Question

Explain what was ultimately responsible for London’s “killer fog” in 1952. short paragraph

Answer 1

London’s “killer fog” of December 1952 was ultimately caused by a lethal combination of heavy coal smoke and industrial emissions (rich in sulfur dioxide and particulates) trapped close to the ground by a temperature inversion and a stagnant high‑pressure weather system. The pollutants reacted on soot particles to form dense, acidic aerosols and black smog that reduced visibility and severely damaged respiratory and cardiovascular health, leading to thousands of excess deaths and widespread illness. The disaster prompted major clean‑air legislation (the 1956 Clean Air Act) that reduced coal smoke emissions in cities.
