Global energy and climate of the planet in the XXI century in the context of historical trends

The paper deals with global energy perspectives and forthcoming changes in the atmosphere and climate under the influence of anthropogenic and natural factors. In the framework of the historical approach to energy development the forecast of the future global energy consumption for the present century is made, and its resource base and the global consequences of the impact of the power sector on the atmosphere and climate on the background of natural factors are studied. It is shown that, following the historical tendency for global energy evolution, the global energy consumption by the end of the century will remain within 26 bln. tce, with CO2 emissions peaking in the middle of the century. In this scenario, the CO2 concentrations will not exceed 500 ppm, and the global temperature should rise by 1.5 degree by 2100, with the growth rate not exceeding the adaptation limits of the biosphere.
