Solar activity is equivalent to a new ice age





Disturbing is the fact that after a deep recession in 2006-2009. and is encouraging small rise in recent years, in 2012, solar activity has stopped rising and dropped below the level of the previous 2011. According to laboratory X-ray astronomy of the Sun at the Physics Institute of the Academy of Sciences, the current level of activity is 4 times lower than the maximum values ​​recorded during the 260 years of continuous observations of the Sun, and only a few percent higher than during the Dalton minimum (from 1784 to 1810 years ).
During the period of instrumental observations of the Sun found 23 solar cycles, the latter of which peaked at the turn of 2000 and 2001, and was completed in December 2008. Since the second half of 2009, the sun began to register the new growth activity, it is the beginning of next, the 24th, cycle. At the same time reach the peak of their activity the Sun was in this year 2012.
But it did not. Why? Above the scientists scratching their heads. Perhaps the 11-year cycle of activity imposed long-term fluctuations, which have been identified by scientists.
Under the most pessimistic estimates, it is possible that current events are a harbinger of a new major failure of solar activity lasting at least several solar cycles - from 25 to 100 years. If so, then cry notorious global warming.
Scientists believe that the Sun is still 6-12 months, to significantly increase the activity (1.5-2 times) and return quiet sleep geophysicists. If it does not, then it becomes obvious fact that light passes through one of the lowest in the history of cycles, which were previously recorded only during prolonged activity faults, almost inevitably accompanied by abrupt changes in the Earth's climate.
