【题目】CWhat is the single most effective way to reduce greenhouse-gas emissions? Go vegetarian? Replant theAmazon? Cycle to work? None of the above. The answer is: make air-conditioners (空调)much better. On onecalculation, replacing refrigerants(制冷剂)that damage the atmosphere would ...
根据文章内容,尤其是第一段中The answer is make air-conditioners radically better.On one calculation, replacing refrigerants(制冷剂) that damage the atmosphere would reduce totalgreenhouse gases by the equivalent of 90bn tonnes of CO2 by 2050. Making the units more energy-efficient could double that...
CO2 is the most important greenhouse gas Of all the greenhouse gases emitted by humans, CO2 is the most important. More than half of the increased greenhouse effect is caused by CO2. Methane is in second place with 16%. Water vapor is also an important greenhouse gas, but humans do not ...
What is the gas that is mainly responsible for the greenhouse effect? A. Oxygen B. Nitrogen C. Carbon dioxide D. Hydrogen 相关知识点: 试题来源: 解析 C。本题考查温室效应的主要气体。二氧化碳是主要导致温室效应的气体。氧气(A 选项)和氮气(B 选项)不是温室效应的主要气体。氢气(D 选项)在大气中...
parts per million used to measure? A. Greenhouse gas emissions B. The concentration of greenhouse gases in the atmosphere C. A country's contribution to total greenhouse gas emissions D. The rate of deforestation 相关知识点: 试题来源: 解析 B 反馈 收藏 ...
A. It produces a lot of greenhouse gas emissions. B. It depends on sunlight and can't generate electricity all the time. C. It is too expensive to build solar panels. D. It is not sustainable. 相关知识点: 试题来源: 解析 B。 反馈...
is produced in wetland areas as the gas can only arise under anaerobic conditions, i.e. when there is no oxygen. Thawing permafrost, as a direct consequence of the rising global temperatures, thus represents a significant source of greenhouse gases in the form of methane emissions. The main ...
What is the most appropriate LCA method for measuring greenhouse gas emissions from bioenergy? Aylott, MJ, et al. Biofuels, Bioproducts and Biorefining, Vol. 5 (2), pp. 122-124.Aylott M, Higson A, Evans G et al (2011) What is the most appropriate LCA method for measuring greenhouse ...
