Deforestation in the Amazon rainforest is causing localized temperatures to rise by as much as 4°C (7.2°F) and reducing rainfall by 25 percent, according to a new study.
The findings highlight the significant impact of forest loss on regional climate patterns. The Amazon, the world’s largest tropical rainforest, plays a crucial role in regulating global weather systems and biodiversity, making its preservation a key concern for international environmental policy.
The study, details of which were not immediately available, focuses on the direct correlation between deforestation and changes in temperature and precipitation within the Amazon basin. The state of Amazonas, the largest in Brazil, is particularly affected. Located in the North Region of the country, Amazonas covers an area of 1,570,745.7 square kilometers and borders Colombia, Venezuela, Peru, Roraima, Pará, Mato Grosso, Rondônia, and Acre, according to Wikipedia.
Manaus, the capital of Amazonas, is situated at the confluence of the Negro and Amazon rivers, as noted by Britannica. The state’s population was estimated at 4,321,616 as of 2025.
The economic output of Amazonas reached R$ 131.531 billion (approximately US$24.4 billion) in recent reporting. The state’s Human Development Index (HDI) was recorded at 0.700 in 2021, classifying it as “high” on the development scale.
The increased temperatures and reduced rainfall linked to deforestation could have far-reaching consequences for the Amazon ecosystem and the communities that depend on it. The development underscores the urgency of addressing deforestation and promoting sustainable land management practices in the region.
