Greenhouse Gases (GHGs)
Greenhouse gases are components of the atmosphere that contribute to the greenhouse effect, which leads to climate change by warming global temperatures.
Greenhouse Gases
Greenhouse gases trap heat in the atmosphere, which makes the Earth warmer. People are adding several types of greenhouse gases to the atmosphere, and each gas's effect on climate change depends on three main factors: ...

The "greenhouse effect" often gets a bad rap because of its association with global warming, but the truth is we couldn't live without it.
Greenhouse Effect Greenhouse gases in the earth's atmosphere permit solar radiation to pass through but prevent most of the reflected infrared radiation from the earth's surface and lower atmosphere from escaping into outer space.
greenhouse effect - the process that raises the temperature of air in the lower atmosphere due to heat trapped by greenhouse gases, such as carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and ozone.
Greenhouse Effect. A general warming effect felt on Earth's surface, produced by greenhouse gases.
Greenhouse Effect
The normal process by which heat is kept in the atmosphere. Without it, life could not survive on Earth. But if too much heat is trapped, temperatures could go up. This would then be dangerous to life.
Greenhouse Gas Emissions Calculators
Calculators from EPA (but some non-EPA sites)-Greenhouse gas emissions calculators are available online from EPA and other organizations.
Greenhouse effect: The warming of the earth's atmosphere caused by a build-up of carbon dioxide or other trace gases; it is believed by many scientists that this build-up allows light from the sun' ...

Greenhouse effect: A warming of the Earth's atmosphere caused by the presence in the atmosphere of certain heat-trapping gases (e.g., water vapour, carbon dioxide, methane).
greenhouse effect: The greenhouse effect is when gases in the earth's atmosphere trap heat from the sun and build up, raising the temperature of the earth, acting like a greenhouse.
Greenhouse Gas Inventory: A greenhouse gas emissions inventory is an accounting of the amounts and sources of emissions of greenhouse gases attributable to the existence and operations of an institution.
Greenhouse gases
Gaseous constituents of the atmosphere, both natural and from human activity, that absorb and re-emit infrared radiation. Water vapor (H2O) is the most abundant 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 (heating of the earth's atmosphere).
Greenhouse effect - explains global warming. It's the process that raises the temperature of air in the lower atmosphere due to heat trapped by greenhouse gases, such as carbon dioxide, chlorofluorocarbons, and ozone.
Greenhouse Effect - The phenomenon in which outgoing infrared radiation that would normally exit from a planet's atmosphere but instead, ...
Greenhouse Effect (C):
Greenhouse effect refers to the trapping and build-up of heat in the atmosphere (troposphere) near the Earth’s surface.
Greenhouse Effect - The warming of earth's surface and lower atmosphere as a result of carbon dioxide and water vapor in the atmosphere, which absorb and reradiate infrared radiation.
Greenhouse Gas: A gas which contributes to the greenhouse effect. Common ones include carbon dioxide, methane and nitrous oxide. These gases occur naturally, but large amounts emitted by human activities are adding to the climate crisis.
Greenhouse effect
The warming of the Earth's atmosphere caused by increasing levels of gases, such as water vapour and carbon dioxide. These gases absorb radiation emitted naturally from the ground, so slowing down the loss of energy from Earth.
greenhouse effect: the effect of greenhouse gases in the atmosphere trapping a certain amount of the sun's heat as it reflects back off the surface of the earth towards space.
greenhouse effect The warming of the earth's surface resulting from the capacity of the atmosphere to transmit short-wave energy (visible and ultra-violet light) to the earth's surface and to absorb and retain heat radiating from the surface; ...
Greenhouse effect
The warming of the Earth's atmosphere attributed to a build-up of carbon dioxide or other gases; some scientists think that this build-up allows the sun's rays to heat the Earth, ...
greenhouse effect = longwave radiation emitted from the Earth's surface is absorbed by a greenhouse gas in the atmosphere; an important natural occurrence necessary for life on Earth ...
Greenhouse Effect: The warming effect of the Earth's atmosphere. Light energy from the sun which passes through the Earth's atmosphere is absorbed by the Earth's surface and re-radiated into the atmosphere as heat energy.
Greenhouse Effect is produced as greenhouse gases allow incoming solar radiation to pass through the Earth's atmosphere, but prevent most of the outgoing infra-red radiation from the surface and lower atmosphere from escaping into outer space.
G greenhouse gas
Definition (english only)
A gas that contributes to the natural greenhouse effect.
The greenhouse effect is thought to be potentially self-reinforcing in the Arctic.14 ...
Greenhouse effect
The effect of trapping heat by the transmission of visible solar energy, and the absorption (or reflection) of infra red heat energy. This can be done by a sheet of glass or a layer of some gases, known as greenhouse gases.

Greenhouse gases Gases which trap solar radiation. Of the solar energy entering the earth's atmosphere a portion is reflected back and a portion penetrates onto the earth's surface.
Greenhouse gases include carbon dioxide, methane, nitrous oxide, chlorofluorocarbons (CFC's) and water vapour. Carbon dioxide, methane and nitrous oxide have significant natural and human sources while only industries produce CFC's.
Greenhouse Effect
The trapping and build-up of heat in the lower atmosphere near a planet's surface.
Atmospheric Greenhouse Gas Concentrations
Atmospheric concentrations of greenhouse gases are usually expressed in parts per million (ppm) or parts per billion (ppb).

Carbon dioxide CO2 is a naturally occurring greenhouse gas in the atmosphere. However the amount of it increases when we burn fossil fuels, leading to global warming. Used widely as a measure of the ventilation adequacy of a space.
Global warming:the theory that the average temperatures around the world have begun to rise, and will continue to rise, because of an increase of certain gases (called greenhouse gases) in Earth's atmosphere.
carbon neutral If a business went carbon neutral, they would do all they could to avoid emitting greenhouse gasses. However, it would be impossible to eliminate all of them.
greenhouse effect A popular term used to describe the roles of water vapor, carbon dioxide, and other trace gases in keeping the Earth's surface warmer than it would be otherwise.
greenhouse gas Gases such as carbon dioxide and methane that trap heat in the atmosphere. These gases are emitted from a variety of natural sources like forest fires, and human sources like the combustion of gasoline and natural gas.
#9 An international agreement known as the Kyoto Protocol has been negotiated to reduce greenhouse gas emissions, but the US is not participating in it.
Water Vapor: The most abundant greenhouse gas, it is the water present in the atmosphere in gaseous form. Water vapor is an important part of the natural greenhouse effect.
Among these are: Agstar, to reduce methane emissions through manure management; Climate Wise, to lower industrial greenhouse-gas emissions and energy costs; Coalbed Methane Outreach, to boost methane recovery at coal mines; ...
