Also oxygen depletion is obvious result of co2 going up seeing as it's air where the oxygen is coming from for those molecules. Unlike co2 though it's not such a big deal, mostly because there's a lot of oxygen so losing bit doesn't matter much and because we will run out of carbon in fossil fuels long before we run out of oxygen in the air. Basically oxygen levels won't be a problem but yes oxygen levels are going down.
