Greenhouse gases reach new high, says UN meteorological report
The presence of greenhouse gases in the Earth’s atmosphere last year reached its highest levels since pre-industrial times, a report released by the United Nations World Meteorological Organization (WMO) warns today.
The latest edition of WMO’s Greenhouse Gas Bulletin, which places special focus on rising nitrous oxide concentrations, also notes that the rate of increase of greenhouse gases has recently accelerated.
“Even if we managed to halt our greenhouse gas emissions today - and this is far from the case - they would continue to linger in the atmosphere for decades to come and so continue to affect the delicate balance of our living planet and our climate,” said WMO Secretary-General Michel Jarraud.
According to the report, the 20 years to 2010 saw a 29 per cent increase in “radiative forcing” - the warming effect the gases have on the Earth’s climate - from greenhouse gases, with carbon dioxide accounting for 80 per cent of this increase.
