Voyager’s original CMO was a Lieutenant Commander, which is presumably pretty typical for a ship of Voyager’s size. Bashir was commissioned as a Lieutenant Junior Grade to be the CMO on a backwater space station, so that’s presumably the bare minimum.
I would expect the Doctor’s first official rank (whatever that might be) to stick with him, plus promotion as appropriate. Adjusting it up and down based on posting would be a bizare thing to do for any other crewperson, and I’m sure The Doctor would object vigorously to such a thing.
It’s really depressing how any internet discussion about global warming is full of comments like this which only exist to downplay small but existent improvements that others have made. It’s whataboutism, plain and simple, and only serves to discourage people from doing anything at all.
This guy getting a more efficient stove isn’t going to save the planet, but at least it helps. Your comment (and many others in this thread) doesn’t do anything at all about our climate problem, and mostly serves to make other people feel stupid and inadequate for even trying to do something.
There is so much, so fucking much, that needs to be done to save our planet. If you think that political change is the only thing that will “really” matter to save the planet (it’s obviously going to be a huge factor), and you are so deeply committed to the ideal that the only things worth doing are those which directly further said political change, then you have serious work to do on your messaging strategy because what you had to say here clearly isn’t causing global change.
Alternately, if you think the situation is so impossible that nothing can be done to save it, go find a different void to yell into and stop trying to drag down those of us who still have some hope.
