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. In table 1 the main characteristics of LLGHGs are listed in terms of Global Radiative Forcing in W.m-2, Global Warming Potential GWP 100 (time horizon of 100 years), Atmospheric lifetimes in years and relative importance in %. 2012-01-16 · Aside from water vapour, the four principal greenhouse gasesare carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and the halocarbons or CFCs (gases containing fluorine, chlorine and Year Month MEI CO2 CH4 N2O CFC-11 1983 5 2.556 345.96 1638.59 303.677 191.324 1983 6 2.167 345.52 1633.71 303.746 192.057 1983 7 1.741 344.15 1633.22 303.795 192.818 1983 8 1.13 342.25 1631.35 303.839 193.602 1983 9 0.428 340.17 1648.4 303.901 194.392 1983 10 0.002 340.3 1663.79 303.97 195.171 1983 11-0.176 341.53 1658.23 304.032 195.921 1983 12-0.176 343.07 1654.31 304.082 196.609 1984 1-0.339 344.05 1658.98 304.13 197.219 1984 2-0.565 344.77 1656.48 304.194 197.759 1984 3 0.131 345.46 1655 84 x – methane (CH 4) – I.e.

Carbon dioxide (0.04%), nitrous oxide, methane, and ozone are trace gases that account for almost 0.1% of Earth's atmosphere and have an appreciable greenhouse effect.

(a) CFC > N2O > CO2 > CH4 (b) CFC > CO2 > N2O > CH 4 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).
