And nobody was talking about global warming at the time …
In late January 1910, following months of high rainfall, the Seine River flooded Paris when water pushed upwards from overflowing sewers and subway tunnels and seeped into basements through fully saturated soil.
The waters did not overflow the river’s banks within the city but flooded Paris through tunnels, sewers, and drains. In neighbouring towns both east and west of the capital, the river rose above its banks and flooded the surrounding terrain directly.
Winter floods were a normal occurrence in Paris but, on 21 January, the river began to rise more rapidly than normal. Over the course of the following week, thousands of Parisians evacuated their homes as water infiltrated buildings and streets throughout the city, shutting down much of Paris’ basic infrastructure.
