Yep....and because most people's thinking needs to be reprogrammed RE our active and changing climate, we will have to reinvent the wheel.
We don’t have to reeducate most people though. Just those who produce food in bulk.
Also there’s the fact that we can transport large amounts of food around the globe from where they grow as things shift.
I’ve been warning of global cooling for years (based on solar cycles). A guy I knew (kooky genius type) also believed it. He went so far to study seeds, modify plants etc. for cold weather. Worked with a university in Sweden. He has a bunch of seeds he developed locked up in a vault and buried in some mountain up there.
The only trouble with global cooling, it also can mean less rainfall. (More water locked up in the ice and snow).
