#dyslexie_créative dirait Erratic motion of north magnetic pole forces US government shutdown.
Il y a bien du #shutdown dans l’air, chapeau de Nature :
Update, 9 January: The release of the World Magnetic Model has been postponed to 30 January due to the ongoing US government shutdown.
avec les conséquences pratiques (imperceptibles, pour the rest of the world)
Beggan said the recent shifts in the north magnetic pole would be unnoticed by most people outside the Arctic, for instance using smartphones in New York, Beijing or London.
Navigation systems in cars or phones rely on radio waves from satellites high above the Earth to pinpoint their position on the ground.
“It doesn’t really affect mid or low latitudes,” Beggan said. “It wouldn’t really affect anyone driving a car.”
Many smartphones have inbuilt compasses to help to orientate maps or games such as Pokemon Go. In most places, however, the compass would be pointing only fractionally wrong, within errors allowed in the five-year models, Beggan said.
