我们知道，这样的板块活动对生命形成来说必不可少，它不仅有助于产生复杂化学过程，而且促使物质循环，比如释放二氧化碳进入大气层，使得地球保持温暖。
Such activity is essential to life as we know it, because it helps enable complex chemistry and recycles substances like carbon dioxide into the atmosphere, which keeps Earth warm.
比如，煤电厂，如果继续把煤电作为能源来源之一，我们就要捕捉并存储其排放的二氧化碳，这一过程称作“碳捕捉和隔离”(carboncaptureand sequestration)或缩写CCS。
For example, coal plants, if they are to remain a major part of the energy mix, will need to capture and store their CO2, a process called "carbon capture and sequestration," or CCS for short.

如今，大部分人造的二氧化碳排放体都已知晓，其排放量也已被测量，比如说大型的发电站。
Today, most big man-made carbon-dioxide emitters, such as a large power station, are known about and their outputs are measured.
也许有其他的方式来提高二氧化碳排放的价格，比如说在欧盟范围内提高二氧化碳税，这也会以某种方式影响进口。
There may be other ways to raise carbon costs that have more appeal: a rising EU-wide carbon tax, for example, that would be imposed in some form on imports too.
然而，如果将范围再扩大，那么骑车消耗的能量产生的二氧化碳就会在世界的其他角落以某种方式向大气排放，比如空运来的芦笋。
At the ridiculous high end of the scale, however, is getting your cycling calories by piling up your plate with asparagus that has been flown by air from the other side of the world.
参加会议的人会把发言人的讲话发到Twitter上比如比尔·盖茨的：“我对未来五十年只有一个愿望，就是发明一样东西可以让二氧化碳排放减少一半。

比如说，上个冰河时期地球海洋发生的一系列变化对大气中二氧化碳的含量产生了及其重大的影响。
For example, during the last ice age, he said, what was happening in the oceans dramatically affected levels of atmospheric carbon dioxide, or CO2.
默克尔相信，只有我们为每一位地球公民设定二氧化碳排放限额——比如说每人两吨——我们才能最有效的抑制全球变暖。
Merkel insisted that only by establishing limits on carbon dioxide output per individual around the world — suggesting about 2 tons per head — could the fight to stop global warming be effective.
