The paper researches the time resource to be beforehand with climate changes. The feature of the research consists in the following: the evolutionary properties of the local climate dynamics are considered from the bifurcation analysis, and adaptive properties are considered from the control theory. Then the principal event-driven scenario of the climate change birth is revealed over the period of the reliable meteorological observations; next, the rate of its development is estimated in the context of factually realized precedents; so, time horizons of prognostic indicators are determined. The research is founded on the regulatory theory on local climate dynamics. The analytical conclusions are illustrated by examples of processing the open-access data on daily mean air surface temperature in the continental part of Russia.
