The Greenhouse Gases Bulletin produced annually by the World Meteorological Organization (WMO) reveals that in 2010 a new record was reached in the concentrations of these elements in the atmosphere.
According to the report, between 1990 and 2010 warming increased by 29 percent, and this was caused mainly by carbon dioxide, and to a lesser extent by other gases such as methane and nitrogen oxide. The concentrations of these compounds have not stopped rising since pre-industrial times, and according to Michel Jarraud, Secretary General of the WMO: "even if we manage to stop the emissions of greenhouse gases today – and this case is far from the reality – they would remain in the atmosphere for decades and would continue to affect the delicate balance of our climate, of our living planet. "
On the other hand, the report also contains some more optimistic data, since it has been found that, as a result of the campaign to protect the ozone layer on Earth, the concentration of chlorofluorocarbon gases (CFCs) has decreased in recent years.
