Massive ‘Doomsday Glacier’ could collapse into ocean

The Thwaites Glacier, known as the Doomsday Glacier, is melting faster than expected, potentially raising global sea levels by up to 65 centimeters. With a size comparable to Britain, its melting is alarming due to warm water currents reaching its base, threatening its stability. Data from the uncrewed submarine Ran reveals that these currents are eroding the glacier's anchoring ice pillars, risking large ice sections breaking off into the ocean, accelerating melting and increasing sea levels.

What is the potential impact of the Thwaites Glacier on global sea levels?

• It could raise global sea levels by up to 65 centimeters.

• It could lower sea levels by 65 centimeters.

• It has no impact on sea levels.

• It could raise sea levels by 10 meters.

Why is the Thwaites Glacier referred to as the 'Doomsday Glacier'?

• Because it is melting slower than expected.

• Due to its potential to significantly raise sea levels.

• Due to its location in Antarctica.

• Because it is the largest glacier in the world.

What role did the submarine Ran play in studying the glacier?

• It transported scientists to the glacier.

• It collected data by traveling under the glacier.

• It melted the ice to study the glacier.

• It built a base on the glacier.

What alarming discovery did the submarine make about the glacier?

• The glacier is growing in size.

• Warm water currents are reaching the glacier's base.

• The glacier is completely stable.

• The glacier is moving towards the equator.

What could happen if the ice pillars at the glacier's base collapse?

• The glacier would move inland.

• The glacier would freeze completely.

• Large areas of ice could break off into the ocean.

• The glacier would stop melting.
