Yes, sun spots cause increased UV emissions, which increase the heat from the sun (actually beats back cosmic rays). The maunder minimum will continue thru 2020, at least. Look for poor wine production in Germany and north France. Also, New York.
In their desperation, the warmists are putting the blame on pollution from China for the reason the Earth's temperature hasn't increase over the last decade.
In short, more beer production in Germany and less wine. Don't throw away the overcoats!
