CLIMATE MATTERS

WORLD METEOROLOGICAL ORGANIZATION

GREENHOUSE GAS BULLETIN 2015

The World Meteorological Organization's Greenhouse Gas Bulletin is published annually to report on the latest trends in atmospheric concentrations of the most important long-lived greenhouse gases: carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). It also provides a summary of the contributions made by the other greenhouse gases that contribute to climate change. The Bulletin represents the consensus of a consortium of observation networks that have been in operation since the mid-1980s. The 2015 Bulletin is being released in advance of the Marrakesh climate conference (COP-22) to ensure that the talks have access to the most up-to-date scientific information available.
