Yes, I have been researching the Grand Solar Minimum extensively and agree with your comment:
"I stand by my guess that the current cooling cycle will cause food prices to increase 4 fold in 2 or 3 years which will trigger protests,panic and riots around the globe and that will put a controlled die-off plan into action."
I first extensively research the cooling cycle to become aware of its ramifications.
This spring into summer, the Boston area had much rain [diminished sun] and much cooler weather. The garlic was three weeks late for harvest. My normal practice is to plant pole beans in the harvested garlic beds for a second crop plus it adds nitrogen to the soil. Since I was running out of summer time, I had to plant bush beans rather than pole beans because the bush beans mature in 45 days versus 90 days for pole beans. However, pole beans growing on a trellis in more space and capturing more sun will yield ten times the bean bean crop that grow along the ground. To me, this is a similar situation indicating the effect of diminished sunlight.
In summary for planting and harvesting a garden, I have doubts about harvesting as much as in the past with a cooling period.
