Abstract:

This paper puts forward a new idea in the study of the global temperature change. In order to discover the macroscopic rule of global temperature change, we consider the whole system of the biosphere in the broad sence as an intergrated material system and take it as our research object, so that we may treat the complicated issue of global temperature change as a classic physical problem of heat and temperature changes. A thermodynamic formula is presented to measure the value of Q and the temperature change in thermodynamic equilibrium for the biosphere in the broad sense. On the basis of experimental data, it is found that, in theory, the heat released by the use of fossil fuels and nuclear energy raises the global sea level by 35 mm per year or raises the temperature in the atmospheric troposphere by 0.11 ℃ per year. The result shows that the heat from energy source has become an important factor affecting the global temperature change.
