John Tyndall (/ ˈ t ɪ n d əl /; 2 August 1820 – 4 December 1893) was an Irish physicist.His scientific fame arose in the 1850s from his study of diamagnetism.Later he made discoveries in the realms of infrared radiation and the physical properties of air, proving the connection between atmospheric CO 2 and what is now known as the greenhouse effect in 1859.
John Tyndall's ratio spectrophotometer (drawing from 1861) measured how much infrared radiation was absorbed and emitted by various gases filling its central tube. [1] Such measurements furthered understanding of the greenhouse effect that underlies global warming and climate change.
The greenhouse effect occurs when greenhouse gases in a planet's atmosphere insulate the planet from losing heat to space, raising its surface temperature. Surface heating can happen from an internal heat source (as in the case of Jupiter ) or come from an external source, such as its host star .

In 1856 Eunice Newton Foote demonstrated that the warming effect of the sun is greater for air with water vapour than for dry air, and the effect is even greater with carbon dioxide. John Tyndall was the first to measure the infrared absorption and emission of various gases and vapors. From 1859 onwards, he showed that the effect was due to a ...
The Earth's energy imbalance is the "net absorbed" energy amount and grew from +0.6 W/m 2 (2009 est.) to above +1.0 W/m 2 in 2019.
