[QUOTE="Opmmur, post: 58278, member: 13"] [SIZE=4]A new study indicates that there is a possible connection between the Earth's inner core and a magnetic reversal. [/SIZE] [SIZE=4]The magnetic field reverses direction every few thousand years. If it happened now, we would be exposed to solar winds capable of knocking out global communications and power grids. [/SIZE] [SIZE=4]Peter Olson and Renaud Deguen of Johns Hopkins University in Baltimore, Maryland, used numerical modelling to establish that the axis of Earth's magnetic field lies in the growing hemisphere. While one side of Earth's solid inner core grows slightly, the other half melts, the scientists concluded in their research paper. [/SIZE] [SIZE=4]Now the researchers speculate that there are signs that the next magnetic pole reversal may be underway. [/SIZE] [SIZE=4]The rapid movements of the field's axis to the east in the last few hundred years could be a precursor to the north and south poles trading places, the researchers suggest.
