Trees are biggest methane ‘vents’ in wetland areas – even when they’re dry

For climate obsessives and modellers convinced of the claimed effects of ‘important greenhouse gases’ (to quote the reporter), this must be a bit of a setback.

Most of the methane gas emitted from Amazon wetlands regions is vented into the atmosphere via tree root systems—with significant emissions occurring even when the ground is not flooded, say researchers at the University of Birmingham.

In a study published in the Philosophical Transactions of the Royal Society A, the researchers have found evidence that far more methane is emitted by trees growing on floodplains in the Amazon basin than by soil or surface water and this occurs in both wet and dry conditions, reports Phys.org.

Methane is the second most important greenhouse gas [Talkshop comment – excluding the main one by far: water vapour] and much of our atmospheric methane comes from wetlands.

A great deal of research is being carried on into exactly how much methane is emitted via this route, but models typically assume that the gas is only produced when the ground is completely flooded and underwater.

In wetland areas where there are no trees, methane would typically be consumed by the soil on its way to the surface, but in forested wetland areas, the researchers say the tree roots could be acting as a transport system for the gas, up to the surface where it vents into the atmosphere from the tree trunks.

Methane is able to escape via this route even when it is produced in soil and water that is several meters below ground level.

This would mean that existing models could be significantly underestimating the likely extent of methane emissions in wetland areas such as the Amazon basin.

    Methane from wetlands is not new but has been going on since long before humans trod the earth. Suddenly it is a danger to all life on the planet? These clowns need to seek help for their modelling addiction….

    Methane paranoia in Ireland…

    ‘in collaboration with colleagues at University College Dublin’

    Was every freshmen required to go test cattle? Is hazing allowed in Ireland?

    The solution is simple (for Greens). Chop down all the trees. Then replant them to “fight climate change”. Then chop them down again to supply fuel for electricity generation (when the wind doesn’t blow).

    Science rediscovers ‘will-o’-the-wisp’. How not very academic of them!

    Have the warmists admitted they know nothing, yet?
