1·An increasingly attractive theory holds that decreases in atmospheric carbon dioxide start the cooling trend that leads to glaciation.
一个越来越有吸引力的理论认为，大气中二氧化碳的减少引发降温趋势，这趋势导致冰川作用。
2·When our Sun later became hotter, the continued removal of atmospheric carbon dioxide and methane by early bacteria kept Earth's climate from becoming too hot to sustain life.
当我们的太阳后来温度变得更高时，早期细菌持续清除大气中的二氧化碳和甲烷，使地球的气候不至于变得太热而无法维持生命的存在。
3·While experiments subsequently confirmed that such a procedure increases phytoplankton growth, field tests have shown that such growth does not significantly lower atmospheric carbon dioxide.
虽然后来的实验证实，这种方法增加了浮游植物的生长，但实地试验表明，这种生长不会显著降低大气中的二氧化碳。
4·Instead, they know how to use sunlight to convert atmospheric carbon into oil in real time.
代之的是，他们可以利用阳光将大气中的碳实时转换成燃油。
5·Studies have shown that atmospheric carbon dioxide levels correlate with global temperature.
研究表明大气中的二氧化碳的含量与全球温度密切相关。
6·At the end of the last ice age, atmospheric carbon dioxide levels shot up by nearly 50 per cent.
在上个冰期末，二氧化碳含量增长了近50%。
7·In the scant century and a half since then, we've bumped atmospheric carbon dioxide up to 390 PPM.
在不到一个半世纪后，我们把大气中的二氧化碳猛增到百万分之390。
8·But these will not stabilise levels of atmospheric carbon dioxide - only slow the rate of increase.
但是这无法稳定大气中的二氧化碳水平——而只能降低增加的速率。
9·The research shows that atmospheric carbon dioxide levels are closely correlated with global temperatures.
研究表明大气中的二氧化碳的含量与全球温度密切相关。
10·Organic carbon is an important component of soil health and also influences atmospheric carbon dioxide levels.
有机碳是保持土壤健康的重要成分，同时也影响着大气中的二氧化碳浓度。
