Any one paying attention to Volcanos knows that they are blowing sky high all over the place.....Quiet sun causes the sun/earth magnetic interaction to allow more GCRs in to ground level. These add energy. Between lowest levels and highest levels, there is about a 20% variance, but this makes all the difference in the world.
The added energy nucleates clouds and "nucleates" volcanic gases.
I'll do the movie first.....when I can recreate it....sheesh....Office sucks!
