Scientists propose building artificial walls to save Antarctic glaciers from collapsing

The video discusses the rapid melting of the world's ice sheets, which is causing sea levels to rise. To combat this, scientists propose constructing artificial undersea mounds to help reground the ice. Another idea is to build a continuous wall or sill to block warm water currents from thinning ice shelves.

What is the primary consequence of the rapid melting of ice sheets?

• Decrease in global temperatures

• Rise in sea levels

• Increase in polar bear population

• Expansion of ice sheets

What is the purpose of constructing artificial undersea mounds?

• To create new habitats for marine life

• To increase fish population

• To catch and reground flowing ice

• To generate hydroelectric power

How do artificial undersea mounds help in mitigating ice sheet melting?

• By reflecting sunlight

• By catching ice and allowing it to reground

• By absorbing carbon dioxide

• By increasing ocean salinity

What is the proposed solution to prevent warm water from thinning ice shelves?

• Enhancing ice sheet albedo

• Reducing global temperatures

• Increasing ice sheet thickness

• Building a continuous wall or sill

What is the main threat posed by warm water currents to ice shelves?

• They decrease sea levels

• They increase ice shelf thickness

• They cause ice shelves to expand

• They thin the ice shelves
