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: ...
Greenhouse Gases at Record Levels
Prior to the start of the Industrial Revolution, the levels of carbon dioxide in the atmosphere were about 280 parts per million by volume (ppmv). Current levels are about 370 ppmv.
Greenhouse Gases - Any gas that absorbs infrared radiation in the earth's atmosphere.
greenhouse gases: Greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone.
groundwater: Groundwater is the water that flows underground filling soil and flowing out into springs and aquifers.
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 Gases - Those atmospheric components that absorb strongly in the infrared region of the spectrum.
Greenhouse gases
Gases such as carbon dioxide and methane, which tend to trap heat radiating from the Earth's surface, so causing warming in the lower atmosphere.
Greenhouse Gases: Atmospheric gases such as carbon dioxide, methane, chlorofluorocarbons, nitrous oxide, ozone, and water vapor that slow the passage of re-radiated heat through the Earth's atmosphere. ( See also ClimateChange.ca.gov Glossary.
Greenhouse Gases (GHG) are those gases contributing to the greenhouse effect and are carbon dioxide, chlorofluorocarbons (CFCs), nitrous oxides, and methane.
The greenhouse gases
Water vapor (H2O) causes about 60% of Earth's naturally-occurring greenhouse effect. Other gases influencing the effect include carbon dioxide (CO2) (about 26%), methane (CH4), nitrous oxide (N2O) and ozone (O3) (about 8%).
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 Gases
Gases responsible for the greenhouse effect. These gases include: carbon dioxide (CO2); methane (CH4); nitrous oxide (N2O); chlorofluorocarbons (CFxClx); and tropospheric ozone (O3).

The GREENHOUSE GASES are very important and are mainly:
water vapour
occurs naturally in the atmosphere.
Emissions cap A limit placed on companies regarding the amount of greenhouse gases they are permitted emit (see Carbon Offsetting). Emission Controls Any measure that reduces emissions into air, water or soil.
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 tax A carbon tax is a tax on emissions of carbon dioxide ( CO₂ ) and other greenhouse gases. It is a type of pollution tax that both gives incentives to pollute less and helps assign the costs of pollution to the polluters.
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 can be done by a sheet of glass or a layer of some gases, known as greenhouse gases. The greenhouse effect is beneficial to mankind as well as harmful as, without it, the surface of the earth would be around 33ºC cooler than it is.
#10 Protecting the world's climate by stabilizing atmospheric concentrations of greenhouse gases will require enormous reductions in current emissions.
The combustion of fossil fuels, including the coal-burning power plants, automobile exhausts, factory smokestacks, and other waste vents of the human environment contribute about 22 billion tons of carbon dioxide and other greenhouse gases into the ...
A metric measure used to compare the emissions from various greenhouse gases based upon their global warming potential (GWP). Carbon dioxide equivalents are commonly expressed as 'million metric tonnes of carbon dioxide equivalents (MMTCDE)'.
Global warming has occurred in the distant past as the result of natural influences, but the term is most often used to refer to the warming predicted to occur as a result of increased emissions of greenhouse gases.
A general warming effect felt on Earth's surface, produced by greenhouse gases.
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 effect produced as greenhouse gases allow incoming solar radiation to pass through the Earth's atmosphere, ...
Gradual global climatic warming is caused by a build-up of greenhouse gases from increased carbon dioxide emissions from fossil fuels burned by cars, industry and power plants as well as from CFCs, ...
Greenhouse gases include, but are not limited to, water vapor, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), ozone (O3 ), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), ...
Atmospheric concentrations of greenhouse gases are usually expressed in parts per million (ppm) or parts per billion (ppb). For example, atmospheric CO2 emissions have risen from approximately 280ppm to 385ppm in the last 250 years.
Global Warming - A process that raises the air temperature in the lower atmosphere due to heat trapped by greenhouse gases, such as carbon dioxide, methane, nitrous oxide, CFCs and ozone.
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.
Carbon Footprint: The total amount of carbon dioxide and other greenhouse gases emitted over the full lifecycle of a product or service, expressed as grams of CO2 equivalents.
carbon offset = (as defined in NCOS) a reduction in greenhouse gases, or enhancement of greenhouse gas removal from the atmosphere by sinks, relative to a business-as-usual baseline.
Carbon Footprint: a measure of the amount of carbon emissions, or greenhouse gases (gases such as carbon dioxide and methane that trap the heat of the sun in the Earth's atmosphere) produced, ...
emissions cap - a limit on the amount of greenhouse gases that a company or country can legally emit.
endangered species - species in danger of extinction throughout all or a significant part of its range.
Emissions cap - a limit placed on companies regarding the amount of greenhouse gases it can emit.
Environmentally preferable - products or services that have a lesser or reduced effect on the environment.
A measure of your impact on the environment in terms of the amount of greenhouse gases produced, measured in units of carbon dioxide.

While humans are not significantly increasing its concentration, it contributes to the enhanced greenhouse effect because the warming influence of greenhouse gases leads to a positive water vapor feedback.
Carbon Footprint - A cumulative measure of the impact a product, service, activity, company, individual or other entity has on the environment, in terms of the amount of greenhouse gases produced, and measured in units of carbon dioxide.
It acts like glass in a greenhouse, doing the same as my feathers do when I'm swimming in the very cold sea: my feathers keep me warm, the glass in the greenhouse keeps the plants inside warm, and the carbon dioxide and other greenhouse gases keep ...
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, chlorofluorocarbons and ozone.
When present in the atmosphere, therefore, the gas contributes to the greenhouse effect (heating of the earth's atmosphere). The principal greenhouse gases are water vapour, carbon dioxide, methane, nitrous oxide, ozone, ...
The greenhouse gases of most concern are carbon dioxide, methane, and nitrous oxides. If these gases in our atmosphere double, the earth could warm up by 1.5 to 4.
