Record wildfires devastated South America in 2024, raging out of control in biomes where fire is a natural part of the ecosystem, but also entering rainforests that had never burned before. Driven by expanding industrial agriculture, an El Niño episode, and droughts worsened by global climate change, the thick smoke from the wildfires grounded flights, shuttered schools, and caused lasting health problems. After favorable weather led to a reprieve from the most destructive fires worldwide last year, fire experts expect major wildfires to return to South America in 2026 and 2027. With fire season beginning in the continent, park rangers and firefighters hope that a trio of satellites launched in early July will provide more precise, rapidly updated data to wildland firefighters worldwide. The first three operational satellites from Earth Fire Alliance are meant to help improve global fire detection by providing frequent high-resolution wildfire data. These are part of the nonprofit’s FireSat program, which aims to deploy about 50 low-orbit satellites by 2030. The satellites are still being tested and calibrated, but in a few months, a first cohort of early adopters will gain access to the data. Once fully operational, the system could help fire agencies reduce emissions from wildfires worldwide by 5-10% yearly, according to Paul Bodnar, director of clean industry and special projects at the Bezos Earth Fund, which provided a $26 million grant to the program. The new satellites launch as the world enters an El Niño climate pattern that will likely mean drought and…This article was originally published on Mongabay
