You don't hear to much about the role of sulfur dioxide in global warming but it wasn't until around 1980 that worldwide So2 levels were lowered to lessen acid rain. It is after this time global warming really started to ramp up. Then in 1991 Mount Pinatubo cooled the globe for several years and possibly more. I'm not sure I'm convinced of how little global cooling is caused by lessening in solar activity as we recently have been near a solar minimum. If coal burning and especially low sulfur coal continues it will help to increase global warming. China is a big player in that regard.
