WMO Greenhouse Gas Bulletin - No.9: The State of Greenhouse Gases in the Atmosphere Based on Global Observations through 2012

07 de noviembre de 2013

This ninth WMO/GAW Annual GHG Bulletin reports atmospheric abundances and rates of change of the most important long-lived greenhouse gases (LLGHGs) – carbon dioxide, methane, nitrous oxide – and provides a summary of the contributions of the other gases. These three together with CFC-12 and CFC-11 account for approximately 96%[4] of radiative forcing due to LLGHGs.
