I just had a lightbulb moment.
Atlantis is under Antarctica.
Explains why no one is allowed there. Explains the ice wall. Explains why they don't want the ice uncovering it and are spouting the fake climate change narrative, and why they want to cool the earth down to a ridiculously low level where human and plant life will not be able to exist. I just did a search online, and first website I open says that other scientists, including Einstein, believe(d) it to be Atlantis. The amazing power source they had will still exist under the ice.
