Greenhouse gas emissions hit record high levels ever

Melbourne, Nov 7 : Latest data from the World Meteorological Organisation (WMO) has shown that the amount of greenhouse gases in the atmosphere had reached record levels last year.

The UN's specialist weather agency said that the warming effect on the climate caused by heat-trapping gases in the atmosphere had increased by a third between 1990 and 2012, reported.

Carbon dioxide, mainly from fossil fuel-related emissions, accounted for 80 percent of that increase, though spikes in methane and nitrous oxide concentrations also played a part.

The agency also found the atmospheric carbon dioxide grew more quickly last year than its average increase over the past ten years, showing an accelerating trend.

Limiting the impacts of global warming would require sustained cuts to greenhouse gases, and the time for action was now, the WMO said in its latest Greenhouse Gas Bulletin.

CSIRO's Dr Pep Canadell said the WMO findings were further evidence of the unprecedented and relentless human impact on the planet.

It comes after the Intergovernmental Panel on Climate Change (IPCC) found that concentrations of heat-trapping gases in the atmosphere had hit levels not seen in at least 800,000 years.
