Atmosphere Greenhouse gases can also reabsorb solar radiation reflected or reemitted from Earth's surface, trapping the heat in our atmosphere instead of letting it escape to space The Greenhouse Effect is a natural process essential for life on Earth, because itGreenhouse 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) coolerMeasurements of greenhouse gases (GHGs), whether performed in the atmosphere, or over terrestrial or marine ecosystems, have led to a fundamental understanding of the Earth System during the last century Nevertheless, we still do not fully understand global greenhouse gas cycling Up to date measurements of GHG are still rare (as observation

What is the most common greenhouse gas in the atmosphere-Atmospheric Concentrations and Trends of Other Gases that Influence the Radiative Budget Ozone (O3) is an effective greenhouse gas in the upper troposphere and lower stratosphere Significant decreases in total column O3 have been observed throughout the year during the last one to two decades, and at all latitudes except the tropics,This occurs when chemical reactions in the atmosphere produce or destroy greenhouse gases, including tropospheric ozone Indirect effects also occur when a gas influences atmospheric lifetimes of other gases or affects atmospheric processes like cloud formation that alter Earth's radiative energy balance by increasing Earth's albedo

There are two types of emissions that impact on the environment Greenhouse gas emissions, such as carbon dioxide (CO 2), which can trap additional heat from the sun in the earth's atmosphere, causing the 'greenhouse effect' and climate changeCO 2 is the main greenhouse gas produced by motor vehicles In 17, the average combined CO 2 emissions for a new light vehicle sold inWhat are greenhouse gases?The major Greenhouse Gas, carbon dioxide, emitted naturally and by the burning of fossil fuels, stays in the atmosphere a long time Its warming effect occurs even when the sky is clear and dry Climate scientists are so concerned about carbon dioxide because the more carbon dioxide in the atmosphere, the hotter the earth will become, changing

Greenhouse gases are gases in the Earth's atmosphere that produce the greenhouse effect Changes in the concentration of certain greenhouse gases, from human activity (such as burning fossil fuels), increase the risk of global climate change Greenhouse gases include water vapor, carbon dioxide (CO 2 ), methane, nitrous oxide, halogenatedGreenhouse Gas Concentrations Graphing Tool Instruments at air sampling stations around the world have been checking the amounts of different gases in Earth's atmosphere for decades Many stations have instruments mounted at the top of tall towers to measure the abundance of gases in air in real time In some locations, scientists orAnd gases persist for different amounts of time in the atmosphere

Most of these humancaused (anthropogenic) greenhouse gas emissions were carbon dioxide (CO2) from burning fossil fuels Concentrations of CO2 in the atmosphere are naturally regulated by many processes that are part of the global carbon cycle The flux, or movement, of carbon between the atmosphere and the earth's land and oceans is dominated byThe ratio of water component of the greenhouse effect to the CO 2 component is about 159 to 1 This means that the water vapor content of the atmosphere has to only fall from 041 percent to 0407 to wipe out the greenhouse effect of all the CO 2 in the atmosphere Given this sensitivity to the water vapor content it is clear that we really do not know whether the greenhouse gasSome of these gases (like methane) are considerably more shortlived in the atmosphere than CO 2, persisting for decades rather than centuries Such complications are often dealt with through the concept of global warming potential (GWP), which takes into account both the radiative properties of a particular greenhouse gas molecule and the

Where Do Greenhouse Gas Emissions Come From University Of California
Greenhouse gases in the atmosphere, including water vapour, carbon dioxide, methane, and nitrous oxide, absorb heat energy and emit it in all directions (including downwards), keeping Earth's surface and lower atmosphere warm Adding more greenhouse gases to the atmosphere enhances the effect, making Earth's surface and lower atmosphereWater vapor is naturally present in the atmosphere and has a strong effect on weather and climate As the planet gets warmer, more water evaporates from the Earth's surface and becomes vapor in the atmosphere Water vapor is a greenhouse gas, so more water vapor in the atmosphere leads to even more warming265–298 Fluorinated gases A group of gases that contain fluorine, including hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride, among other chemicals These gases are emitted from a variety of industrial processes and commercial and household uses and do not occur naturally

Additional trace gases produced by industrial activity that have greenhouse properties include nitrous oxide (N 2 O) and fluorinated gases (halocarbons) The latter includes sulfur hexafluoride, hydrofluorocarbons (HFCs), and perfluorocarbons (PFCs)These greenhouse gases are used in aerosol cans and refrigeration All of these human activities add greenhouse gases to the atmosphere, trapping more heat than usual and contributing to global warming Effects of Global Warming Even slight rises in average global temperatures can have huge effectsSince measurements first started at Mauna Loa, Hawaii, atmospheric levels of CO 2 have risen from 315 ppm in 1958 to over 400 ppm today Concentrations are expected to stay above 400 ppm for many generations, because CO 2 can remain in the atmosphere for hundreds of years CO 2 is a longlived greenhouse gas responsible for roughly 65 percent of the total

The greenhouse gases in the atmosphere can both absorb and reradiate much of the outgoing heat energy The atmospheric concentrations of some greenhouse gases are being affected directly by human activities namely carbon dioxide (CO 2 ), methane (CH 4 ), nitrous oxide (N 2 O), ozone (O 3 ), and synthetic gases, such as chlorofluorocarbons (CFCs) and hydrofluorocarbons (HFCs)Greenhouse gases reflect infrared radiation, so some of the heat leaving the Earth bounces off the greenhouse gases in our atmosphere and comes back to the Earth's surface This is called the "greenhouse effect," in a comparison to the heattrapping glass on a greenhouse The greenhouse effect is not a bad thingThis graph shows the heating imbalance in watts per square meter relative to the year 1750 caused by all major humanproduced greenhouse gases carbon dioxide, methane, nitrous oxide, chlorofluorocarbons 11 and 12, and a group of 15 other minor contributors

The 'greenhouse effect' is the warming of climate that results when the atmosphere traps heat radiating from Earth toward space Certain gases in the atmosphere resemble glass in a greenhouse, allowing sunlight to pass into the 'greenhouse,' but blocking Earth's heat from escaping into space The gases that contribute to the greenhouse effectLet's consider the principal GHGs one at a time, starting with water vapor, the most abundant greenhouse gas in the atmosphere according to NOAA's National Climatic Data Center (NCDC) Water Vapor Carbon Dioxide (CO 2) Methane (CH 4) Nitrous oxide (N 2 O) Fluorinated Gases (HFCs, PFCs, SF 6) References and ResourcesComparing greenhouse gases All greenhouse gases absorb energy, but different gases have different effects on warming Carbon dioxide, methane and nitrous oxide remain in the atmosphere for long enough to allow them to mix together As a result, the gas concentrations are about the same around the globe, regardless of the source or location of the emissions
