A gas in Earth's atmosphere that traps heat and can contribute to global warming. Carbon dioxide and methane are the two most important.
A gas that absorbs infrared radiation and in turn emits it in the atmosphere. The net effect is a local trapping of energy and a tendency to warm the earth's surface. Water vapour (H2O), carbon dioxide (CO2) methane (CH4), nitrous oxide (N2O) and ozone (O3) are the primary greenhouse gases in the Earth's atmosphere.
A gas which acts like the glass in a greenhouse, trapping heat in the earth's atmosphere, to cause the greenhouse effect. Two of the most common greenhouses gases are carbon dioxide and methane.
a gas involved in the greenhouse effect.
A gas, such as water vapour, carbon dioxide, methane, CFCs and HCFCs, that absorbs and re-emits infrared radiation, warming the earth's surface and contributing to climate change.
these are gases that are found in the atmosphere such as carbon dioxide and methane. The presence of these gases allows the greenhouse effect to occur. There are however increasing concentrations of these gases due to the activity of humans. It is this increase that is having a negative effect by reflecting more heat back into the atmosphere and consequently leading to global warming and a change in our climate.
any gas that absorbs infrared radiation in the atmosphere.
Greenhouse gases are those gaseous constituents of the atmosphere, both natural and anthropogenic, that absorb and emit radiation at specific wavelengths within the spectrum of infrared radiation emitted by the Earth's surface, the atmosphere, and clouds. This property causes the greenhouse effect. Water vapor (H2O), carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4), and ozone (O3) are the primary greenhouse gases in the Earth's atmosphere. Moreover there are a number of entirely human-made greenhouse gases in the atmosphere, such as the halocarbons and other chlorine- and bromine-containing substances, dealt with under the Montreal Protocol.
A gas in the Earth's atmosphere that contributes to the greenhouse effect. The most important greenhouse gases are carbon dioxide, methane and water vapour.
Those gases that contribute to the greenhouse effect by trapping heat within the earth's atmosphere. The chief greenhouse gases are carbon dioxide and water vapor. Other potentially important trace gases are chlorofluorocarbons, methane, ozone, and nitrous oxide. See Watson et al. (1990) for a general overview and Ramanathan et al. (1985) and Ramanathan et al. (1987) for information on the trace gases.
The tiny fraction of the atmosphere that traps heat. The main greenhouse gases given off by human activity are carbon dioxide, methane and nitrous oxide. Others are hydrofluorocarbons, perfluorocarbons and sulfur hexachloride. Water vapor also acts as a greenhouse gas.
The atmosphere consists of 78% nitrogen and 21% oxygen - but it is the so-called 'trace' gases in the remaining fraction that absorb most of the heat. These are often called 'greenhouse gases'. Some of these gases occur naturally whilst others are man-made. Examples include CO2, CH4, N2O, O3, and CFC's. In the last few hundred years human activities have increased the quantities of greenhouse gases present in the atmosphere.

The Kyoto Protocol covers a basket of six greenhouse gases (GHGs) produced by human activities: carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride. Annex I Parties' emissions of these gases taken together are to be measured in terms of carbon dioxide equivalents on the basis of the gases' global warming potential. An important natural GHG that is not covered by the protocol is water vapour.
