I was under the impression that carbon dioxide was largely a global problem. I don't have the knowledge to comment on that, or the other problems you brought up - in fact, I don't have much of an established opinion on the topic at all. I just wanted to present some math on how you could theoretically contribute to there being 62 times less CO2 in the atmosphere overall - if that's in your interests. I can't comment on the other intricacies (I'm not trying to be sarcastic or anything, I hope you understand what I'm trying to say.)
