Satellites detected 9,045 fire hotspots in the Brazilian Amazon in the first half of October, 62% more than a year earlier, amid an El Niño-worsened drought. Deforestation over the past year fell to its lowest level since 1988.
Why it matters: The Amazon is a major carbon store, and both fires and clearing affect global climate goals.
Forest clearance in Brazil's Amazon fell about 42% year on year to roughly 3,335 square kilometres in the 12 months through July, one of the lowest totals since records began in 1988. Deforestation had expanded under former president Bolsonaro; the figures are a boost for Lula ahead of the run-off.
