Sunspot activity has declined on schedule. February was an incredible month void of sunspots. This is clearly contributing to the extremely cold weather we are having. Cyclically, between 1645 and 1715, there was a prolonged collapse in sunspot activity known as the Maunder Minimum. Indeed, that was a period where sunspots all but disappeared. This coincided with the "Little Ice Age," which was a period from 1500 to 1850 in the northern hemisphere. It was so cold, Viking settlers even abandoned Greenland. I have stated many times that a major error in analysis is the attempt to reduce a problem to a single cause and effect. This topic of climate change is no different. Many scientists have strongly suggested that the Maunder Minimum caused the Little Ice Age. As I have shown, correlating everything that took place revealed that during solar minimum there is also an increase in volcanic activity and earthquakes. You will read that scientists seem to be debating between the two
