"The Bottom Line

Our Sun, like all stars, is a variable star. We must learn to live with the uncertainty of a star that is a product of its environment. We can expect our Sun to change when it enters regions of interstellar space where there is more or less dust, which alters the plasma characteristics. In the meantime, we can only look for reassurance by closely examining the behavior of nearby stars. A few massive CME's are the least of our concerns. "
