On May 20, Sunday, much of the United States was treated to an annular solar eclipse when the Moon gets directly between the Earth and the Sun. There is another interaction with the sun, however, that holds the potential for tremendous harm and solar scientists are warning we could be in for one as a cycle of such flares is peaking.
The Sun gives off solar flares all the time, but they rarely are noticed or impact the Earth because our atmosphere serves as a kind of cocoon—the magnetosphere—that deflects these bursts of electromagnetic energy.
A large flare is ten times the amount of energy released by a volcanic eruption, something along the lines of millions of 100-megaton hydrogen bombs exploding at the same time, but is less than one-tenth of the total energy emitted by the Sun every second.
As Robert W. Felix, author of “Not by Fire, but by Ice”, says, “Our magnetic field is one of the best described and least understood wonders of the universe.” What is known is that the Earth has been through a series of magnetic reversals and they line up with mass extinctions of life. What is known is that interglacial periods are about 11,500 years long and we are at the end of such a period. Felix has been warning that the Earth is on the cusp of a new Ice Age.
Everything on earth, its plant and animal life, is directly affected by the Sun and we are most aware of it with the passing of the seasons from warm summers to cold winters. The rest of the time we just check the weather report to learn whether it is going to be a rainy or sunny day.
