Solar magnetism is responsible for the several active phenomena that occur in the solar atmosphere. The consequences of thesephenomena on the solar-terrestrial environment and on Space Weather are nowadays clearly recognized, even if not yet fully under-stood. In order to shed light on the mechanisms that are at the basis of the Space Weather, it is necessary to investigate the sequenceof phenomena starting in the solar atmosphere and developing across the outer layers of the Sun and along the path from the Sun tothe Earth. This goal can be reached by a combined multi-disciplinary, multi-instrument, multi-wavelength study of these phenom-ena, starting with the very first manifestation of solar active region formation and evolution, followed by explosive phenomena(i.e., flares, erupting prominences, coronal mass ejections), and ending with the interaction of plasma magnetized clouds expelledfrom the Sun with the interplanetary magnetic field and medium. This wide field of research constitutes one of the main aims ofCOST Action ES0803: Developing Space Weather products and services in Europe. In particular, one of the tasks of this COSTAction was to investigate the Progress in Scientific Understanding of Space Weather. In this paper we review the state of the art ofour comprehension of some phenomena that, in the scenario outlined above, might have a role on Space Weather, focusing on theresearches, thematic reviews, and main results obtained during the COST Action ES0803.
