Would reducing the amount of CO2 in the atmosphere reverse current problems? On it's own, it would start to, yes. It would reduce global temperatures, reduce weather irregularities, begin to cool the globe back down.
But we'd then have to move on to other things like deforestation, overfishing, water conflicts, plastics, etc. It's not a panacea, but it would reverse course on a pretty significant root cause.
