The global warming caused by the green-house gases effect will be equal or less than the global cooling as a result of the current era of weak solar activity. In this respect, we refer to the Modern Dalton Minimum (MDM), according to which the earth’s surface temperature will become cooler than nowadays, starting from the year 2005 until the year 2050. However, the degree of cooling, previously mentioned in old Dalton Minimum (c. 210 y ago), will be minimized by building-up of green-house gases effect during the MDM period. Regarding to the periodicities of solar activities, it is clear that now we have a new solar cycle of around 210 years. This paper analyses solar-X activity data given by GOES satellite to predict the incoming effects of the MDM on the climate change, global precipitation and the change of dryland areas all over the Earth surface
