CO2 also dissolves in water causing other problems.

yes but it's a natural process by photosynthesis (phytoplankton and algae). They emit O2 as well.

unfortunately the acid increase due to CO2 is quicker destructive than natural processes by photosynthesis can compensate see https://www.gbrmpa.gov.au/our-work/threats-to-the-reef/climate-change/ocean-acidification

True through sublimation as well co2 would be dissolved into seawater. Still with such a very large quantity of co2 being emitted doesn't it affect the pressure. Just curious though!

I suppose the atmosphere is not constrained like a bottle wall so just increasing the amount of gas would maybe not follow directly Boyle's law even if there was not chemical and biological interaction going on. It is an interesting question. There is a similar question only the volume of the PVT is considered here: https://earthscience.stackexchange.com/questions/14489/is-volume-of-air-increasing-as-co2-levels-increase?rq=1

Short and correct answer (apart from everything else in this thread): The amount of CO2 released into the atmosphere is insignificant for the total atmospheric mass, but not negligible for its infrared opacity (CO2 has a very high infrared opacity per unit mass compared to the average atmosphere).

How does atmospheric pressure remains constant even though we have released 43 billion tons of $\ce{CO2}$ in one year?

(Asked by: username_0 on 2021-11-01)

I've heard that the concentration of CO2 has been increased in the air.

It should have increased atmospheric pressure, right?
