Astrophysical fluids have high Reynolds numbers and this makes them turbulent. Turbulent fluids have properties that are radically different from their laminar counterparts. I will discuss first how turbulence affects the process of magnetic reconnection and show that it induces gross violation of the textbook concept of the flux freezing. Implications of solar magnetic activity on Earth activities and telecommunications will be discussed, as well as its influence on the "space weather".
