An international study of the most recent near reversals of the Earth’s magnetic field has found that it is unlikely that such an event will take place soon. They studied two more recent geomagnetic excursion events, Laschamp, about 41,000 years ago, and Mono Lake, about 34,000 years ago, where the field was about to revert, but regained its original structure. The last time a geomagnetic reversal happened was 780,000 years ago. In Spanish: bit.ly/2KpZ58D Rel .: menea.me/1qg07
