The amount of greenhouse gases in the atmosphere reached a new high in 2010 since pre-industrial time and the rate of increase has accelerated, according to the World Meteorological Organization’s Greenhouse Gas Bulletin. It focussed special attention on rising nitrous oxide concentrations.
Between 1990 and 2010, according to the report, there was a 29% increase in radiative forcing – the warming effect on our climate system – from greenhouse gases. Carbon dioxide accounted for 80% of this increase.
“The atmospheric burden of greenhouse gases due to human activities has yet again reached record levels since pre-industrial time,” said WMO Secretary-General Michel Jarraud. “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.”
