SNIP: A surprising scientific study released Thursday presents troubling news about the enormous forests of the planet’s tropical midsection — suggesting that they are releasing hundreds of millions of tons of carbon to the atmosphere, rather than storing it in the trunks of trees and other vegetation.
“The losses due to deforestation and degradation are actually emitting more CO2 to the atmosphere, compared with how much the existing forest is able to absorb,” said Alessandro Baccini, the lead author of the study and a researcher at the Woods Hole Research Center.
Specifically, the study found that tropical forests are losing 425 million tons of carbon annually, on average, which is the net result after you sum up 861 million tons of losses and 436 million tons of gains as forests grow each year.
“Forests are losing more carbon than we thought,” Baccini said. “And one reason they’re losing so much carbon is because there is actually a lot of disturbance in the forest. You don’t have to wait for deforestation. You don’t have to only look for places that completely lost the trees.”
This is a far greater loss than previously thought and carries extra force because the data emerges from the most detailed examination of the topic ever undertaken. The authors say their findings – published in the journal Science on Thursday – should galvanise policymakers to take remedial action.
