CME s occur when huge bubbles of gas threaded with magnetic field lines are ejected from the Sun over the course of several hours. This can happen as often as two or three times per day but the frequency of occurrence has been increasing since 1995. These ejections have a strong influence on space weather, but could also have an effect on terrestrial weather as well. X-ray emissions from CMEs can have an effect on constituents of the upper atmosphere such as Nitric Oxide. This could also affect middle atmospheric species such as Ozone.
CMEs produce large changes in the magnetosphere, which affects the ionosphere.
S olar flares are actual explosions on the surface of the Sun. The effects of such a flare striking Earth are beyond imagination. I n addition to the direct dangers, the sun also serves to attract comets and asteroids that shoot past our planet at city smashing speeds. In the same way that associated crime comes with the opening of a casino or other den of inequity, these other dangers are increased tremendously by the presence of the sun. There are many that think a meteor collision is what killed the mighty dinosaurs that walked the Earth before us.
