WMO: Greenhouse Gases Level Reached Record High in 2011
World Meteorological Organization (WMO)
In its annual Greenhouse Gas Bulletin, WMO held that that the atmospheric volume of the greenhouse gases, which are often blamed for the change in atmosphere, reached a record high in 2011.
- As per the survey, the volume of carbon dioxide, the prime greenhouse gas grew at almost identical rate in previous 10 years (i.e. at an average by 2 ppm) and it touched 390.9 parts per million (ppm) or 40% above the pre-industrial level.
- The level of methane has also risen rapidly in the past 3 years.
- The Volume of Nitrous Oxide another greenhouse gas also increased in 2011. Nitrous Oxide has a long-term climatic impact which is 298 times larger than carbon dioxide.
