Record dryness in the Amazon caused by climate change

Climate change is wreaking havoc on one of our planet’s most important defenses against global warming. A recent study found that it was the primary cause of the worst drought to hit the Amazon rainforest in at least 50 years. The Amazon is frequently referred to as the “lungs of the planet” since it is essential in absorbing carbon dioxide that warms the earth. However, the quick destruction of forests has made it more susceptible to harsh weather. Although droughts occur frequently in the Amazon, the researchers describe the one that occurred last year as “exceptional”.

One of the biggest rivers in the world, the Rio Negro, surpassed records dating back more than a century in October when it dropped to its lowest point ever observed close to Manaus, Brazil. The Amazon is not just a haven against climate change but also a rich source of biodiversity, home to about 10% of all species on Earth and many more that have not yet been found. Millions of people who depend on rivers for transportation, food, and money have been directly harmed by the drought, which has upset ecosystems and disproportionately affected the most disadvantaged.

El NiƱo, a natural weather pattern in which sea surface temperatures rise in the East Pacific Ocean, is one cause of these dry circumstances. Rainfall patterns around the world are impacted by this, especially in South America. However, the World Weather Attribution group claims that the primary cause of the severe drought was climate change brought on by humans, which reduced soil water content in two major ways. First off, when the climate warms, the Amazon usually receives less rainfall than it did during the drier months of June through November. Second, higher temperatures cause more evaporation from the soil and plants, which results in increased water loss.
