When exposed to acidic precipation;marble will begin to erode and the color will change.To try and stop this ,use compresses of 10 precent solution of anmonia.Press on the statue;you want to bring back a color balance.And if that doesn't work entirely,combine the anmonia work and a micro sandblaster.Between the two you can get a good color;ten wash with soap and water.Rinse and let dry;then you apply a uv-sealant,that will protect it from the elements.It should be checked every 6 months,or so ,if the sealant protects against;oil and grease also .That will be even better for the marble.Thats why many people use copper forms,and put a marble texture on the outside,and it's easier to look after.
The fastest weathering process affecting both limestone and marble (because they are both calcium carbonate) is acid rain. Nitric acid rain is produced from car exhaust generated smog. Sulphuric acid rain is produced from industries burning coal as well as volcanic eruptions.
Marble is more sensible.
I suppose that a marble statue is more sensible (excepting wood statues).

Chemical weathering will have dissolved some of the calcite of which the statue is composed, as well as acid rain having caused erosion, if there is acid rain occurring in the area.
the statue of david is carved from carrara marble

Marble is attacked by carbonic acid - carbon dioxide dissolved in water. The desert has little rainfall so chemical weathering occurs at a very slow rate.
