That just puts you on the same LEVEL that 'they' are.
They are 'theorizing' because they don't really know either. Nothing listed in the article explained what caused this departure from the normal cycles.
The 'plasma slows down, then it speeds up' theory causes more questions than it gives answers.
Until they can plant PLASMA FLOW MARKER BUOYS on the surface (or inside) of the Sun, it is really difficult to tell if the plasma changes speed at all.
I nominate the crack Algore climate team to plant those plasma flow marker buoys (in person).
