Summary:
- Greenhouse gas emissions are causing the Earth's atmosphere to expand, which is leading to increased drag on space debris, causing it to fall back to Earth more quickly.
- This could lead to a significant increase in the amount of space junk re-entering the atmosphere, posing a risk to satellites, spacecraft, and even people on the ground.
- Scientists warn that urgent action is needed to mitigate the growing problem of space debris, which could become unmanageable if greenhouse gas emissions continue to rise.
