The World Meteorological Organization (WMO) has published its annual Greenhouse Gas Bulletin on 9 September 2014. The bulletin reports on atmospheric concentrations of greenhouse gases remaining in the atmosphere after the emitted gases go through a complex system of interactions between the atmosphere, the terrestrial biosphere and the ocean. For the first time, the bulletin includes data on ocean acidification of the seas caused by carbon dioxide. IOCCP leaders, Toste Tanhua (IOCCP Chair), Laura Lorenzoni (IOCCP expert for time series observations) and Masao Ishii (IOCCP expert for ocean interior observations) co-authored the OA section with colleagues from IAEA.
The Bulletin attracted significant media attention worldwide. The original WMO press release can be accessed here.
