i saw an article the other night on public television of the earth's decreasing magnetism. does anyone have an idea what is going to happen in the next thousand years to the earth's "blanket"? i understand it will renew back, as it has many times in the past, although the poles will shift, but what will that mean to humanity? of course no one is at threat born today even in a worst case senario, or are they? who knows? who has an idea? given evidence of the past, no major event on earth has left life on earth unaffected in some way.
