Your comment about our thin atmosphere gave me a thought.
Does all of the extra CO2 that folks say that
we humans are emitting “expand” our atmosphere?
There are processes that replenish the atmosphere else it would eventually be bled away by the solar wind. I’m not up on exactly how this happens. One could dive into the subject if curious enough. I’ve not looked at that myself. I just know that only 5 miles up you will die. I drive 3 times that to work each day.
Probably might thicken it a tiny bit.
