Building a different kind of wall
A team of engineers might have an idea to slow rising seas and collapsing ice sheets. They have proposed building a giant wall in the sea to support some of the most vulnerable ice sheets in Antarctica. This could be the largest civil engineering project ever attempted. It’d be a huge undertaking… but we’re on thin ice.
