Apparently, like the esteemed Samuel Langhorne Clemens, reports of the Earth’s magnetic force’s demise are greatly exaggerated. The Earth’s magnetic force is just as strong now as it was 3.2 million years ago. For those of you who may have been loosing sleep over this issue, you’ll be happy to know we have no chance of loosing our atmosphere a la Mars anytime soon. I know that’s one thing I can mark off my worry list!
