Ecological Systems and Devices Annotation << Back Climatic of changes. Warming up or temperature of drop? Solovyev L.P. Within the problem analysis «warming or a cold snap» are considered the main physical and chemical processes defining formation of climate of Earth. During the review the attention is paid that so-called «greenhouse gases» methane, nitrous oxide, oxide of carbon can't really have impact on intensity of greenhouse effect. It is thus noted that increase of concentration of oxide of carbon can be a consequence of water temperature increase at oceans. It is emphasized that the main greenhouse a component of the atmosphere is the water vapor which influence on process of warming increases, owing to growth its concentration in the atmosphere. By consideration of dynamics of mutually amplifying couple temperature – humidity is present and a slowing-down factor – salinity of sea water which lately grows. Within fundamental situation that the condition of climate on Earth is determined by the size of energy arriving on it and mechanisms of redistribution of this energy by a planet surface, its main components are characterized. In the course of consideration of the major climatological factors, data on decrease in power of radiation of the Sun since 1990 are provided. During the analysis of mechanisms of redistribution of thermal energy on a planet surface, it is noted that processes of circulation of air masses in the atmosphere and movements of water streams of ocean currents are defined by a large number of the factors which interrelation is insufficiently studied. In the conclusion the conclusion is drawn that for the unambiguous conclusion about an orientation of climatic changes of data it is obviously not enough, and only already developed and planned climatological programs will help to resolve this problem.
