Too many visitors for the Sistine Chapel

The Sistine Chapel has too many visitors, and there could be problems for the frescoes,  due to powders, carbon dioxide  and temperature; therefore, the Ecclesiastic Directorate could probably decide to limit the number of visitors admitted at the same time. Anyway, this is only a pessimistic forecast…since, for the time being, the Vatican Museums Authority has charged a specific firm of planning a new dedicated air-conditioning system.
