- As of 2019, the north pole has traveled beyond the Canadian Arctic to 86.448 degrees N 175.346 degrees E. And the south pole is located somewhere 64.28 degrees and 136.59 degrees E, i.e within the Indian ocean in between the Australian Plate and the Antarctic plate.
- As per the reversal, there have been 183 reversals over the last 83 million years, due to the lack of data and variety of estimated there has always been a complex process to locate the wandering poles. And these reversals are considered normal for the planet buy for mankind they pose a threat.
