Cloudage conditions over the territory of the Siberian region is studied on the basis of multiyears (1966-2012) ground-based observations for the amount of total and lower cloudiness. The monthly and seasonal means of the amount of clouds and their annual variations, as well as long-term fluctuations of the amount of total and lower cloudiness are considered in the context of modern global climate change. It is ascertained, that the greatest amount of total and lower cloudiness is observed in all seasons and in the whole year in the polar latitudes, and least one is noted in the temperate zone. Two of the clouds maximums (main in spring, and the less expressed second in May-June) are observed in the annual variations of the amount of the clouds almost everywhere, except the station Chita. Increase of amount of total and lower cloudiness (concerning the norm for 1966-1985) is revealed in the period 1986-2005, when global warming was observed over the territory of the Northern hemisphere. However, in subsequent years (2006-2012), in the period of the beginning of cooling, the amount of low clouds over Western Siberia is reduced during the continued growth of the amount of total and lower cloudiness occurring everywhere
