You:"Sun spots have been proven to change climate, and they have nothing to do with cosmic rays. "The article:"Cosmic rays are deflected away from Earth by our planet's magnetic field, and by the solar wind "The article refutes a study that supposed solar wind's deflection of extra-solar cosmic rays was corelated to cloud density over the earth, with some effect on earth's climate. The first part is true, solar wind effectively reduces external cosmic rays, so they do have something to do with cosmic rays. In fact if the article and your post weren't so imprecise, it could be said that the two were the same, solar and external cosmic rays.
Again, solar winds/ cosmic rays, have zilch to do with sun spots.
Without our planet's magnetic field, Earth would be subjected to more cosmic radiation. The increase could knock out power grids, scramble the communications systems on spacecraft, temporarily widen atmospheric ozone holes, and generate more aurora activity.
On average, every eleven years solar activity is high. The magnetic field of the sun increases, solar flares are more common, which produce magnetic clouds and therefore cosmic rays are deflected stronger than during a solar minimum. Thus, when the sun is active, fewer galactic cosmic rays reach Earth's atmosphere in order to produce secondary particles.
I'm not sure I want to be here when the poles shift again.So much of our everyday life will be effected by such an event. navigation as we know it will be impossible. Anything that depends on the magnetic field will be affected. It'll be interesting, but not in a "hey this is cool" way
