"Home Made" Model to Study the Greenhouse Effect and Global Warming
Onorato, P.; Mascheretti, P.; DeAmbrosis, A.
European Journal of Physics, v32 n2 p363-376 Mar 2011
In this paper a simplified two-parameter model of the greenhouse effect on the Earth is developed, starting from the well known two-layer model. It allows both the analysis of the temperatures of the inner planets, by focusing on the role of the greenhouse effect, and a comparison between the temperatures the planets should have in the absence of greenhouse effect and their actual ones. It may also be used to predict the average temperature of the Earth surface in the future, depending on the variations of the concentration of greenhouse gases in the atmosphere due to human activities. This model can promote an elementary understanding of global warming since it allows a simple formalization of the energy balance for the Earth in the stationary condition, in the presence of greenhouse gases. For these reasons it can be introduced in courses for undergraduate physics students and for teacher preparation. (Contains 6 footnotes, 3 tables, and 4 figures.)
