THE ROLE OF TECHNOGENESIS IN GLOBAL CLIMATE CHANGES
The paper deals with the problem of human activities effect on the Earth climate changes, in particular, the present increase of the atmospheric and earth surface average temperature. Due to investigations conducted it was found that the main factor of these processes is not technogenesis which increases carbonic acid content and serves as a screen for heat current from the Earth, but natural development of events peculiar to our planet. The present Earth climate warming results from the advent of the regular warming rhythm to be followed by the cold spell, both caused by geological and space factors. The rise in average atmospheric temperature is aggravated and accelerated by anthropogenic effect, including industrial discharge of carbon dioxide. Rhythmical alternation of rises and falls in temperature bringing glaciers of different orders used to be even before a man appeared on the Earth. This does not make the problem of nature preservation less urgent, as the consequences of uncontrollable processes unfavourable for environment may result in regional and local ecological catastrophes, deteriorating human living conditions on the Earth.
