文摘The purpose of this paper is to present a simple way to approximate the dependence of the global mean air temperature at Earth＇s surface on atmospheric concentration of carbon dioxide. Current discussions include energy aspects of the greenhouse effect and the global warming. The starting point for the research are laws of thermodynamics, energy equilibrium and absorption and emission property of the atmosphere. According to the calculations, the natural and the anthropogenic changes effect the atmosphere. By the year 2100 the CO2 concentration will be doubled in comparison with the value of the pre-industrial ages. The doubled CO2 concentration will mean a temperature change about 1 ℃-1.5 ℃.
