On January 1, 2026, while the world was celebrating the start of a new year, scientists in Antarctica were busy moving the South Pole. This annual event may seem surprising to many, as we often think of the South Pole as a fixed point on Earth. However, the geographic South Pole is actually located at the southern tip of Earth’s axis in Antarctica. It is important to note that this point does not align with Earth’s magnetic or geomagnetic South Poles, which are constantly shifting due to changes in the planet’s magnetic field.
The task of moving the South Pole marker is necessary because the ice beneath it is constantly flowing at a rate of about 10 meters per year. Although the geographic South Pole itself remains stationary, the marker must be repositioned annually to account for the movement of the ice. This year, the U.S. Amundsen-Scott South Pole Station staff conducted the traditional New Year’s ceremony, complete with a stuffed penguin, bagpipes, and the unveiling of a new marker.
The Antarctic ice sheet acts like a slow-moving frozen river, with ice gradually flowing from the center of the continent towards the sea. Rising ocean temperatures are causing the ice on Antarctica’s coast to melt, potentially destabilizing glaciers and contributing to global sea level rise. It is essential to monitor and study these changes to better understand the impact of climate change on the Antarctic region and beyond.
