非CO_2温rn室气体在大气层中的寿命往往短于CO_2，所以rn气候系统对前者减排的反应将会快于对只减排rnCO2的反应。
