In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.
磷可能阻止了全球变暖，它使本来长期得不到生长的森林生长，使本来受限制的树木吸收二氧化碳的能力通过生长得到了释放。
This may put a check on global warming by removing what would otherwise be a long-term constraint on the forest's ability to suck up carbon dioxide as it grows.
干木材重量的大约一半是由碳组成的，如果树腐化了，或被燃烧了，大部分碳都会以二氧化碳的形式释放出来。
Roughly half the dry weight of a tree is made up of stored carbon, most of which is released when the tree rots or is burned.
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。
Rising temperatures will melt the world's regions of permafrost, releasing more carbon dioxide and methane, which will raise temperatures even further.
协议还包括了12项有关碳吸收和储存的实验计划——运用新的技术来收集发电站释放的二氧化碳，并在地下将其燃烧。
The package also includes provision for 12 pilot projects on carbon capture and storage - using novel technology to collect CO2 emitted from power stations and bury it underground.
植物在其生长期内不断吸收大气中的二氧化碳，当燃烧这些植物以获取能量及／或热量的时候，它们会将二氧化碳释放出来。
The carbon dioxide released when burning them to produce power and/or heat was extracted by the plant from the atmosphere during its lifetime.
