Thanks for that great link which answers some of my questions.

Some worth pulling out -
So far this year, the equivalent of 228 megatonnes has been released, according to the Copernicus Atmosphere Monitoring Service. This is the highest level since 2010. ...

... there is a case to be made that some fire-adapted forests benefit from fires - they can help clear the forest and allow trees space to grow stronger.

But this is not the situation right now in the Amazon, says Yadvinder Malhi, Professor of Ecosystem Science at the University of Oxford. "These are fires that we are concerned about," he says. The humid forests of the Amazon have no adaptation to fire and suffer immense damage. Almost all fires in humid forests are started by people. ... "The forest takes around 20-40 years if it's allowed to regenerate," says Prof Malhi.

But any fires that are currently burning will leave the surviving trees more vulnerable to drought and repeated fires. ...

... the immediate effect of the fires will be on the climate of South America. Reduced rain fall is likely, leading to a more intensive dry season.

"The carbon emission could contribute to global warming," he adds, but the longer term global impact is "more difficult to pin down".

In the long-term, scientists have told the BBC the fires could make the Paris climate target more difficult to achieve. ...

... "It's hard to overstate the importance of these forests for indigenous peoples," he says. "They depend on them for food, medicines, clothing and a sense of identity and belonging.

But the incentives to steal these resources are high and "sadly it's not a question of one or two rogue actors", Mr Mazower says. He says this could be the "worst moment for the indigenous people of the Amazon" since the military dictatorship, which ended in the 1980s. ...
Great article. Thanks again for the link.
