WMO Greenhouse Gas Bulletins
WMO Greenhouse Gas Bulletin
The Atmospheric Environment and Research Division of WMO’s Research Department publishes the WMO-GAW Annual Greenhouse Gas Bulletins. Each year, these bulletins will report the latest trends and atmospheric burdens of the most influential, long-lived greenhouse gases; carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), as well as a summary of the contributions of the lesser gases. The Bulletins represent the consensus of a consortium of networks operated since the mid 1980s. These three major gases alone contribute about 88% of the increase in radiative forcing of the atmosphere by changes in long-lived greenhouse gases occurring since the beginning of the industrial age (since 1750).
