The greenhouse effect keeps the temperatures on our planet mild and suitable for living things Greenhouse gases (GHG) include carbon dioxide, water vapor, methane, ozone, nitrous oxide and fluorinated gases These molecules in our atmosphere are called greenhouse gasesOf the greenhouse gases, carbon dioxide (CO 2) is the most prominent Sources of atmospheric CO 2 include volcanoes, the combustion and decay of organic matter, respiration by aerobic (oxygenusing) organisms, and the burning of fossil fuels, clearing of land, and production of cement by humans These sources are balanced, on average, by a setThe answer may not be as clear as one might assume, because the top emitters change depending on how the data is collected and what

The greenhouse effect happens when certain gases—known as greenhouse gas es—collect in Earth's atmosphere These gases, which occur naturally in the atmosphere, include carbon dioxide, methane, nitrogen oxide, and fluorinate d gases sometimes known as chlorofluorocarbons (CFCs)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 factorsCarbon dioxide (CO 2) is the most important greenhouse gas, but not the only one – gases such as methane and nitrous oxide are also a driver of global warming Carbon dioxideequivalents (CO 2 eq) try to sum all of the warming impacts of the different greenhouse gases together in order to give a single measure of total greenhouse gas emissions
The term "greenhouse gases," or GHGs, covers a wide variety of gases that, once they are released into the atmosphere, trap the sun's heat When the sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and trapped in the lower atmosphere, heating the Earth Aside from water vapour, the four principal greenhouse gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and the halocarbons or CFCs (gases containing fluorine, chlorine and bromine)Since the Industrial Revolution, rising emissions of greenhouse gases—including carbon dioxide, methane, nitrous oxide, and others—have been the driving force behind climate change Who is responsible for emitting the most greenhouse gases?
Greenhouse gases are gases—like carbon dioxide (CO 2), methane, and nitrous oxide—that keep the Earth warmer than it would be without them The reason they warm the Earth has to do with the way energy enters and leaves our atmosphere When energy from the sun first reaches us, it does so mainly as lightMultiple gases contribute to the greenhouse effect that sets Earth's temperature over geologic time Small changes in the atmospheric concentration of these gases can lead to changes in temperature that make the difference between ice ages when mastodons roamed the Earth, and the sweltering heat in which the dinosaurs lived These gases are known as greenhouse gases Below are the most important greenhouse gases that influence Earth's climate system Water vapor (H2O) is the strongest greenhouse gas, and the concentration of this gas is largely controlled by the temperature of the atmosphere As air becomes warmer, it can hold more moisture or water vapor

Carbon dioxide Water Vapour Methane Ozone Nitrous oxide Chlorofluorocarbons Greenhouse gases Sources As greenhouse gases are essential for the existence of life, they are present in the atmosphere in a trace amount Natural sources of GHGs are volcanos, respiration by living organisms, decay and combustion of organic matter, etcGreenhouse gas, any gas that has the property of absorbing infrared radiation (net heat energy) emitted from Earth's surface and reradiating it back to Earth's surface, thus contributing to the greenhouse effect Carbon dioxide, methane, and waterThe ordinance shall provide canopy credits of one and onehalf the area normally projected for trees planted to absorb or intercept air pollutants, tree species that produce lower levels of reactive volatile organic compounds, or trees that act to reduce air pollution or greenhouse gas emissions by conserving the energy used to cool and heat

Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs) The absorbed energy warms the atmosphere and the surface of the Earth Greenhouse gases include carbon dioxide, methane, and nitrous oxides Scientists have determined that carbon dioxide's warming effect helps stabilize Earth's atmosphere Remove carbon dioxide, and the terrestrial greenhouse effect would collapse Without carbon dioxide, Earth's surface would be some 33 °C (59 °F) coolerCarbon dioxide (CO 2) makes up the vast majority of greenhouse gas emissions from the sector, but smaller amounts of methane (CH 4) and nitrous oxide (N 2 O) are also emitted These gases are released during the combustion of fossil fuels, such as coal, oil, and natural gas, to

Virginia ranks third in the nation, after Colorado and New Mexico, in coalbed methane proved reserves, and two Virginia coalbed methane fields, Oakwood and Nora, are ranked among the top 100 natural gas fields in the United States The ports in Virginia's Norfolk Customs District processed about 35% of US coal exports in 19, making it theMethodologies for Addressing the Issue Greenhouse gases are emitted from the soil, belowground roots, and soilemergent plant structures, while CO 2 is taken up by photosynthetic tissue The scale selected for greenhouse gas assessments matter tremendously We use a suite of approaches to assess greenhouse gas fluxes, including dark staticThese "greenhouse gases" allow the sun's rays to pass through and warm the planet but prevent this warmth from escaping the atmosphere into space Without them, Earth would be too cold to sustain life as we know it When we talk about greenhouse gases, we're referring to carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons and sulphur hexafluoride

Greenhouse Effect How Does Climate Change Work
What are "greenhouse gases?" The transparent windows of a greenhouse (or a car parked in the sunlight) transmit the warming visible rays of the sun, prevent the resulting warm air from leaving, and hence maintain a warmer environment inside than outside the structure Scientists attribute the global warming trend observed since the mid th century to the human expansion of the "greenhouse effect" 1 — warming that results when the atmosphere traps heat radiating from Earth toward space Certain gases in the atmosphere block heat from escaping Longlived gases that remain semipermanently in the atmosphere and do not respond Some of the greenhouse gases in the atmosphere are caused by humans Whenever we burn anything, such as— gasoline in our cars and trucks, jet fuel in our planes, coal in our factories or powerplants, trees to clear the land for farming —we pollute our atmosphere with carbon dioxide and carbon monoxide Although carbon monoxide does not
