A study published in the journal Nature Climate Change points out that humanity can no longer depend on the Amazon to help absorb the pollution carbon dioxide produced by man. All because, according to the survey, from 2010 to 2019, the largest rainforest in the world emitted 16,6 billion tons of CO², while removing only 13,9 billion tons.
“We kind of expected it, but this is the first time that we have figures showing that the Amazon Brazilian changed and is now a net issuer. We do not know at what point the change may become irreversible ”, told AFP the scientist from the National Institute of Agronomy and Research in France (INRA) and co-author of the study, Jean-Pierre Wigneron.

According to the survey of researchers, the deforestation in the region increased almost fourfold in 2019 compared to any of the previous two years. From about one million hectares it went to 3,9 million hectares, an area the size of the Netherlands. Fires are the main reasons for deforestation.
In a statement, the National Institute of Agronomy and Research in France states that "Brazil has seen a sharp decline in the application of environmental protection policies after the change of government in 2019".
About 60% of the Amazon rainforest is in Brazil. “The Amazon basin as a whole is probably neutral (in carbon). But in other countries with Amazon rainforest, deforestation is also increasing and the drought has become more intense ”, warned Wigneron.
Amazon is one of the “tipping points” in the climate system
In 2019, CO² emissions reached 40 billion tons worldwide. The Amazon is very important to try to contain this increase.
To give you an idea, over the last half century, plants and soil have consistently absorbed about 30% of these emissions, even when those emissions have increased by 50% in the period. The oceans also helped, absorbing more than 20%.
