"Methane is the second most important gas after carbon dioxide. It is responsible for a fifth of the enhanced greenhouse effect over the past 200 years," says Dr Paul Fraser, a chief research scientist at CSIRO Atmospheric Research. "Over the past four years there has been no growth in ...
The main greenhouse gas that causes climate change is ___. A. oxygen B. carbon dioxide C. nitrogen D. helium 相关知识点: 试题来源: 解析 B。解析:在气候变化因素中,二氧化碳(carbon dioxide)是主要的温室气体。氧气(oxygen)是人类呼吸所必需的气体,与气候变化关系不大;氮气(nitrogen)是大气中的主要成...
B。中文解析:文中提到“The burning of fossil fuels, such as coal, oil, and gas, is the largest source of greenhouse gas emissions.”,化石燃料的燃烧是温室气体排放的最大来源。A 选项森林砍伐会导致全球变暖,但不是最大的温室气体排放源;C 选项农业会产生温室气体,但不是最大的来源;D 选项废物处理也...
Which of the following is the largest source of greenhouse gas emissions? A. Deforestation. B. Industrial processes. C. Agricultural activities. D. The burning of fossil fuels. 相关知识点: 试题来源: 解析 D。中文解析:文中提到燃烧化石燃料,如煤炭、石油和天然气,是温室气体排放的最大来源。A ...
We definitely should think of water vapor as a feedback, even though it is themost important“greenhouse” gas. A very readable and good summary of some basics is found in this free paper: Water Vapor Feedback and Global Warming, I.M. Held & B.J. Soden, Annual Review of Energy and ...
___ 相关知识点: 试题来源: 解析 答: C 解: 由题干中Each greenhouse gas和distinctive ability定位至C段。本段讲到每一种温室气体在吸收空气中热量方面的能力都不相同(differs in its ability to absorb heat in the atmosphere),故匹配段落为C段。反馈 收藏 ...
【题目】What is the single most effective way toreduce greenhouse-gas emissions? Go vegetarian? Replant the Amazon? Cycle to work?None of the above. The answer is: make air-conditioners radically better. On one calculation, replacing refrigerants(制冷剂) that damage the atmosphere would reduce ...
Those three sources account for at least 19 percent each of food’s contribution to a warming planet, according to the study, with meat contributing the most, at 33 percent. All emit(散发)large amounts of methane(甲烷), a potent(强有力的)greenhouse gas with more than 80 times the ...
Which gas is most responsible for the enhanced greenhouse effect in recent years? A. Oxygen B. Nitrogen C. Carbon dioxide D. Argon 相关知识点: 试题来源: 解析 C。解析:近年来,二氧化碳(Carbon dioxide)对增强温室效应负有最大责任。二氧化碳在大气中的浓度不断增加,它能吸收地面辐射并阻止热量向太空...
1 C What is the single most effective way to reduce greenhouse-gas emissions?Go vegetarian? Replant the Amazon? Cycle to work? None of the above. The answer is: make air-conditioners (空调)much better. On one calculation, replacing refrigerants(制冷剂)that damage the atmosphere would reduce...
