# What effect will increased carbon dioxide concentrations in the atmosphere likely have on ocean acidity?

${\underbrace{C {O}_{2} \left(g\right) + {H}_{2} O \left(l\right)}}_{\text{carbonic acid}} r i g h t \le f t h a r p \infty n s H C {O}_{3}^{-} + {H}_{3} {O}^{+}$
i.e. ${H}_{2} O \cdot C {O}_{2} \equiv {\underbrace{{H}_{2} C {O}_{3}}}_{\text{carbonic acid}}$
