Trees, woodlands and methane

Methane might be a clean fossil fuel when in a pipeline but it is second only to carbon dioxide in terms of contributing to global warming, when present in the atmosphere. Over the last two centuries, the level of methane in the atmosphere has increased dramatically (and now stands at approximately 1800 parts per billion). Much of this increase has been linked to certain agricultural practices (farming of cattle and other ruminants, paddy fields) plus the emissions from decomposing landfill etc.
However, recent work in a number of forested and woodland areas (for example, The Amazon, Borneo, China, Hungary etc) has suggested that the release of methane by trees is significant, and given that methane is an extremely potent greenhouse gas - this has to be considered in relation to climate change. The methane contribution from trees has not really been considered when working out the global methane budget but it now seems that they make a contribution. Read more...
