But since mankind has walked the earth only about 150K years, I try to make our conservative arguments within that timeframe. And we have a decent amount of recorded history from the past few thousand years of what life was like within the micro warm and cool periods.
There's also the issue of many different people groups committing most atrocities in history during the cooling periods. For example, it was in the Little Ice Age that 300-400K black were brought as slaves to the United States, 1 to 1.2 million whites were taken as slaves to the North African states, 5 to 5.5 million blacks were brought as slaves to the Spanish speaking nations in America, and 10-12 million blacks were taken as slaves to Asia. (Yeah, I listed those numbers in part to show how the one part of slavery most talked about is the smallest one by number. LOL). Also, the 60K or so indigenous Americans forced out in the Trail of Tears happened at about the coldest point of the Little Ice Age. Likewise, it was in the Dark Age cooling period that my Anglo ancestors, numbering anywhere from 5K to 20K, were pushed out in their own Trail of Tears from modern Germany into modern Denmark. Just like other Germanic tribes (the goth tribes) were pushed out of their homeland by the Huns in the Dark Age cooling period (which is what forced the Anglos and Saxons out of Germany).
I'm not justifying the many people groups who committed all those atrocities. But I am saying the leaders of those groups deserve a little slack for living in desperate times which often resulted in horrible measures against others. Low crop yields with the Huns was probably a major reason they migrated south and west (forcing the Gothic Germanic tribes from their homeland). During the Little Ice Age we know that Africa experienced mega-droughts lasting decades and devastating crop yields. This was probably a major factor in the spike of black tribes taking over crop land from neighboring tribes (and selling the inhabitants as slaves). And the Europeans struggling to survive in the Little Ice Age, including having trouble navigating trade routes over the frozen Himalayas after the Muslims took over Constantinople and was seizing whatever cargo ships they ran across, chose to try to find a new sea route around the globe to Asia (the accidental discovery of Americas). And once discovered, new crop land seemed very desirable when crop yields are way down. Then there's the need to work the land harder to get what you can out of it (demand side of slavery) and take over more land (displacing indigenous Americans). It's amazing what you'll do when many of your people starve.
Last but not least, remember the often discussed high death rate of black slaves on the Atlantic route? What they conveniently forget to tell you is that most of those deaths occurred on land in Africa in transit to the shore. Basically, Africa was experiencing the high rates of death by disease that Europe, the Middle East, and indigenous Americans were experiencing. Why? Because life in the cooling periods suck!!! As much as the political class wants us to fear covid, it's child's play compared to 40-60% of Europe dying from the Black Plague.
This is all recorded in history. Yet, we're somehow supposed to hate the Modern Warm Period? Not me.
I have done my own unscientific survey and find that virtually no one knows that we are currently in a warming period in the middle of an ice age cycle.
