After years of warnings and growing fears among scientists “,frightening“Research on Wednesday revealed that climate change and deforestation they have turned parts of the Amazon basin, a crucial “sink”, into a source of carbon dioxide that warms the planet.
Although recent research has high concerns that the Amazon spews more CO2 and other greenhouse gases into the atmosphere than it absorbs, according to the new findings, published in the journal. Nature, They were presented as a “first” from scientists and climate reporters.
From 2010 to 2018, researchers in the new study, led by Luciana Gatti of Brazil’s National Institute for Space Research, performed “vertical profile measurements” of carbon dioxide and monoxide a few miles above the tree canopy in four sites in the Amazon.
The researchers found that “the southeastern Amazon, in particular, acts as a net source of carbon” and “total carbon emissions are higher in the eastern Amazon than in the western part.” The former, they noted, has been “subject to more deforestation, warming and water stress” than the latter in recent decades.
