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 Gas - Certain gases, such as water vapor, carbon dioxide, and methane, that more effectively trap heat affecting the Earth's surface temperature.
Greenhouse gas Gases such as water vapor, carbon dioxide, and methane, which are relatively transparent to sunlight but absorb and emit longwave 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 Gas A gaseous component of the atmosphere contributing to the greenhouse effect.

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.
greenhouse gas: gases in the atmosphere that are more transparent to the short wavelength radiation (mostly visible light) from the sun, than to the long wavelength radiation (infrared radiation) leaving the Earth.
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.
carbon dioxide concentrationThe amount of carbon dioxide, a heavy, colorless greenhouse gas, per unit of volume.carbon dioxide fluxThe rate of flow for carbon dioxide, a heavy, colorless greenhouse gas.
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.
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.

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.
In this case, the most abundant greenhouse gas is water vapor. 2) Anthropogenic: Additional warming caused by having too much carbon dioxide (CO2).
earth to be warmer than it would have been in the absence of an atmosphere because it receives energy from two sources: the sun and the atmosphere. Radiation is not trapped,and the atmosphere does not behave as a greenhouse and the greenhouse gasses ...
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).
