Which outcome arises from increased atmospheric carbon loading onto limestone?

💡 Explanation

Higher CO2 drives carbonic acid production, accelerating chemical weathering from dissolution; therefore karst formation increases, rather than decreased weathering or direct metamorphic change, because the chemical equilibrium of limestone favors dissolution in acidic conditions.
