What is the climate waiting for Russia and Europe in 15-20 years? Will be there weather abnormalities in the coming decades? Will some areas experience more severe winter, while the others will have hot summer? It all depends on how much the climate will be affected by the dynamics of the possible onset of minimum solar magnetic activity. The Sun's behaviour in future cycles is the main theme of a publication on the forecast and explanation of the minima of solar activity. The paper was prepared with contributions from Elena Popova from the Skobeltsyn Institute of Nuclear Physics (Lomonosov Moscow State University) and was published in Scientific Reports.Scientists have studied the evolution of the solar magnetic field and the number of sunspots on the Sun's surface. The amplitude and the spatial configuration of the magnetic field of our star are changing over the years. Every 11 years the number of sunspots decreases sharply. Every 90 years this reduction (when it coincides with the 11-year cycle) reduces the number of spots by about a half. A 300-400 year lows reduce their numbers almost to zero. Best known minimum is the Maunder minimum, which lasted roughly from 1645 to 1715. During this period, there were about 50 sunspots instead of the usual 40,000-50,000.
