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.

What is the primary reason for the migration of the geographic poles?

• The rotation of the Earth

• Redistribution of the Earth's mass

• Solar flares

• Gravitational pull from the moon

How does the loss of mass in Greenland affect the North Pole?

• The North Pole moves towards Antarctica

• The North Pole moves away from Greenland

• The North Pole remains stationary

• The North Pole moves towards Greenland

What percentage of polar movement is influenced by changes in water storage on continents?

• 50%

• 10%

• 40%

• 25%

Before 2000, towards which country was the North Pole moving?

• Canada

• United Kingdom

• Greenland

• Russia

At what speed is the North Pole currently moving towards the UK and Europe?

• 25 centimeters per year

• 8 centimeters per year

• 12 centimeters per year

• 18 centimeters per year
