Carbon dioxide in the atmosphere helps to trap heat, which causes earth's temperatures to rise.
例如平均气温的上升，它会使长期冰藏在冰层里的二氧化碳和甲烷从永冻层里释放出来——相当于温室气体二氧化碳的20倍密度。
Rising average temperatures, for example, threaten to unlock long-frozen stores of carbon dioxide and methane -- at least 20 times as potent a greenhouse gas as CO2 -- from the region's permafrost.
你的生活方式决定了你每天排放出的二氧化碳数量，而二氧化碳的排放导致了温室气体的上升，并引起全球变暖。
Your lifestyle determines the amount of carbon dioxide emitted on a daily basis, which in turn contributes to the greenhouse gases that are causing global warming.
自从1997年条约签署以来，全球二氧化碳排放量已经上升了20%，计划明显没有那么奏效。
