Air quality monitoring shows rise in greenhouse gases

A report released by the World Meteorological Organisation (WMO) has revealed that levels of greenhouse gases have continued to increase.

Concentrations of carbon dioxide, methane and nitrous oxide have reached the highest levels recorded since 1750 - before the industrial revolution would have had an impact.

Recent analysis has demonstrated that the averaged mixing ratio of carbon dioxide in the atmosphere increased by two parts per million (ppm) in 2008, up from overall levels of 383.2 ppm the previous year.

The WMO noted that this continued the tendency of exponential increase.

Michael Jarraud, secretary general of the organisation, said that the latest findings indicate that the rate of increase in greenhouse gas levels is quickening.

He issued a stark warning to world leaders due to attend the UN's summit on climate change in the Danish capital next month, commenting: "This reinforces the fact that action has to be taken as soon as possible.

"We are looking to Copenhagen to come up with a strong decision on greenhouse gases. The more we delay the decision, the bigger the impact will be."

Politicians are preparing to discuss emissions cuts at the talks in Copenhagen from December 7th to 18th, when it is hoped that global targets on greenhouse gas reduction can be agreed.
