The perturbation to direct climate forcing (also termed “radiative forcing”) that has the largest magnitude and the least scientific uncertainty is the forcing related to changes in the atmospheric global abundance of long-lived, well mixed greenhouse gases, in particular carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2 O), and halogenated compounds (mainly CFCs).

Which sequence for greenhouse gases is based on GWP? (a) CFC > N2O > CO2 > CH4 (b) CFC > CO2 > N2O > CH 4

Växthusgaser: CO2, N2O, CH4, CCl2F2 (CFC-12) och CCl3F (CFC-11). Hur har koncentrationer av växthusgaser i atmosfären förändrats sedan 1800-talet? Nivån 76 Mt är densamma för utsläpp av CO2, CH4, N2O, CFC och inkl bunker år 2005 som 1990. (Källor: SÅ och Energimynd, rapp 4 s 63) The annual emissions of CO2, CH4 and N2O from the peat were unaffected.

Fluxes of CO2 remained small until full plant development in early summer 2012. In contrast, methane emissions showed only minor variations over time. The annual GHG flux budget was dominated by N2O (48% contribution) and CO2 emissions (44%). CH4 flux contribution to the annual budget was only minor (8%).

Five major gases (carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), CFC-12 and CFC-11) contribute about 96% of the increase in radiative forcing due to long-lived greenhouse gases that has occurred since 1750. But CH 4 also absorbs much more energy than CO 2. The net effect of the shorter lifetime and higher energy absorption is reflected in the GWP. The CH 4 GWP also accounts for some indirect effects, such as the fact that CH 4 is a precursor to ozone, and ozone is itself a GHG. Nitrous Oxide (N 2 O) has a GWP 265–298 times that of CO 2 for a 100-year timescale. The five major greenhouse gases (CO2, CH4, N2O, CFC-12 and CFC-11) account for about 96% of the direct radiative forcing by long-lived greenhouse gas increases since 1750.

CO2 is the most important green-house gas, followed by N2O and CH4 in relative importance. 2011-03-01 · Photocatalysis looks like a panacea to fight all potent greenhouse gases, as photocatalyzed reactions are able to transform or destroy almost all well-mixed, long-lived greenhouse gases – CO 2, CH 4, N 2 O, CFC-12 and CFC-11 – which account for about 96% of the direct radiative forcing, and also short-lived climate forcers like VOCs, NOx, BC and soot that have an important contribution to climate change. LLGHGs (CO 2, CH 4, N2O, CFC-12 and CFC-11) account for about 96% of the direct radiative forcing since 1750.

Global warming potential is the heat absorbed by any greenhouse gas in the atmosphere, as a multiple of the heat that would be absorbed by the same mass of carbon dioxide. GWP is 1 for CO 2. For other gases it depends on the gas and the time frame. Carbon dioxide equivalent is calculated from GWP. It can be measured in weight or concentration. For any amount of any gas, it is the amount of CO 2 which would warm the earth as much as that amount of that gas. Thus it provides a

The increase of CO2 was discussed in chapter 6, and the increases of CH4 and N2O will be discussed in chapters 11 and 10 respectively. Additional greenhouse gases produced by the chemical industry, such as CFC-11, have also accumulated in the atmosphere over the past decades and added to the greenhouse effect (Figure 7-1).

N2O (dikväveoxid, N2O) är en kraftig växthusgas och livslängden i atmosfären är ca källor till utsläpp av fluorkarboner, CFC eller svavelhexafluorid, SF6.
