Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Is that a thing? Meteors content matching Earths?
Meteors are leftovers of the same primordial stuff that made up earth, so a cross sample of them would largely share the same ratios as earth, minus the volatiles.
Though it looks like the community hive mind has made up its mind on this one
I did some very rough estimates and found that the amount of aluminum entering the Earth's atmosphere each year is probably between 100 and 500 tons, which would be roughly comparable to the amount coming from these LEO comm sats like Starlink.
These are just super ballpark figures, but it's in the same order of magnitude. More research is definitely necessary.
Logic would dictate that that is likely, though that statement itself isn't scientific. Do you have any sources to back that up? I could see a possibility where, perhaps, certain elements are more likely to coalesce into planetary bodies, and others into meteoroids. It could also depend on the location in the solar system where the formation occurred — the primordial dust cloud that made up the infant solar system, I would wager, would be far from uniform.
