Guy Stewart Callendar (/ˈkæləndər/; 9 February 1898 – 3 October 1964) was an English steam engineer and inventor.[1] His main contribution to human knowledge was developing the theory that linked rising carbon dioxide concentrations in the atmosphere to global temperature. In 1938, he was the first to show that the land temperature of Earth had risen over the previous 50 years.[2] This theory, earlier proposed by Svante Arrhenius,[3] has been called the Callendar effect. Callendar thought this warming would be beneficial, delaying a "return of the deadly glaciers."[4]
