Carbon dioxide rose 0.5% from 2006 to reach 383.1 parts per million, while nitrous oxide levels were up 0.25%, according to latest WMO statistics.

Methane meanwhile increased 0.34%, surpassing the highest level recorded in 2003.

"Using the NOAA Annual greenhouse gas index, the total warming effect of all long-lived greenhouse gases was calculated to have increased by 1.06% from the previous year and by 24.2% since 1990," said the WMO.
