As we said, these hydrothermal vents are releasing into the ocean depth this intensely hot water that contains a chemical called hydrogen sulfide, and also a gas, carbon dioxide.

正如我们所说，这些热液喷口正在向海洋深处释放这种强热的水，含有一种叫做硫化氢的化学物质，和一种气体，二氧化碳。

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。
