Kerry thinks flat earthers believe melting of ice will lead to water pouring over the edge of a flat earth. He has the model wrong because there's an ice wall that assures that, if ice melted, that water would rise in the flat earth bowl. He's ostensibly going to Antarctica to check the damage from global warming.
I ran across Jungle Surfer's analysis of the fakery of Antarctica's research stations several months ago-- possibly a year ago in mid 2015 but didn't want to admit that this could be possible since it would simply annihalate my current effort to measure the distance between the stations... and cumulatively figure on proving 60,000 or 15,000 miles as a circumference, thereby proving flat or spherical earth. However, after reviewing his work again, I think I have to at least consider the possibility that the stations, along with many of the other elements of Antarctica-- like fake solo crossings and the fake Vendee sailboat race-- might indeed be fake. Here's his flagship video on this topic.
