The Great London Smog of 1952

The Great London Smog of 1952 was a severe air pollution event caused by a combination of cold weather, atmospheric conditions, and increased coal burning for heating. A thick fog mixed with smoke and pollutants created a dense, toxic smoke over London that lasted several days. Visibility dropped dramatically, and many people suffered respiratory problems. It is estimated that around 4,000 to 12,000 people died prematurely due to the smog, prompting changes in air quality laws and pollution control. The event highlighted the severe health impacts of air pollution and led to ongoing efforts to improve environmental standards.
