@Eduardo Mtnz@facebook If there is a pole shift, it will only be the magnetic field that shifts, like the story highlighted: "There's also the idea that the planet will switch its magnetic poles, which does happen every few hundred thousand years, but all that would mean for us is that our compasses would point south instead of north."
Not a huge deal.
@Joel Palmer@facebook Multicellular life has about 250-750 million years until the Sun becomes too hot. The Sun itself has about another 5 billion years or so. We have nothing to worry about.
