This fog over London killed 12,000 people in just one week. This happened in 1952. On December 4, London fell into the anticyclone zone, a cold fog descended on the city.
The fog had no way to dissipate. And inside this fog accumulated exhaust gases that had no outlet, factory emissions, soot particles from hundreds of thousands of fireplaces. The situation was getting worse every day. Visibility decreased so much that it was necessary to stop the movement of public transport, with the exception of the subway. People couldn't even see their feet. Even the work of the ambulance was stopped: there was simply no way to pick up patients. Theater performances and cinema screenings stopped — the audience did not see either the stage or the screen.
