Callendar effect

From Wikipedia, the free encyclopedia

The Callendar effect is a name for the effect of combustion-produced carbon dioxide on the global climate. It is therefore a special case of the greenhouse effect. The size of the Callendar effect is a controversy in global warming.

The Callendar effect is named after Guy Stewart Callendar (1898-1964), who proposed the effect in 1938 based on earlier work by John Tyndall and Svante Arrhenius. He was the son of Hugh Longbourne Callendar (1863-1930), an English physicist. Among HL Callendar's inventions was a rolling-chart thermometer that allowed long-duration collection of climatic temperature data.
