I don't know how many have seen these "experts" (with no scientific background) who've been in the media lately stating that the current solar irregular activity may lead to starilization of earth. Firstly Solar flairs don't really affect us, its the gaseous cloud that often accompanies it. Sun spots are created due to the differential axial rotation rates of different parts of the sun, which causes a "twisting" of the suns magnetic feild. This is stored energy (like twisting an elastic band) which enters the suns atmosphere and thus is seen as a darker sun spot. The suns core (site of nuclear fusion, protons to he nucleus) is the hottest part of the sun, followed by the suns atmosphere. then the suns surface. Hence the sun spot is cooler than the rest of the suns atmosphere we see. When this cloud, refered to as coronial ejection (not sure of the spelling at all) hits earths magnetic feild it compress's. Our satelites may be in trouble but by no means are we going to fry on earth. This is to the best of my understanding, however physics is not my particular discipline but i feel am a little more versed in this with respect to these blokes who haven't studied any physics.
