The growing number of satellite launches and re-entries poses significant environmental risks. High-altitude black carbon emissions can warm the upper atmosphere, while aluminum oxides from re-entries may deplete the ozone layer. These pollutants could lead to unpredictable changes in weather patterns, including altered rainfall and droughts. The study estimates that by 2029, pollution from satellite megaconstellations will account for over 40% of the space sector's total emissions. Without regulation, the accumulation of these pollutants could reach levels that impact Earth's climate, creating unintended and potentially severe consequences.
