The "Doomsday Glacier" in Antarctica is reportedly melting at a rapid pace, with some outlets suggesting it could lead to significant global sea level rise and potentially catastrophic flooding. There is discussion about a proposed wall, with varying reports on its length, to potentially stop or slow the glacier's impact. The consequences of the glacier's disintegration could have major effects on the globe, including the potential for tens of millions of people to be affected and some US cities to go underwater.
