The Cold That Broke the Roman Empire

Rome could handle invasions, plagues and civil wars. What it couldn't handle was a few degrees. When the rivers that formed its frontier froze solid, the border stopped being a border. When the harvests failed year after year, the grain fleet couldn't fix it. And when a volcano on the other side of the world threw enough ash into the sky to dim the sun, the world got cold in a way nobody could explain at the time. This is the story of how a climate downturn hit the ancient world — what Romans actually did to stay warm, why glass windows and heated floors were luxuries most people never saw, what happens to a city of a million people when the grain stops arriving, and how we can now read the whole thing out of ice cores and tree rings thousands of years later.
