Buddy boy, on the subject of this post, SO2 in the atmosphere, I showed what a liar your are. Posted a definative article that showed that mankind puts up more SO2 in normal years, than all the volcanos. And even when we get a Pinatubo, we still exceed the volcanoes.
Sulfur dioxide (SO2) - Air quality fact sheet
What is sulfur dioxide?
Sulfur dioxide is a gas. It is invisible and has a nasty, sharp smell. It reacts easily with other substances to form harmful compounds, such as sulfuric acid, sulfurous acid and sulfate particles.
About 99% of the sulfur dioxide in air comes from human sources. The main source of sulfur dioxide in the air is industrial activity that processes materials that contain sulfur, eg the generation of electricity from coal, oil or gas that contains sulfur. Some mineral ores also contain sulfur, and sulfur dioxide is released when they are processed. In addition, industrial activities that burn fossil fuels containing sulfur can be important sources of sulfur dioxide.
Sulfur dioxide is also present in motor vehicle emissions, as the result of fuel combustion. In the past, motor vehicle exhaust was an important, but not the main, source of sulfur dioxide in air. However, this is no longer the case
