Key Notes
diagnosis
The Bronze Age world collapses around 1200 BCE through a perfect storm of climate change, drought, famine, migration, Sea Peoples attacks, and regional vulnerability.
model
Old agricultural Europe collapses because static agriculture, disease, and climate change reduce population and create an opening for Yamnaya invasion.
diagnosis
Jiang identifies the 4.2 kiloyear event as a global climate shock that ended Egypt's Old Kingdom, ended the Akkadian Empire, weakened trade networks, and caused IVC cities to depopulate.

model
The current scholarly theory is described as perfect storm or systems collapse: not one event in one year, but decades of earthquakes, climate cooling, and internal revolt.
diagnosis
He names plague, climate change, and Yamnaya colonization as the three things that destroyed old Europe, with plague as the most important.
model
Jiang says agriculture began in warmer, fertile regions such as Anatolia, Egypt, and Mesopotamia, then moved into Europe when climate and soil pressures pushed farming families outward.
model
He says the AI should generate scenarios for shared problems like climate change and war so people can agree on actions and stick together.
