WMO Reports Highlights Increase Climate impacts of GHGs
6 November 2013: The World Meteorological Organization (WMO) has published its annual Greenhouse Gas Bulletin, reporting that between 1990 and 2012, the warming effect on the climate has increased by 32% because of carbon dioxide and other greenhouse gases (GHGs).
The Bulletin outlines the growth in GHGs over the last few years, as well as their contribution to radiative forcing (the warming effect on the climate). It highlights that the levels of carbon dioxide, methane and nitrous oxide in the atmosphere reached record highs in 2012, and is still increasing. According to WMO, the effects of this will continue to be felt for hundreds and thousands of years.
Commenting on the Bulletin, WMO Secretary-General Michel Jarraud underlined that the observations show “how heat-trapping gases from human activities have upset the natural balance of our atmosphere and are a major contribution to climate change.” He added that, “Limiting climate change will require large and sustained reductions of greenhouse gas emissions.” [Publication: 2013 WMO GHG Bulletin] [WMO Press Release] [UN News Release]
