Moerassen versnelde opwarming Aarde

"Massive peat bogs (=veen moeras) in Siberia and elsewhere may have helped spur global warming at the end of the last ice age some 12,000 years ago."

"But this does not take humans off the hook, given that the amount of methane sent into the atmosphere since the start of the Industrial Revolution is far higher than what occurred naturally from decomposing material in the old bogs"

"At the close of the last ice age, some 12,000 years ago, the bogs "really turned on," MacDonald said, and caused a rise in the atmosphere's methane level from 450 parts per billion by volume to 750 parts per billion. But from the year 1750 until the present, he said, methane levels went from 750 parts per billion to 1,700 parts per billion. About 60 percent of the methane going into the atmosphere is anthropogenic or human caused"

Voor de goede verstaander ook Methaan is een broeikas versterkend gas naast CO2.
