"Draining huge African peatland a threat to climate: study" https://www.yahoo.com/news/draining-hug ... 30012.html
Extract: "A swampy forest in central Africa the size of England covers previously unknown carbon stocks equivalent to three years' worth of global CO2 emissions, scientists revealed Wednesday.
Draining these peatlands for agriculture, or reduced rainfall due to climate change, would release massive amounts of planet-warming greenhouse gases, they warned in a study published in Nature magazine.
"We found 30 billion tonnes of carbon that nobody knew was there," said Simon Lewis, co-lead author of the study and a professor at the University of Leeds.
"If the Congo Basin peatlands were to be destroyed, it would release billions of tonnes of CO2 into the atmosphere," he told AFP."
(such GHG sources are missing from AR5)
As if we didn't already have enough potential and already engaged carbon feedback loops!
