Climate change may affect the number of satellites we can host in low Earth orbit 

As CO₂ levels rise, they cause the thermosphere to cool and contract. This leads to lower atmospheric density in low Earth orbit, where most satellites operate

Lower density means less drag, so space debris stays in orbit longer, increasing  the risk of collisions

Continued emissions could reduce the carrying capacity of LEO by up to 66% by 2100, meaning fewer satellites can be safely maintained without triggering runaway debris growth (Kessler Syndrome)
