WMO Releases Greenhouse Gas Bulletin 2007
25 November 2008: The World Meteorological Organization (WMO) has released the 2007 Greenhouse Gas Bulletin, which indicates that the trend of rising emissions of greenhouse gases continued during that year.
The WMO Global Atmosphere Watch coordinates the measurement of these
gases in the atmosphere through a network of observatories located in
over 65 countries. The latest numbers show an increase of: 0.5% from
2006 for carbon dioxide; 0.25% from 2006 for nitrous oxide; and 0.34%
from 2003 for methane. The total warming effect of all long-lived
greenhouse gases was calculated to have increased by 1.06% from the
previous year and by 24.2% since 1990.
At the same time, levels of
chlorofluorocarbons continue to slowly decrease, a result of emission
reductions under the Montreal Protocol on Substances that Deplete the
