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.
