A brief history of climate change. Many experts considered 2 degrees C of warming to be a critical limit, which, if surpassed will lead to increasing risk of more deadly heat waves, droughts, storms and rising global sea levels. Part of the reasoning was that while smog could remain suspended in the air for weeks, CO2 could persist in the atmosphere for centuries. Most famous among those research projects was a monitoring station established in 1958 by the Scripps Institution of Oceanography on top of Hawaii’s Mauna Loa Observatory. In the 1800s, experiments suggesting that human-produced carbon dioxide (CO2) and other gases could collect in the atmosphere and insulate Earth were met with more curiosity than concern. History of climate change studies Joseph Fourier in 1824, Claude Poulliet in 1827 and 1838, Eunace Foote (1819–1888) in 1856, Irish physicist John Tyndall (1820–1893) in 1863 onwards, Svante Arrhenius in 1896, and Guy Stewart Callendar (1898–1964) are credited with discovering the importance of CO 2 in climate change.
