The Amazon rainforest now emits more carbon than it absorbs
recent Learn “Nature” magazine shows that the Amazon rainforest now emits more carbon dioxide than it absorbs.Scientists have confirmed for the first time that even though it was once the largest Carbon sink Around the world, rain forests have become pollutants due to the high rate of deforestation.

According to this study, forests emit approximately 1 billion tons of carbon each year.The study has determined that forest fires are one of the main causes of fires EmissionsMost of the fires are deliberately starting to clear the woodland for beef and soybean planting. Since most of the world’s soybean supply is produced in Brazil, environmentalists have called for a global dialogue on the status quo of Amazon.
Researchers use small aircraft to measure carbon dioxide Above the Amazon, up to 4,500 meters above the canopy. The research started in 2010 and continued until 2018. Previous research was conducted through satellite images, but the accuracy was low.
The research was led and co-authored by Luciana Gatti of the National Institute of Space Research in the United States. BrazilCommenting on the results of the survey, Gatti said that deforestation alone will turn forests into sources of carbon emissions. Even in areas without forest fires, the researchers found that in areas with severe deforestation, carbon emissions are higher than carbon absorption.
“The first very bad news is that the carbon dioxide produced by forest burning is about three times that of forests. The second bad news is those places deforestation 30% or more indicates that carbon emissions are 10 times higher than if the deforestation rate is less than 20%,” Gatti said.
Researchers participated in the inspection of more than 600 vertical profiles of CO2 and carbon monoxide.The study found that fires alone produce 1.5 billion tons of carbon dioxide in a year, and forest Growth only removes about 5 billion tons of carbon dioxide each year. As the Guardian reported, “The remaining 1 billion tons in the atmosphere is equivalent to the annual emissions of Japan, the world’s fifth-largest polluter.”
Professor Simon Lewis of University College London praised the research, saying: “Flying once every two weeks and maintaining consistent laboratory measurements for nine years is an amazing feat.”
In light of this news, Brazilian President Jal Bolsonaro has been under scrutiny for supporting farmers to expropriate land in the forest, leading to deforestation.If this situation continues, some countries Europe Threatened to block the EU’s trade agreement with Brazil.
