Get it through your head.
All images of Earth that have been taken from space show no sign of a "Ice Wall". If it did, then we will be able to take a side view of it from space and see that it reaches out to Space.
Another flaw, since there is Global Warming, then wouldn't the wall be melting also with the Ice Caps? It's common since.
Seriously, the guy who came up with this theory and those photoshoped pictures has too much time on his hands. He's a high schooler, he dosn't know shit compared to the government scientists that are still studying the world that we inhabit, Earth.
Earth is round. It has a diameter of 7,926.41 miles from the Equator. Continents move, it's called Continental Drift. Animals adapt to their surroundings. Oh, I bet you all didn't know this, ALL fucking planets are round.
It surprises me to see how meny people here believe this shit.
EDIT : Oh, and if you climbed the supposed Ice Wall to the boundary of Earth's atmosphere, you would die instantly.
