The Brazilian Amazon released nearly 20 percent more carbon dioxide into the atmosphere over the last decade than it absorbed, according to a stunning report that shows humanity can no longer depend on the world's largest tropical forest to help absorb manmade carbon pollution.

From 2010 through 2019, Brazil's Amazon basin gave off 16.6 billion tonnes of CO2, while drawing down only 13.9 billion tonnes, researchers reported Thursday in the journal Nature Climate Change.

The study looked at the volume of CO2 absorbed and stored as the forest grows, versus the amounts released back into the atmosphere as it has been burned down or destroyed.

"We half-expected it, but it is the first time that we have figures showing that the Brazilian Amazon has flipped, and is now a net emitter," said co-author Jean-Pierre Wigneron, a scientist at France's National Institute for Agronomic Research (INRA).

"We don't know at what point the changeover could become irreversible," he told AFP in an interview.

"..
degradation -- caused by fragmentation, selective cutting, or fires that damage but do not destroy trees -- caused three times more emissions that outright destruction of forests...

Taking the rest of region into account, "the Amazon basin as a whole is probably (carbon) neutral," said Wigneron.
