If not photons, then what?

I didn't read that particular answer but the sun has various cycles and I am no solar expert. When it is particularly active (energetic) the sun has lots of sunspots. The sunspots are obviously ociated with the sun's magnetism. Clearly, exactly how that interacts with our atmosphere, both photons (presumably not other radiation) and manetism, we don't understand. It may have feedbacks, positive and / or negative ones. The correlation has been known for quite a long time between sunspots and climate. Are you a denier of that correlation?
