Acid rain!
Sulfur dioxide gas reacts with water droplets in the air to form sulfurous acid, which is sometimes oxidized to sulfuric acid by oxygen in the air.
Sulfur dioxide reacts with droplets of airborne water to form 'Acid Rain'. Oddly, acid rain has been found to decrease the amount of greenhouse gases in Earth's atmosphere. So, it can be said with some truth that the great reduction in acid rain in the US since the '70s may have resulted in a warmer climate, incorrectly called global warming.
Sulfur dioxide gas is produced when sulfur reacts with oxygen.

No, sulfur dioxide is not amphoteric. It is a acidic oxide that reacts with water to form sulfurous acid.
"oxidation"
No. Sulfur dioxide is a compound, which makes it a pure substance, not a mixture.
When sulfur is burning, it reacts with oxygen to form sulfur dioxide. The chemical formula for sulfur dioxide is SO2.
Sulfur dioxide reacts with moisture in clouds to form sulfuric acid, which can contribute to acid rain. This reaction occurs when sulfur dioxide dissolves in water droplets in the atmosphere, leading to the formation of sulfuric acid.
Limestone is typically added in the final stages to remove sulfur from coal during a process called flue-gas desulfurization. Limestone reacts with sulfur dioxide to form calcium sulfate, which can then be easily removed.
The equation for the formation of sulfur dioxide in an engine is SO2 = S + O2. When sulfur-containing fuel (such as diesel containing sulfur) is burned in the engine, sulfur reacts with oxygen in the air to form sulfur dioxide.
When an oxide reacts with sulfur dioxide, it can form a sulfate. The sulfur dioxide can oxidize the metal in the oxide, resulting in the formation of a metal sulfate compound. This reaction is often used in industrial processes to remove sulfur dioxide emissions from flue gases.
