The three most important greenhouse gases in the atmosphere are carbon dioxide (CO 2), methane (CH 4) and nitrous oxide (N 2 O) While carbon dioxide is the greenhouse gas we hear the most about, methane and nitrous oxide have greater global warming potential (GWP)Methane has a GWP of 25 for a 100year period and nitrous oxide has a GWP of 298The AGGI in was 147, which means that we've turned up the warming influence from greenhouse gases by 47% since 1990 It took ~240 years for the AGGI to go from 0 to 1, ie, to reach 100%, and 30 years for it to increase by another 47% In terms of CO 2 equivalents, the atmosphere in contained 504 ppm, of which 412 is CO 2 aloneHowever some gases in the atmosphere, called greenhouse gases, trap escaping thermal energy This causes some of the thermal energy to pass back to the surface This is called the greenhouse

"There is no sign of a slowdown, let alone a decline, in greenhouse gases concentration in the atmosphere despite all the commitments under the Paris agreement on climate change," said WMOEffects of increased greenhouse gases The growing concentrations of humangenerated GHGs have resulted in an increased absorption, largely in the lower atmosphere, of the heat radiated from Earth's surface, causing an increase in the global (land and ocean) mean surface temperature of 085 ± 0 °C from 10 to 12 ( Stocker et al 13a The graphs show monthly mean carbon dioxide measured at Mauna Loa Observatory, Hawaii The carbon dioxide data on Mauna Loa constitute the longest record of direct measurements of CO 2 in the atmosphere They were started by C David Keeling of the Scripps Institution of Oceanography in March of 1958 at a facility of the National Oceanic and
When Earth first formed, Earth's atmosphere may have contained more greenhouse gases and CO 2 concentrations may have been higher, with estimated partial pressure as large as 1,000 kPa (10 bar ), because there was no bacterial photosynthesis to reduce the gas to411 Sources of Greenhouse Gases 243 412 Atmospheric Chemistry and Feedbacks 245 413 Trace Gas Budgets and Trends 246 414 Atmospheric Lifetimes and TimeScales 247 42 Trace Gases Current Observations, Trends and Budgets 248 421 NonCO 2 Kyoto Gases 248 4211 Methane (CH 4) 248 4212 Nitrous oxide (N 2O) 251 4213Based on greenhouse climate models and other considerations, it is possible that atmospheric carbon dioxide concentrations may double from their late 1700s level of 275 ppmv by the years 30–50 By 15, atmospheric carbon dioxide concentrations had surpassed 400 ppmv for the first time in 800,000 years
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 warming effect caused by greenhouse gases globally Why is this indicator important?Greenhouse 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 surfaceThe naturally occurring gases in the atmosphere, showing where the highest concentration of gases are and the percentages of each accurately The greenhouse gases in the atmosphere (rememberthese are also naturally occurring – just in a harmful percentage) Each continent and the areas of highest global emission within The Ozone Hole

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 concentration of greenhouse gases can make the atmosphere essentially opaque in a particular band If the atmosphere absorbs 100 percent of the radiation in a band the absorption will not be increased when additional greenhouse gases are added The atmosphere would then be said to be saturated in that particular frequency band However fullAnthropogenic greenhouse gases Since the start of the Industrial Revolution in the mid18th century, human activities have greatly increased the concentrations of greenhouse gases in the atmosphere Consequently, measured atmospheric concentrations of CO 2 are many times higher than preindustrial levels

Greenhouse gases are gases in the earth's atmosphere that trap heat During the day, the sun shines through the atmosphere, warming the earth's surface 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 That's what keeps the earth's temperature at Greenhouse gases differ in the way they affect the climate system In order to sum the effects of the individual greenhouse gases and other forcing agents in the atmosphere, the socalled 'greenhouse gas equivalent concentration' has been defined This is the concentration of CO 2 that would cause the same amount of radiative forcing as aI am often asked how carbon dioxide can have an important effect on global climate when its concentration is so small – just 0041 percent of Earth's atmosphere
