What's bad is each cool period since the Holocene Epoch (BC 5,500) is worse than the prior one. So when our Modern Warm Period is over (I predict in around 2 to 4 centuries) the next cool period will be even worse than the LIA.
About 25 years ago I read a huge book about the history of weather since Roman times. In the 1300s the weather in western Europe became cooler and MUCH more rainy. It rained so much that it was very difficult to get crops in the ground, people half starved all the time for decades. I figured this made them weak and more susceptible to the plague. But in the 1400s the weather became very nice and everyone had bumper crops for decades. Having so much food available allowed for migration from the farms to the cities, and hence the rise of a merchant class. And this resulted in extra funding for science and exploration in that century.
My concern is the next cool period may usher in the Big One, the descent into the next Ice Age. Glad I won’t live to see it.
