alkane

alkane  

Saturated hydrocarbons with the general formula CnH2n+2. In systematic chemical nomenclature alkane names end in the suffix -ane. They form a homologous series (the alkane series) methane (CH4), ...
Animal Husbandry

Animal Husbandry  

Reference type:
Overview Page
Subject:
History
Concerned not only with ‘domestic animals,’ but also bees and silkworms. Throughout the MA, animals for the most part were allowed to wander free; thus horses, for example, were often ...
animal waste methane recovery

animal waste methane recovery  

The capture and reuse of methane produced from the decomposition of animal waste, before the manure or fertilizer is spread on fields. Recovery technologies include the anaerobic digester, and ...
Annex A Gases

Annex A Gases  

The greenhouse gases whose emissions are regulated by the Kyoto Protocol (as defined in Annex A) in order to reduce global warming and slow down climate change. The gases are carbon dioxide, methane, ...
atmosphere

atmosphere  

A gaseous envelope gravitationally bound to a celestial body; in the case of the Earth, with an average composition, by volume, of 79% nitrogen, 20% oxygen, 0.03% carbon dioxide, and traces of rare ...
atmospheric chemistry

atmospheric chemistry  

The study of the chemical composition of the atmosphere, of aerosols, pollutants, and rainfall, and the various chemical reactions in which they are involved. It includes the processes of ...
atmospheric structure

atmospheric structure  

The broadly horizontal layering of the atmosphere, the layers being distinguished by differences in the rate of change of temperature with height, which either favour or discourage the development of ...
biogas

biogas  

Reference type:
Overview Page
A mixture of methane and carbon dioxide that is generated by the anaerobic fermentation of organic matter such as plant residues and animal manure, and can be used as a renewable fuel or a fertilizer.
carbon cycle

carbon cycle  

The movement of carbon through the surface, interior, and atmosphere of the Earth. Carbon exists in atmospheric gases, in dissolved ions in the hydrosphere, and in solids as a major component of ...
Climate Reconstruction

Climate Reconstruction  

Our knowledge of climate history prior to the availability of instrumental records comes from two main sources: (1) historical observations, where information on past climatic conditions is contained ...
coal gasification

coal gasification  

The conversion, by heating and partial combustion, of coal into gases such as methane and carbon monoxide. It is an efficient fuel that produces less air pollution than burning unmodified coal. Coal ...
energy recovery

energy recovery  

The process of extracting useful energy from waste, such as the heat produced by incineration or by harnessing methane gas from landfills.
firedamp

firedamp  

Reference type:
Overview Page
n. (in mining) an explosive mixture of gases, usually containing a high proportion of methane, occasionally encountered in pockets underground. It can be distinguished from blackdamp (chokedamp), ...
flare

flare  

1 A sudden burst of flame.2 A device that burns gases (such as methane gas in a landfill) to prevent them from being released into the environment.
fossil fuel

fossil fuel  

All deposits of organic material capable of being burnt for fuel; chiefly coal, oil, and gas. These are formed under pressure by alteration or decomposition of plant or animal remains.
fuel cell

fuel cell  

A mechanical device that uses hydrogen or hydrogen‐based fuel (such as methane) to produce an electric current. Fuel cells are clean, quiet, and very efficient sources of electricity.
global warming

global warming  

The gradual increase in the overall temperature of the earth's atmosphere due to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.
global warming potential

global warming potential  

(GWP)A measure of the potential contribution of a gas to global warming. It is defined as the radiative forcing produced by the release of 1kg of the substance over its lifetime, relative to the ...
greenhouse effect

greenhouse effect  

Reference type:
Overview Page
The trapping of the sun's warmth in a planet's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the ...
greenhouse gas

greenhouse gas  

A gas composed of molecules that absorb and reradiate infrared electromagnetic radiation. When present in the atmosphere, therefore, the gas contributes to the greenhouse effect. On Earth, the ...
