Abstract
There are a lot of satellites in low Earth orbit. We use them for things like communication and weather forecasting. Climate change is actually cooling this region of our atmosphere. This changes the density of air there. Changes in climate could impact these satellites. We wanted to know how much.
We used a model to estimate air density changes in low Earth orbit in the future. Then we calculated how many satellites the region could safely hold. We did this for three climate change scenarios. We found that by 2100, climate change could reduce the number of satellites low Earth orbit can hold by 50–66%. This means we need to develop strategies to make low Earth orbit a more sustainable resource for the future.
