The sun's grand minimum

The sun has begun a periodic phase known as a grand minimum, when its magnetic strength stays much lower than normal for decades.  During previous grand minimums, weather patterns became abnormal with long periods of heat and cold occurring out of normal seasonal rotation.  Due to the physics associated with prolonged weak solar magnetic strength, large volcanic eruptions occur more frequently.  In the past, these have then caused much cooler temperatures across the globe for decades, even centuries.
