Rising temperatures will melt the world's regions of permafrost, releasing more carbon dioxide and methane, which will raise temperatures even further.
温度上升将融化世界范围内的冻土层，释放更多的二氧化碳和甲烷，这将导致温度的进一步升高。
The emission of methane and nitrous oxide is largely the result of agricultural activities; nitrous oxide from fertilisers and methane mostly from cows.
