A setup has been devised to measure the effect of Kozyrev's interaction of natural geophysical and solar processes, treated as macroscopic non-locality. The detectors used in the setup have efficiency three orders of magnitude better than ones used before. Exhaustive steps have been taken to control noise-forming factors and protect the detectors against them. As a result, effects of non-social influences of several large-scale processes related with weather changes, geomagnetic variations, ionospheric and solar activity have been reliably detected. A large advanced lag has been found in a number of processes, which might be used in the geophysical forecasts.
The theoretical and experimental development of the causal mechanics suggested by N.A. Kozyrev is here reviewed. The ideas of causal mechanics have met a contradictory reaction because, on the one hand, formalization of the theory has been weak and there has been doubt about the rigor of experiments, but on the other hand, those experiments have again and again showed reproducibility. Recently, the basic statements of causal mechanics have been strictly formulated. A connection of causal mechanics with action-at-a-distance electrodynamics and quantum non-locality has been revealed. Kozyrev's experiments have been reproduced successfully at the different labs. There is the possibility of using causal mechanics to explain the interaction of macroscopic dissipative processes, and for forecasting in geophysical and astrophysical applications.
The difficulties of gaining acceptance of the causal mechanics by N. A. Kozyrev are due to its fundament of indefinite concepts such as "cause," "consequence," etc. Based on the information approach a formal definition of causality can be given. This has made it possible to formulate the basic concepts of the theory, including the arrow of time.
