Amazon rainforest degradation and climate risks

Overview

Scientists and researchers have warned that the destruction of the Amazon rainforest is threatening South America’s hydrological infrastructure. The forest facilitates a process described as ‘flying rivers,’ where trees release moisture into the atmosphere to create rainfall. Activities such as mining, deforestation, and fires are disrupting this connectivity, contributing to reduced rainfall, rising temperatures, and droughts in countries including Brazil, Bolivia, Colombia, and Ecuador. Data from 2026 indicates that the Amazon lost 2,053 km² of forest between January and August, a 2% increase compared to the same period in 2025. The majority of this loss occurred in the states of Pará, Mato Grosso, and Amazonas. While indigenous lands accounted for only 1.6% of the total loss, experts emphasize that protecting indigenous management is vital for forest resilience. Recent research published in Communications Earth & Environment indicates that climate extremes are increasingly affecting even well-preserved areas. While the southern ‘deforestation arc’ experiences the fastest warming, the most extreme climate shifts are occurring in the north-central region. Compounding these risks, the El Niño phenomenon is expected to intensify drought conditions through 2027. Following the first round of the Brazilian presidential election, environmental concerns have intensified. While the Lula administration saw deforestation decrease by 45 percent, reaching a decade-low, the election results show right-wing candidate Flávio Bolsonaro at 47 percent and incumbent Lula at 44.2 percent. Márcio Astrini, leader of the Climate Observatory, warned that a shift in power could lead Brazil toward a stance of “climate denial,” potentially reversing protections in favor of land exploitation for ranching and crops. In October 2026, satellite monitoring and field observations indicated an increase in fire outbreaks in the Amazonas region. Research from scientists in Brazil and the United Kingdom highlights a critical secondary impact: the formation of tropospheric ozone.

    Amazon rainforest future at risk amid Brazilian election results

    Climate experts warn that a potential victory for Flávio Bolsonaro in the Brazilian election could reverse recent significant reductions in Amazon deforestation achieved under Lula.

    Amazon rainforest faces increasing climate extremes and El Niño drought risks

    Climate extremes are hitting preserved areas of the Amazon, while the El Niño phenomenon threatens to extend droughts and fire risks in the region through 2027.

    Amazon rainforest faces deforestation and climate tipping point risks

    Amazon deforestation reached 2,053 km² from January to August 2026. Meanwhile, researchers warn the forest is nearing a tipping point that could transform it into a savanna and disrupt global climate stability.

    Amazon rainforest destruction threatens South American water cycles

    Amazon deforestation is disrupting the ‘flying rivers’ system, threatening South America's water supply and global climate stability as droughts impact regions from Brazil to Colombia and Ecuador.
