Both primary energy consumption and carbon dioxide emissions in the world increased continuously showing the same trends because nearly 90% of primary energy consumption was fossil fuel combustion. Only the economic depression of the world led to suppression of increases in primary energy consumption ...
Biomass carbon is what we might call current carbon. It's always going in and out of the atmosphere. So if we burn one of these fuels, we're putting its carbon into atmosphere. Right? But in a balanced system, somewhere else in the world the same amount of carbon is going back. It...
If current trends continue, by the year 2010 carbon emissions in the United Stateswill soar to a level more than one-third higher than were thosein 1990, according to official projections. 选项: A、will soar to a level more than one-third higher than were those ...
Well, biomass carbon is what we might call current carbon—Iit's always going in and out of the atmosphere.So if we burn one of these fuels, we’re putting its carbon into the atmosphere, right?But in a balanced system, somewhere else in the world this same amount of carbon is going...
Fossil fuels will remain the dominant source of energy well into the 21st century. Carbon sequestration is a potential solution for limiting the atmospheric release of carbon dioxide emissions that may contribute to global warming. If successful, carbon sequestration would enable the continued use of ...
(1)What can be inferred from the underlined sentence in paragraph one? AA.Airline's current efforts to reduce carbon emissions are far from enough.B.Airline companies haven't invested enough in their technological development.C.Only by promoting electric planes can airlines balance...
Human activity and climate change threatens the stability of this large pool, which has been decreasing rapidly over the last few decades owing to deforestation, drainage and fire. In this paper we estimate the carbon dioxide (CO(2)) emissions resulting from drainage of lowland tropical peatland ...
摘要: The report provides findings of the research on carbon sequestration and emissions in forest ecosystems of Kazakhstan. Based on different scenarios, the projections of carbon sinks are made by 203 and beyond.DOI: 10.13140/RG.2.1.2081.1762 年份: 2016 ...
Current status and future prospects for carbon forestry in Australia Carbon forestry is part of a suite of land-based activities that can be used to mitigate carbon emissions, and also provide a range of other environmental ... Mitchell,CD,Harper,... - 《Australian Forestry》 被引量: 21发表...
In order to reduce atmospheric emissions, the IEA recommends avoiding traditional fuels, improving energy efficiency and energy conservation, transitioning towards renewable energy sources, and developing low-carbon and carbon-capture technologies [8]. It is estimated that renewable energy can cover 10% ...
