Svante August Arrhenius (; 19 February 1859 – 2 October 1927) was a Swedish scientist.
Originally a physicist, but often referred to as a chemist, Arrhenius was one of the founders of the science of physical chemistry.
He received the Nobel Prize for Chemistry in 1903, becoming the first Swedish Nobel laureate.
In 1905, he became director of the Nobel Institute, where he remained until his death.Arrhenius was the first to use basic principles of physical chemistry to estimate the extent to which increases in atmospheric carbon dioxide are responsible for the Earth's increasing surface temperature.
In the 1960s, David Keeling demonstrated that human-caused carbon dioxide emissions are large enough to cause global warming.Arrhenius' contributions to science are memorialized by the Arrhenius equation, Arrhenius acid, lunar crater Arrhenius, Martian crater Arrhenius, the mountain of Arrheniusfjellet, and the Arrhenius Labs at Stockholm University.
