In 1938, Guy Callendar connected carbon dioxide increases in Earth’s atmosphere to global warming. In 1896, a seminal paper by Swedish scientist Svante Arrhenius first predicted that changes in atmospheric carbon dioxide levels could substantially alter the surface temperature through the greenhouse effect. In the 1860s, physicist John Tyndall recognized Earth's natural greenhouse effect and suggested that slight changes in the atmospheric composition could bring about climatic variations.
In 1856, Eunice Foote discovered that blanket, showing that carbon dioxide and water vapor in Earth's atmosphere trap escaping infrared (heat) radiation. He suggested something in the atmosphere must be acting like an insulating blanket. In 1824, Joseph Fourier calculated that an Earth-sized planet, at our distance from the Sun, ought to be much colder. al., "An astronomically dated record of Earth’s climate and its predictability over the last 66 million years," Science vol.
