In particular, the Maunder minimum was a period of very low solar activity in the 17th century which contributed to the Little Ice Age. The drop in temperature impacted agricultural yields around the globe. [1]
That said, my professor would say that it's too early to infer much from this cycle's low sunspot number. The solar dynamo is very unpredictable in general, and quite possibly chaotic. Next cycle could be above average and that wouldn't shock anybody in solar physics.
