Greenhouse Gases - the gases that absorb terrestrial radiation and contribute to the greenhouse effect; the main greenhouse gasses are water vapor, methane, CO2 and ozone.
Greenhouse gases: Gases in the atmosphere that are effective absorbers of infrared radiation and ineffective at absorbing solar radiation.
Greenhouse gases Infrared-absorbing gases that contribute to the greenhouse effect in the Earth-atmosphere system. The main greenhouse gas is water vapor; others are carbon dioxide, ozone, methane, and nitrous oxide. ...

Greenhouse gases- Gases in the atmosphere that trap heat.
Heat- The energy transferred from a hotter object to a cooler one
Humidity- A measure of the amount of water vapor in the air.
Without these greenhouse gases the earth's average surface temperature would be about 33 degrees Celsius cooler. Click here for more information.

Global warmingA theory that increased concentrations of greenhouse gases are causing an elevation in the Earth's surface temperature. Good visibilityMore than 10 kilometers.
Global WarmingAn overall increase in world temperatures which may be caused by additional heat being trapped by greenhouse gases.
There is concern that increasing concentrations of greenhouse gases, including carbon dioxide, methane, and manmade chlorofluorocarbons, may enhance the greenhouse effect and cause global warming.
This warming is likely due to the increase of so called "greenhouse gases" -- such as CO2, methane and CFCs (chloro-fluorocarbons). These gases absorb outgoing heat from our planet and "reflect" it back to Earth.
Greenhouse gases are transparent to certain wavelengths of the sun's radiant energy, allowing them to penetrate deep into the atmosphere or all the way into the Earth's surface.
carbon dioxide equivalence"The contribution of various greenhouse gases to the enhancement of the natural greenhouse effect, either in terms of atmospheric concentrations of carbon dioxide or in terms of emission rates of carbon dioxide.
greenhouse effect: a natural occurrence caused by certain greenhouse gases in the Earth's atmosphere.
CH4 is among the six greenhouse gases to be curbed under the Kyoto Protocol.

A colourless odourless gas. One of the greenhouse gases
Ceiling
The height above the ground of the base of the lowest layer of clouds, when at least clouds cover 60 percent of the sky.
Greenhouse Effect- the heating of the earth's atmosphere caused by imbalances in the atmosphere's radiation cycle, characterized by so called greenhouse gases such as water vapor and carbon dioxide, ...
Enhanced greenhouse effect - The natural greenhouse effect has been enhanced by man's emissions of greenhouse gases. Increased concentrations of carbon dioxide, methane and nitrous oxide trap more infra-red radiation, so heating up the atmosphere.
elements (eccentricity, obliquity of the ecliptic, precession of equinoxes), natural internal processes of the climate system, or anthropogenic forcing (for example, increasing atmospheric concentrations of carbon dioxide and other greenhouse gases).
