"Bristol University researchers say a previously unexplained surge of carbon dioxide levels in the atmosphere in recent years is due to more greenhouse gas escaping from trees, plants and soils. Global warming was making vegetation less able to absorb the carbon pollution pumped out by human activity...Measurements of carbon dioxide in samples of air show a sharp increase since the turn of the century, with unusually high levels in four of the past five years. The spike does not seem to match the pattern of increased emissions from fossil fuel burning, and can only be partly explained by natural events such as fires and weather phenomena including El Niño." The money quote offered by the researchers:- The findings represent an "unusually strong out-gasing of CO2 of the terrestrial biosphere." Is it a knock out blow? Waiting on round two.

UPDATE:- "The rampant slashing and burning of tropical forests is second only to the energy sector as a source of greenhouses gases according to report published today by the Oxford-based Global Canopy Programme, an alliance of leading rainforest scientists. Figures from the GCP, summarising the latest findings from the United Nations, and building on estimates contained in the Stern Report, show deforestation accounts for up to 25 per cent of global emissions of heat-trapping gases, while transport and industry account for 14 per cent each; and aviation makes up only 3 per cent of the total."
