Global warming: Melting of Greenland and Antarctica is moving the North and South poles

The video discusses the melting of ice in Greenland and Antarctica, leading to the migration of the geographic North and South Poles. This movement is due to the redistribution of Earth's mass, similar to a skater adjusting their arms. The North Pole moves towards areas losing mass, such as Greenland. Polar motion is also influenced by changes in water storage on continents. Up to 40% of polar movement is due to Greenland's ice loss, 25% to Antarctica's, and another 25% to continental water storage changes. The North Pole, once moving towards Canada, is now shifting towards the UK and Europe at a faster rate.
