Which outcome occurs when elevated atmospheric CO₂ levels persist?

💡 Explanation

Increased atmospheric CO₂ dissolves in rainwater and enhances carbonic acid weathering; this acid reacts with limestone, accelerating dissolution within karst landscapes in the form of widened joints and sinkholes. Therefore, dissolution increases, rather than other geological processes, because of the specific reaction.
