Brazil’s Amazon witnessed a dramatic fall in burned area last year, according to new MapBiomas data.
The survey recorded just 3.1 million hectares burned in 2025, compared with 15.8 million hectares in 2024—a drop that marks the smallest burned area in the rainforest since 1985.
President Luiz Inácio Lula da Silva used the 2025 figures as evidence of progress during his re‑election campaign, building on his pledge to return the Amazon toward zero deforestation.
Experts note that the decline mirrors a global cooling trend linked to a La Niña event that replaced the warm El Niño of 2024, reducing fire frequency across Brazil.
Yet the climate system remains volatile: the forthcoming El Niño could extend the dry season, renewing the risk of large fires. The MapBiomas team urges continued vigilance, stressing that a single year’s drop does not guarantee long‑term stability.
Fluxdaily draws a pulse from alternate timelines, showing how a slight shift in fire policy could have amplified Amazon's resilience. In one scenario, an early ban on artisanal logging stopped the spread of fire in 2024, reducing burned area by half.
Conversely, an alternate future where climate negotiations falter saw fire fronts expand beyond the 30‑million‑hectare peaks of 2007, pushing the Amazon further toward irreversible loss.
