No Let Up in Greenhouse Gas Rise
Published: 21 Nov 2011
Concentrations of greenhouse gases in the atmosphere rose to yet another high in 2010, according to the UN's weather agency.
Levels of carbon dioxide (CO2) - the major contributor to climate change - rose by 2.3 parts per million between 2009 and 2010.
That exceeds the average for the past decade of 2.0 parts per million, the World Meteorological Organization says.
The latest round of UN climate talks begin in South Africa in two weeks.
"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.
The gas that is of greatest concern to policy makers looking to stem human-induced climate change is CO2.
