Of course they do but NOAA is obviously aware of volcanoes and the rate of eruption . . . they still cannot explain the total increase in the aerosols and change in rate of global warming . . .
Well so you are finally at least admitting that there are natural sources for things like Sulfur Dioxide, debunking your original assertion. I am not quite even sure you know what it is you believe.
Interesting that Sulfur Dioxide is not even an aerosol, it is a gas. Are you alleging that planes full of sulfur dioxide gas are up there now?
