fog | National Geographic Society

Pea Souper A "pea souper" is a type of fog that forms when water condenses around microscopic particles of coal. This fog is often a brownish-yellow color, leading to the name. Pea soupers are common in areas that burn coal for energy. The London Fog of 1952, which killed 12,000 people around the urban center of London, England, was a pea souper.

About Coal Mine Methane | US EPA

CMM refers to the methane released from coal and the surrounding rock strata from mining activities. This methane in mines poses a safety risk due to its explosiveness when mixed with air. Methane is also a greenhouse gas that is more than 25 times more potent than carbon dioxide on a mass basis over a 100-year time period ( learn more about ...
