It’s official. The Amazon has ‘flipped’ and now emits more carbon pollution than it soaks.
The dense rainforest that was long believed to be absorbing human-caused pollution, released nearly 20 per cent more carbon dioxide into the atmosphere over the last decade than it absorbed, according to a startling report in the journal “Nature Climate Change.”
While the world has been dealing with a virus that spreads unabated, researchers conducting the study found that between 2010 and 2019, Brazil’s Amazon basin released 16.6 billion tonnes of CO2, while soaking up only 13.9b tonnes.
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 the study’s 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.
The study also showed that deforestation — through fires and clear-cutting, which have proliferated under the rule of Brazilian President Jair Bolsonaro — increased nearly four-fold in 2019 compared to either of the two previous years, from about one million hectares (2.5 million acres) to 3.9 million hectares, an area the size of the Netherlands.
The Amazon basin, one of the planet’s richest ecosystems and home to thousands of indigenous peoples, suffered the worst blazes in a decade last year.
The region contains about half of the world's tropical rainforests, which are more effective at soaking up and storing carbon that other types of forests.
Another aspect of the research found for the first time that degraded forests were a more significant source of planet-warming CO2 emissions that outright deforestation.
Over the same 10-year period, from 2010 through 2019, degradation caused three times more emissions that outright destruction of forests, the researchers concluded.
Two C-130 Hercules aircraft carrying thousands of liters of water on Sunday began dousing fires devouring chunks of the world's largest rainforest.
The Amazon in South America is the largest, most diverse tropical rainforest on Earth and it is natural that the entire world is worried and angry over the worst blazes in years raging there. It is hugely important that the fires in the Brazilian rainforest, known as the lungs of the planet, be extinguished as quickly
Researchers found that the total forest loss between 2002 and 2019 was larger than the size of France, with more than half of the destruction happening in the Amazon region.
