Svante August Arrhenius (19 February 1859 – 2 October 1927) was a Nobel Prize-winning Swedish scientist who made discoveries in physics, chemistry and earth science.

Originally he was a physicist, but he won the 1903 Nobel Prize in Chemistry, and was a founder of physical chemistry.

Later in life, he turned to other scientific problems. He was the first person to predict that emissions of carbon dioxide, from the burning of fossil fuels, would cause global warming.
