December passed without a trace of snow. All the forecasts still have no snow in sight. Is it likely NYC will have a snowless winter?

Carbon dioxide mixes with rain water and forms carbonic acid. Dust containing nitrates (or auto exhaust) mixes with rain and makes nitric acid. Any source of sulfate (usually pollution) forms sulphuric acid.

Acid rain is a natural product and it dissolves limestone rocks. Like this: https://www.google.com/search?newwindow=... A mixture of nitric and sulphuric acids is called aqua regia and it dissolves gold. A small amount of acid dissolves enough gold to be a problem for miners trying to get the gold.

There are cities with limestone buildings where acid rain is washing the buildings away. Venice, Italy is one.

Acid rain comes from the atmosphere. When there is pollution, acid forms and it comes down in the form of precipitation.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
