schwit1 quotes Nature:
Something bizarre is occurring on the most sensible of the arena. Earth’s north magnetic pole has been skittering clear of Canada and in opposition to Siberia, pushed via liquid iron sloshing inside the planet’s core. The magnetic pole is shifting so briefly that it has compelled the arena’s geomagnetism professionals into a unprecedented transfer. [T]hello are set to replace the World Magnetic Model, which describes the planet’s magnetic box and underlies all trendy navigation, from the programs that steer ships at sea to Google Maps on smartphones. The most up-to-date model of the fashion got here out in 2015 and was once meant to ultimate till 2020 — however the magnetic box is converting so abruptly that researchers have to mend the fashion now.

“The error is increasing all the time,” says Arnaud Chulliat, a geomagnetist on the University of Colorado Boulder and the National Oceanic and Atmospheric Administration’s (NOAA’s) National Centers for Environmental Information…. By early 2018, the World Magnetic Model was once in hassle. Researchers from NOAA and the British Geological Survey in Edinburgh have been doing their annual test of the way neatly the fashion was once shooting all of the diversifications in Earth’s magnetic box. They discovered that it was once so erroneous that it was once about to exceed the appropriate prohibit for navigational mistakes.
Nature’s article was once up to date on January ninth to tell readers that the discharge of the corrected World Magnetic Model, which will have to repair accuracy throughout the finish of 2019, has now been postponed from January 15th to January 30th — “due to the ongoing US government shutdown.”
