Greenhouse Gases Introduction Certain gases in Earth's atmosphere—particularly carbon dioxide (CO 2), methane (CH 4), and water vapor (H 2)—trap energy from solar radiation and so keep Earth warmer than it would be otherwiseThese gases are termed greenhouse gases, and the warming they create is termed the greenhouse effect or greenhouse warmingData for the past 00 years show that the atmospheric concentrations of CO 2, CH 4, and N 2 O – three important longlived greenhouse gases – have increased substantially since about 1750 Rates of increase in levels of these gases are dramatic CO 2, for instance, never increased more than 30 ppm during any previous 1,000year period in this record but has already risen by 30Greenhouse 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 in the atmosphere percentage- The greenhouse effect happens when certain gases, which are known as greenhouse gases, accumulate in Earth's atmosphere Greenhouse gases include carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), ozone (O 3), and fluorinated gasesAs greenhouse gas emissions from human activities increase, they build up in the atmosphere and warm the climate, leading to many other changes around the world—in the atmosphere, on land, and in the oceans The indicators in other chapters of this report illustrate many of these changes, which have both positive and negative effects on people, society, and the environment—including plants and animals Because many of the major greenhouse gases stay in the atmosphere

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 effect include water vapor, The powerful greenhouse gases tetrafluoromethane and hexafluoroethane have been building up in the atmosphere from unknown sources Now, modelling suggests that China's aluminium industry is a saw the highest concentration of greenhouse gases in Earth's atmosphere on record, along with unprecedented global sea levels and average global temperatures
Each layer of the atmosphere with greenhouse gases absorbs some of the heat being radiated upwards from lower layers It reradiates in all directions, both upwards and downwards;To learn more about the ocean heat and The greenhouse effect works much the same way on Earth Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse These heattrapping gases are called greenhouse gases During the day, the Sun shines through the atmosphere Earth's surface warms up in the sunlight At night, Earth's surface cools, releasing heat back into the air But some of the heat is trapped by the greenhouse gases in the atmosphere
242 Atmospheric Chemistry and Greenhouse Gases Model calculations of the abundances of the primary greenhouse gases by year 2100 vary considerably across the SRES scenarios in general A1B, A1T, and B1 have the smallest increases of emissions and burdens;Atmospheric greenhouse gases (GHGs), such as carbon dioxide (CO2) and methane (CH4), are important climate forcing agents due to their significantOverview of Greenhouse Gases Carbon dioxide (CO2) Carbon dioxide enters the atmosphere through burning fossil fuels (coal, natural gas, and oil), Methane (CH4) Methane is emitted during the production and transport of coal, natural gas, and oil Methane emissions Nitrous oxide (N2O) Nitrous

Greenhouse gas concentrations in the atmosphere that contribute to climate change are the highest ever recorded — and that's going back 800,000 years Scientists at the National Oceanic and Atmospheric Administration reported that the concentration of carbon dioxide, one of the primary greenhouse gases, hit 4125 parts per million inGreenhouse Gases and Temperature A greenhouse gas (GHG) is any gas in the atmosphere that absorbs and emits radiation in the thermal infrared range These are the fundamental cause of the greenhouse effect, which results in increased temperatures on Earth The greenhouse effect occurs as the gases reach Earth's surfaceGreenhouse 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 light

Greenhouse gas emissions and atmospheric concentrations have increased over the past 150 years Emissions of several important greenhouse gases that result from human activity have increased substantially since largescale industrialization began in the mid1800s Most of these humancaused (anthropogenic) greenhouse gas emissions were carbon dioxide (CO2)Even if greenhouse gas concentrations stabilized today, the planet would continue to warm by about 06°C over the next century because of greenhouses gases already in the atmosphere See Earth's Big Heat Bucket, Correcting Ocean Cooling, and Climate Q&A If we immediately stopped emitting greenhouse gases, would global warming stop?Carbon dioxide is the main longlived greenhouse gas in the atmosphere Concentrations reached 4055 ppm in 17, 146% of the preindustrial era (before 1750) The increase in

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, etc The amounts of GHGs are balanced in the atmosphere naturally by many physical, chemicalIn order, the most abundant greenhouse gases in Earth's atmosphere are Water vapor ( H 2O) Carbon dioxide ( CO 2) Methane ( CH 4) Nitrous oxide ( N 2O) Ozone ( O 3) Chlorofluorocarbons (CFCs) Hydrofluorocarbons (includes HCFCs and HFCs)Earth's greenhouse gases trap heat in the atmosphere and warm the planet The main gases responsible for the greenhouse effect include carbon dioxide, methane, nitrous

Greenhouse gases A natural or manmade gas that traps heat in the Earth's atmosphere and contributes to the greenhouse effect The main greenhouse gases are water vapour, carbon dioxide (CO 2 ), methane (CH 4 ), nitrous oxide (N 2 O), ozone and industrial gases such as chlorofluorocarbons (CFCs) Which of these actions has contributed to the increase of greenhouse gases in the atmosphere? Nitrous oxide A powerful greenhouse gas produced by soil cultivation practices, especially the use of commercial and organic fertilizers, fossil fuel combustion, nitric acid production, and biomass burning Chlorofluorocarbons (CFCs) Synthetic compounds entirely of industrial origin used in a number of applications, but now largely regulated in production and release to the atmosphere
