A new study warns that black carbon from kerosene fueled rockets is creating a significant climate footprint. These particles settle in the upper atmosphere, where they can alter Earth's temperature and mimic the effects of untested geoengineering. With the rise of satellite megaconstellations, researchers estimate that black carbon could account for over 40% of the space sector's climate impact by 2029. Experts are now calling for strict launch regulations to mitigate these environmental risks.
