Yes, increased CO2 probably contributes. I'm guessing it's a drop in the bucket for ocean currents though. Mining salt and dumping it on roads is probably an issue to, as it runs off and goes down rivers. Again, not doing much because the oceans are so big. But over a million years maybe not so great to do.
