What we have here is a lack of Sunspots
Sunspot formation is triggered by a magnetic field, which scientists say is steadily declining. They predict that by 2020 there may be no remaining sunspots, and the sun may stay spotless for several decades.
The last time the sunspots disappeared altogether was in the 17th and 18th century, and coincided with a lengthy cool period on the planet known as the Little Ice Age....and lasted 400 years.

As to the cooling in the “little ice age” it was nothing like the real ice age.
During the actual ice age ocean levels were 100 feet or more below today's level.
