The tarnishing of silver is due to the reaction of the silver ware with sulphur compounds in the atmosphere. The reason for the enhancement for the tarnishing is due to an increase rate of pollution that has lead to higher amounts of sulphur in the atmosphere.

Tarnishing of silver is due to hydrogen sulphide gas which is released due to pollution.
4Ag + O2 + 2H2S → 2Ag2S + 2H2O
so because of pollution which is more now days , we see silver articles getting tarnished(black coating).
