From what I’ve read, most climate scientists regard the effect of these cycles of sunspots & solar winds as very small, basically a blip compared to the larger warming trend that coincides with the industrial revolution. And the effects of these solar cycles on climate have been studied for many many years.
Even the article you link to claims a maximum effect of half a degree (which is I think, higher than most scientists would grant) and it further states, “this reduction in temperature is significant, even though it will do little to compensate for human-induced climate change.”
