The heat generated by burning a fossil fuel is surpassed within a few months by the warming caused by the release of its carbon dioxide into the atmosphere, according to new work from Carnegie's Xiaochun Zhang and Ken Caldeira published in Geophysical Research Letters, a journal of the American...
Scientists monitor carbon dioxide in the atmosphere by pumping air into an artificial chamberand shining an infrared light through the sample. Carbon dioxide absorbs infrared light very efficiently — more on that in a minute — so the amount of infrared absorbed can be used to calculate the ...

4.3. U6 Methane is oxidized to carbon dioxide and water in the atmosphere. 甲烷的形成 甲烷是天然气的成分之一,由一种特殊的无氧呼吸方式产生(methanogenesis),某些细菌利用有机酸(organic acid),酒精(alcohol)产生了乙酸(acetate),二氧化碳和氢,这些产物会被产甲烷古生菌(methanogenic archaeans)通过两种方式利用...
MethanationP-GraphReaction pathwaysHydrogenCarbon dioxideThe effects of carbon dioxide in the atmosphere can be reduced by closing anthropogenic cycles, and the methanation of carbon dioxide with hydrogen provides a promising option. Nevertheless, the react...
(1)细节理解题。根据文章第一段The atmospheric level of carbon dioxide(CO2)-a gas that is great at trapping heat,contributing to climate change is almost double what it was prior to the Industrial Revolution.(大气中二氧化碳(CO2)-一种非常善于吸热的
Transition-metal-catalyzed C–C bond formation through the fixation of carbon dioxide Carbon dioxide is an important carbon source in the atmosphere and is "problematic" toward the activities of human beings. Although carbon dioxide is a che... K Huang,Sun, Chang-Liang,Shi, Zhang-Jie - 《Che...
The exchange of CO2 between inner estuaries and the atmosphere has been recently evaluated using data from 106 systems6. The estimated global emissions of 0.26 Pg C year21 from these systems is lower than previous estimates, which have been in the range of 0.27 to 0.60 Pg C year211,2,7–...
must be removed from the atmosphere and stored. Plants and trees do this naturally.But there's so muchCO2 in the atmosphere that planting trees and protecting forests won't come close to solving the problem.That means humans need to come up with ways of removing carbon ...
