Author(s) : WMO (World Meteorological Organization)

Type of article: Article

Summary

The latest analysis of observations from the WMO Global Atmosphere Watch Programme shows that the globally averaged mixing ratios of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) reached new highs in 2009, with CO2 at 386.8 ppm, CH4 at 1803 ppb and N2O at 322.5 ppb. These values are greater than those in pre-industrial times (before 1750) by 38, 158 and 19%, respectively.See also this Bulletin, references 2010-2075 to 2077 and 2079 to 2080.
