As Magnetic North Pole Zooms Toward Siberia, Scientists Update World Magnetic Model (npr.org)

An anonymous reader quotes a report from NPR: Earth's geographic north pole is fixed. But the planet's magnetic north pole -- the north that your compass points toward -- wanders in the direction of Siberia at a rate of more than 34 miles per year. That movement may seem slow, but it has forced scientists to update their model of Earth's magnetic field a year earlier than expected so that navigational services, including map-based phone apps, continue to work accurately. The drift results from processes taking place at the center of the planet. Molten iron and nickel slosh and spin in the planet's core, essentially serving as a metallic conductor for Earth's magnetic field. Changes in that fluid flow lead to changes in the magnetic field. As a result of those changes, the accuracy of the National Oceanic and Atmospheric Administration's World Magnetic Model (WMM) -- a mathematical representation of the magnetic field -- slowly deteriorates in the five-year periods between updates. The next update was due in 2020. But "unplanned variations" have degraded the quality of the WMM so greatly that NOAA published an out-of-cycle update Monday. It was delayed from January by the partial government shutdown.

    Lmao did you see how Bernie just kept shrinking lower and lower in his chair, trying to say there was no way he was owned, he was not owned, he did not get owned, as he shrunk into a corncob

    He'll be the first President to brag about living in the "Big House" instead of the White House. What a fat traitor.

    #Strong, American Rope. Trust in it.

    Sorry, you can't put someone in prison because they hurt your little feefees. Time for you to grow up now.

    Clearly those Russian hackers did this!
    They've been editing the raws for world_configuration.ini
    The evil scoundrels!
    When will someone speak up about this?!
