开云体育It's hard to find current data, but the movement of the poles has been speeding up.? You can see it some from 1980 to 2015 but it's moved quite a bit in 10 years.? The south pole is headed for the Indian Ocean.? Also the strength has been dropping which can cause instability in a compass.Getting current data is again not easy.? Some sources have the rate of decrease accelerating past this chart. On 28-Feb-25 7:49, davesmith1800 wrote:
