A closer look
Roman Empire may have expanded not just because of politics, but because of the weather. Researchers studying tree rings and sediment cores reveal that the empire’s greatest growth coincided with 200 years of unusually stable and mild climate—warm summers, steady rains, reliable harvests. When those conditions changed, droughts and famines began to destabilize society. This historical lesson whispers a warning to us today: our own economies and cultures depend on climate harmony more than we like to admit. Stability, not just strength, builds empires.
