The debate was won many decades ago: Based on information from his colleague Arvid Högbom , Arrhenius was the first person to predict that emissions of carbon dioxide from the burning of fossil fuels and other combustion processes were large enough to cause global warming. In his calculation Arrhenius included the feedback from changes in water vapor as well as latitudinal effects, but he omitted clouds, convection of heat upward in the atmosphere, and other essential factors. His work is currently seen less as an accurate prediction of global warming than as the first demonstration that it should be taken as a serious possibility. en.wikipedia.org Inspired by the work of Tyndall and Arrhenius , Chamberlin in 1896 had the geological effect of atmospheric CO2 as overall course theme, and based on this, he in 1897 published a CO2 hypothesis of glaciation, entitled "A Group of Hypotheses Bearing on Climate Changes ". Chamberlin proposed that variations of atmospheric CO2 combined with water vapour feedbacks could account for the advance and retreat of the past ice sheets. In this publication, although strongly inspired by the work of Arrhenius, he was critical of the idea proposed by Arrhenius and H ögbom , that volcanism controlled the amount of atmospheric CO2. Instead, Chamberlin suggested that it was weathering of exposed bedrock which represented a main control on atmospheric CO2. In addition, he was the first to introduce the question of how much carbon was contained in various reservoirs, including the oceans, atmosphere, solid earth, and biosphere ( Fleming 1998 ). climate4you.om
