Gases responsible for greenhouse effect
Gases responsible for greenhouse effect-From 1990 to 19, the total warming effect from greenhouse gases added by humans to the Earth's atmosphere increased by 45 percent The warming effect associated with carbon dioxide alone increased by 36 percentGreenhouse effect, a warming of Earth's surface and troposphere (the lowest layer of the atmosphere) caused by the presence of water vapour, carbon dioxide, methane, and certain other gases in the air Of those gases, known as greenhouse gases, water vapour has the largest effect The origins of the term greenhouse effect are unclear French mathematician Joseph
Carbon dioxide (CO2) Carbon dioxide is the primary greenhouse gas, responsible for about threequarters of emissions It can linger inIn general, fluorinated gases are the most potent and longest lasting type of greenhouse gases emitted by human activities There are four main categories of fluorinated gases—hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF 6 ), and nitrogen trifluoride (NF 3 )Most of the greenhouse gases are responsible to cause the greenhouse effect by radiating energy in all directions The earth's surface absorbs the most part of this radiation that results into its warming The strength of this effect depends upon the atmosphere's temperature and the amount of greenhouse gases present in the atmosphere
Explanation Greenhouse effect is the naturally occurring phenomenon that is responsible for heating of Earth's surface and atmosphere Carbon dioxide and methane are the biggest contributors of greenhouse effect Carbon dioxide and methane account for 564% and 163% greenhouse effect, respectively Ozone is responsible for 10%, nitrous oxide 54% and halocarbonsGreenhouse 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, halogenatedIn terms of the net increase in the greenhouse effect due to humanproduced greenhouse gases, CO 2 is responsible for the lion's share CO 2 from fossil fuel burning alone is more than half the net force If you add CO 2 from fossil fuel burning, deforestation, and other minor sources, this comes to a little more than threefourths of the net
Water vapor feedback can also amplify the warming effect of other greenhouse gases, such that the warming brought about by increased carbon dioxide allows more water vapor to enter the atmosphere The difference in an atmosphere with a strong water vapor feedback and one with a weak feedback is enormous, Dessler saidModels showed that approximately 93% of crop losses over the rest of the century could be caused by non–carbon dioxide emissions, the mostGreenhouse gases that occur both naturally and from human activities include water vapor, carbon dioxide (CO 2 ), methane (CH 4 ), nitrous oxide (N 2 O) and ozone (O 3) Other greenhouse gases have essentially no natural sources, but are side products of industrial processes or manufactured for human purposes such as cleaning agents
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 vaporGreenhouse gases are gases that can trap heat They get their name from greenhouses A greenhouse is full of windows that let in sunlight That sunlight creates warmth The big trick of a greenhouse is that it doesn't let that warmth escape That's exactly how greenhouse gases act They letGreenhouse 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

Sciences, and Julia Khusnutdinova, a postdoctoral researcher in his lab, work together on a metal complexCarbon dioxide Of 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 humansThe 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 gases because they absorb heat
The most wellknown greenhouse gas is Carbon Dioxide, also known as CO2 Other greenhouse gases are methane, carbon monoxide, sulphur dioxide, nitrous oxide and water vapourLet'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 ResourcesChlorofluorocarbons (CFCs) Synthetic compounds entirely of industrial origin used in a number of applications, but now largely regulated in production and release to the atmosphere by international agreement for their ability to contribute to destruction of
The greenhouse effect happens when certain gases, which are known as greenhouse gases, accumulate in Earth's atmosphere Greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), ozone (O3), and fluorinated gasesThe enhanced greenhouse effect What has scientists concerned now is that over the past 250 years, humans have been artificially raising the concentration of greenhouse gases in the atmosphere at an everincreasing rate, mostly by burning fossil fuels, but also from cutting down carbonabsorbing forestsCurrently, carbon dioxide accounts for more than 60 percent of the enhanced greenhouse effect caused by the increase of greenhouse gases, and the level of carbon dioxide in the atmosphere is
The result is Earth's temperatures higher than they would be in the absence of these gases The atmospheric gases and a greenhouse work in quite different ways, but the resulting effect, higher temperature in both cases, has led to the nomenclature "greenhouse gases" for the atmospheric gases responsible for the atmospheric warming effectThe greenhouse effect is not the same on all planets, and differs dramatically based on the thickness and composition of the atmosphereThree planets that show how dramatically the conditions of a planet can change with the different levels of the greenhouse effect are Venus, Earth, and Mars Earth, Mars, and Venus are different distances from the Sun Venus is theThe gases in the atmosphere that absorb radiation are known as greenhouse gases (abbreviated as GHG) because they are largely responsible for the greenhouse effect The greenhouse effect, in
Estimated Reading Time 7 minsThe greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere Radiatively active gases (ie, greenhouse gases) in a planet's atmosphere radiate energy in all directionsPart of this radiation is directed towards the surface, thus warming itThe Greenhouse Effect The picture below shows the greenhouse effect Light from the sun passes through the atmosphere and is absorbed by the Earth's surface, warming it Greenhouse gases, like carbon dioxide, act like a blanket, trapping heat near the surface and raising the temperature It is a natural process that warms the planet
The most abundant greenhouse gases responsible for the greenhouse effect in the atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone These greenhouse gases keep the surface of the Earth approximately 60F warmer than we would expect without these gasesMost 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 cycleThe primary greenhouse gases in Earth's atmosphere are CO 2, CH 4, water vapour, nitrous oxide, and ozone Greenhouse gases cause the greenhouse effect on earth by
Greenhouse gases are responsible for the Greenhouse Effect But before we investigate that, let's find out what greenhouse gases are Can you name any of them?8 rowsGreenhouse gas Chemical formula Global Warming Potential, 100year time horizon AtmosphericGreenhouse 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) cooler
The greenhouse effect is a natural process responsible for keeping the earth at the temperature needed to sustain life Acting just like the glass walls of a greenhouse, gases like carbon dioxide, methane, and nitrous oxide trap the sun's heat in the atmosphere and prevent itThe greenhouse effect accounts for global climate change, and carbon dioxide is one of the chief greenhouse gases responsible According to the Intergovernmental Panel on Climate Change, carbon
