WMO Greenhouse Gas Bulletin (GHG Bulletin) - No.16: The State of Greenhouse Gases in the Atmosphere Based on Global Observations through 2019
This Bulletin represents the latest analysis of observations from the WMO GAW Programme. It shows globally averaged surface mole fractions for carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) and compares them with the mole fractions during the previous year and with the preindustrial levels. It also provides insights on the change in radiative forcing by long-lived GHGs (LLGHGs) and contribution of individual gases to this increase.
Notes: The 2020 issue of the Bulletin focuses on the impact of COVID-19 lockdown measures on the levels of the greenhouse gases in the atmosphere.
