I heard that the magnetic field Reverse polarity of the Earth in 2012, when there will be as predicted, the strongest in the history of solar storms. Do we die then? And whether our civilization is destroyed? As we approach the period of maximum solar activity (which occur about every 11 years), there is a lot more solar flares and mass emissions of the coronary than in periods of minimum solar activity. Outbreaks and mass emissions are not risk to humans or other species of life on Earth. They could endanger the astronauts living in deep space or on the moon, and this is something with which NASA must learn somehow to fight, but it’s not yours and not my problem.
Powerful flares can disrupt radio system, cause the appearance of colorful aurora (northern and southern auroras), disable the electronics of satellites located in space. Today, many satellites are designed in such a way as to cope with this problem, for example, by disabling some of the most sensitive circuits, and the transition to the ‘secure’ mode for several hours. In extreme situations, solar activity can also disrupt power lines on the ground that can lead to complete disconnect from the electricity of entire regions, but this is rare. The last period of maximum solar activity took place in 2001, so next time predicted by about 2012, after 11 years. True, the last period of minimum solar activity was unusual, it was only a couple of years, during which almost no sun spots and other signs of solar activity, so that scientists now believe that the next period of maximum solar activity is delayed, possibly until 2013.
