SEASONAL FEATURES OF LONG-TERM CHANGES OF GLOBAL CLIMATE AND THEIR POSSIBLE REASONS
Questions of interpretation of climate research results in various existential scales are considered in the article. Special attention is paid to debatable questions of the estimation of greenhouse gases and aerosols role assessment in the formation of seasonal features of temperature change in Northern and Southern hemispheres. It has been shown, that the parity of contribution of aerosols and greenhouse gases in the change of modern climate essentially varied in different periods of last 130 years. Climate warming in 1920-1940-s' years was the warming of summer type and it is differed from climate warming which has begun in the middle of the 70’s and which is connected greatly with greenhouse gases increase in the atmosphere. Clarification of atmosphere from aerosol has coincided with periods of greater summer positive anomalies of temperature in comparison with winter. The periods when aerosol pollution of the atmosphere was below the norm, are fixed in 1881-1901, 1924-1945 and 1996-2012. For the last 15 years, though values of positive anomalies of temperature during both seasons also remained high, the rise of winter anomalies of temperatures slowed down, whereas for summer anomalies of temperatures such essential delay of positive trends of temperature has not occurred. These features contradict maximum growth rate of greenhouse gases in the atmosphere.
