I'm sure you have heard the term "polycrisis". It seems to be growing in popularity as "the term" for what you are describing.

I liked your breakdown of the Potato Famine. Although I think you glossed over the role of the British in the disaster.

I also don't think you appreciate the MAGNITUDE of the Climate Shock that's about to happen.

800 million to 1.5 billion are going to starve by 2030. That's the FIRST ORDER consequence.

Everything else in this polycrisis will flow from that.
