The experts of the Kazan Federal University have announced that temperature rising in the northern hemisphere for the last 37 years has stopped short.

According to the opinion of Prof. Yury Perevedentsev, the Head of the KFU Department of Meteorology, Climatology and Atmosphere Ecology, a period of global cooling is approaching the northern hemisphere.

The conclusion has been made by the Russian scientists upon the analysis of the long-term average annual changes of air temperature, wind speed, and atmosphere pressure in the northern hemisphere over 1948-2013. This data, by Yury Perevedentsev, indicate the period of climate processes denying the global warming theory.  

Besides, the Russian scientists have discovered the direct correlation between the curves of temperature and wind speed. The latter influences 60% of temperature change in some regions, with some delay, however. 

According to the Russian scientists' observations, the average wind speed in the northern hemisphere lowered 8 years ago, as a result, in 2013 the average annual temperature ran down. Therewith the 37 year-long warming period has had an unsteady impact on the tropics, midland and circumpolar area. The most significant annual temperature increase has been registered in the circumpolar area (2.38 degrees). In the midland the average annual temperature has grown by 0.7 degrees, even less at the equator (0.54 degrees).

The Russian experts blame El Niño, the process of the oscillation of water surface temperature in the equatorial part of the Pacific Ocean. According to Yury Perevedentsev, the water temperature in the equatorial part of the Pacific Ocean may rise up by 10 degrees and seriously influence sea currents and the circulation of air masses. Thus, El Niño together with the sun activity and irregular movement of the Earth (faster in winter) form the wind speed on our planet and causes cyclic warming and cooling.

The theory of the Russian experts about the approacing cooling period is supported by the hypothesis of Khabibullo Abdusomatov, the Head of Space Research Sector of the Main (Pulkovo) Astronomy Observatory, that suggests the sun activity should reach its minimum by 2042 and cause the lowering of the Earth's temperature by1-1.5 degrees. At this time the temperature will not change at the equator, whereas people at high latitude will face extremely severe winters.
