The role of biodiversity in the conservation of the Earth climate and human civilization. The problems of geobiophysics

Factors affecting the concentration of CO2 in atmosphere were analyzed, and the conditions providing the Earth termal balance stability were considere d. It was shown that the antropogenic decrease of biodiversity in climate-f orming biosystems, such as swamps and tropical seas, may lead to the greenh ouse disaster, resulting in the raise of the temperature on the Earth's sur face up to 300 degrees C and elimination of Life an Earth. By the example o f the ecologycal disaster caused by the introduction of the European mollus c Dreissena into fresh waters of the North America, which was predicted by us, it; was shown that the main reason! for the decrease in biodiversity, w hich can accelerate the greenhouse disaster, is the violation of one of the Darvin principles of species formation, the principle of geographical isol ation of species. It is shown in terms of a new model of periodical glaciat ion of the Northern Hemisphere that the elevation of Earth surface temperat ure caused by an increase in CO2 concentration in the atmosphere can substa ntially accelerate the onset of a new glacation period in the Northern Hemi sphere, which may decrease the greenhouse disaster rate. The necessity of t he formation of a new interdisciplinar scientific branch, geobiophysics, is consdidered.
