For example, during the last ice age, he said, what was happening in the oceans dramatically affected levels of atmospheric carbon dioxide, or CO2.
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。
Rising temperatures make carbon dioxide leak from the oceans for two main reasons. First, melting sea ice increases the rate that the ocean mixes, which dredges up CO2-rich deep ocean waters.
二氧化碳从海洋中泄露出来，原因有两点，一是冰层融化，导致海洋气体溶解速率增长。
His group is not the first to use such data (ice cores, fossils, Marine sediments and the like) to probe the climate's sensitivity to carbon dioxide.
他的团队不是第一个使用这样数据探究气候对二氧化碳的敏感性的。
Owing to fossil-fuel emissions, there is now one-third more carbon dioxide in the atmosphere than at any time in at least a million years, as the latest ice drilling in Antarctica has revealed.
正如最近南极冰层钻探透露的消息，由于化石燃料的排放，如今大气中的二氧化碳含量比至少一百万年内的任何时候都多了三分之一。
Human-caused increases in atmospheric methane, which oxidizes into carbon dioxide and water vapor, could be providing more water for ice in the stratosphere.
人为增加大气中的甲烷，其氧化为二氧化碳和水汽后，能为平流层的冰提供更多的水份。
Much of the cooling during the ice ages was maintained by the presence of a large northern hemisphere ice cap reflecting away a lot of sunlight, but carbon dioxide levels were lower, too.
在冰河时期里，之所以有很多的气候冷却现象，是由于覆盖在北半球上的巨大冰盖将大量的阳光反射到外太空。但是，那时大气中的二氧化碳浓度也要低得多。
Carbon dioxide, in his view, is the main culprit. Black carbon deposited on the Arctic snow and ice, he says, will have only a minimal effect on its reflectivity.
他认为二氧化碳是主要的“凶手”，而北冰洋雪和冰上聚集的黑碳对反射作用的影响很小。
How come a big ice age happened when carbon dioxide levels were high?
在大冰河期，二氧化碳含量水平怎么会高呢？
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%。
Crutzen has suggested that the Anthropocene began in the late 18th century, when, ice cores show, carbon dioxide levels began what has since proved to be an uninterrupted rise.
Crutzen建议人类世在18世纪晚些时候开始，期间在冰核里自从CO2存在时可以显现二氧化碳不停地增长。
Previous estimates used cores from regions with low snowfall, van Ommen says, leading to a very gradual trapping of the carbon dioxide in the ice.
早期的估计是通过雪崩地区的核心来完成的，vanOmmen认为二氧化碳气体可能融入到冰层中去。
This article primarily discusses applications of carbon dioxide, dry ice and synthesis of chemical products, carbon dioxide supercritical carbon dioxide extraction technology.
主要论述了二氧化碳、干冰、二氧化碳合成化工产品以及二氧化碳的超临界萃取技术等方面的应用。
Additional equipment carried over could also produce fertilizer, methane and oxygen using the atmosphere's natural elements of nitrogen, carbon dioxide and its surface of ice water.
带去的其他设备还可以用火星大气中天然的氮气、二氧化碳和表面的冰水制造出肥料、甲烷和氧气。
These predict that if the level of carbon dioxide, methane and so on in the atmosphere continues to rise, then the Arctic Ocean will be free of floating summer ice by the end of the century.
他们预计，如果大气中二氧化碳，甲烷等气体比重继续上升，那么到本世纪末北冰洋的夏天将不再有浮冰。
The poles of Mars are capped with water ice and frozen carbon dioxide.
火星两极有上限的水冰和冰冻的二氧化碳。
On the other hand, the solid is NOT dry ice (carbon dioxide solid).
另一方面，该固体不是干冰(二氧化碳固体)。
The line is mainly used for washing, filling sealing carbon dioxide drink such as carbon dioxide water, cola, ice ter , aerated mineral water and so on.
该生产线主要用于含汽饮料，如汽水、可乐、冰茶、加汽矿泉水等饮料的冲洗、灌装、封口。
The Arctic ice cap will melt completely within the next century if carbon dioxide emissions continue to heat the Earth's atmosphere at current rates, according to an international study.
根据一项国际研究，如果二氧化碳继续不断排放，使得地球空气不断生温。到下个世纪，北极的冰盖将会完全的融化。
