Abstract: | A model consisting of two blocks (equations) was proposed for the analytical study of the biosphere-climate system over great periods of time. The first equation describes the balance of carbon dioxide in the atmosphere and represents the biological block of the model. The second equation is the equation of the energy balance or the physical block of the system. The model is based on the most general conceptions of living matter and the evolution process. A possible interpretation of some events and phenomena in the earth history in terms of the model is given. |
