Deforestation Linked to Drier Amazon Rainforest and Increased Heat, New Study Finds

The Amazon rainforest has experienced increasingly dry seasons over the past several decades, and a recent study published in Nature Communications highlights a troubling connection between this trend and deforestation. The research reveals that around 75 percent of the decline in rainfall is directly attributed to the cutting down of trees, which also plays a role in the rising temperatures observed in the region. Since 1985, the hottest days in the Amazon have seen an increase of roughly 2 degrees Celsius, with 16 percent of that rise linked to tree loss.

Marco Franco, an assistant professor at the University of São Paulo and the lead researcher on the study, expressed his astonishment at the extent of the findings, noting that while deforestation was anticipated to be a contributing factor, the impact was more significant than expected. This information sheds light on the current state of the Amazon biome, which is often referred to as the planet's lungs due to its crucial role in regulating global climate by absorbing carbon dioxide. Unfortunately, decades of extensive logging and burning within the rainforest have altered this dynamic, leading some areas to become sources of greenhouse gas emissions instead of serving their original purpose.
