The measured increase of ocean acidity caused by atmospheric CO2 moving towards equilibrium with the oceans (and subsequently becoming carbonic acid) is indisputable especially when compared to measured atmospheric CO2 increases. Not to mention the fact that the isotopic ratio of atmospheric C12/C13 shows a trend towards increasing lighter carbon (from organic sources), as well.
But hey, it's easier to believe in hoaxes, I suppose
