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。
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。
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。
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。
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。
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。
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。
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)。
This article primarily discusses applications of carbon dioxide, dry ice and synthesis of chemical products, carbon dioxide supercritical carbon dioxide extraction technology.
