Which risk increases when CO2 levels rise within karst cave systems?

💡 Explanation

Increased CO2 concentrations enhance carbonic acid formation and accelerate chemical weathering; dissolution occurs because carbonate bedrock reacts with carbonic acid via *carbonation*, therefore the risk increases, rather than reduced rock dissolution rates that reduced CO2 levels promote.
