John Tyndall photographed by Barraud. These works earned him the appreciation of Michael Faraday, who became his mentor. He was made a Fellow of the Royal Society in 1852 and, from 1856, was a member of its Council. 12. John Tyndall was already a familiar and well-known scientist among the growing number of scientific clubs, societies and institutions of London in mid-Victorian Britain (Lightman, 2007). In 1859/1860 John Tyndall discovered that carbon dioxide absorbed long wavelength (heat) radiation. Han ble første gang kjent da han i 1850-årene utførte studier vedrørende diamagnetisme. John Tyndall (født 2. august 1820 i Leighlinbridge i Carlow i Irland, død 4. desember 1893 i Hindhead i Surrey i England) var en irsk fysiker som gjorde betydelige bidrag innenfor flere forskjellige felter, spesielt elektromagnetisk stråling og atmosfærefysikk.
Formally, the Irish scientist launched his career as a reputed physicist thanks to his studies on diamagnetism, the repulsion on which superconductors or magnetic levitation trains are based. John Tyndall, Proceedings of the Royal Society of London, 1860-1862, 11, pp 100-104. JMcG: Unlike H2O which has a huge capacity to absorb IR energy, CO2’s capacity to absorb radiation is small.

Shorn of Tyndall’s insularity, this is a description of the ‘greenhouse effect’, which is now recognised as one of the major drivers of global climate change. Claude Piollet, John Tyndall...) Début du 20ème siècle: des scientifiques (T.C. Bill Butler: Virtually the entire field of infrared spectrography as applied to atmospheric science, beginning with the work of John Tyndall in the 1800's, is fraudulent. CO2 absorbs no significant infrared energy compared to water. It is saturated immediately. So, there really is no drama in Tyndal’s discovery. However, perhaps his most original contributions were …
