Three different teams of scientist studying the sun have concluded that the sun is entering a quiet period that may replicate a Dalton Minimum, or even a Maunder Minimum. Details here.
These Grand Minimums resulted in cooler temperature on the earth. Each of these cool periods had social and economic impacts, shared by millions across the globe. We can learn from these past events. It was Sir William Herschel who noted the relationship between the sun and the weather when he discovered a correlation between sunspots and wheat prices in the early 1800s. When the sun was quiet, the price of wheat went up, when the sun was active the price of wheat went down.
