Vostok ice core data NOAA Mauna Loa CO 2 record Gilbert Plass formulated the Carbon Dioxide Theory of Climate Change in 1956. In 1941, Milutin Milankovic linked ice ages to Earth’s orbital characteristics. 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.

This ancient, or paleoclimate, evidence reveals that current warming is occurring roughly ten times faster than the average rate of ice-age-recovery warming. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks. Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that Earth’s climate responds to changes in greenhouse gas levels. There is no question that increased levels of greenhouse gases must cause Earth to warm in response. 2 Their ability to affect the transfer of infrared energy through the atmosphere is the scientific basis of many instruments flown by NASA. The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century. This body of data, collected over many years, reveals the signals of a changing climate. 1 It is undeniable that human activities have warmed the atmosphere, ocean, and land and that widespread and rapid changes in the atmosphere, ocean, cryosphere, and biosphere have occurred.Įarth-orbiting satellites and other technological advances have enabled scientists to see the big picture, collecting many different types of information about our planet and its climate on a global scale. The current warming trend is of particular significance because it is unequivocally the result of human activity since the mid-20 th century and proceeding at a rate that is unprecedented over millennia.
