Came across a video on Rumble, which of course doesn't provide any sauce, but doing a quick Bing search provides one matching result which of course is the top result and appears to be by a "fact checker"
Eye's on, something may be breaking on Antarctica...

TL:DR- Russia may be thinking about making a formal land, or mineral claim to parts of Antarctica, possibly violating treaty. But, no land claims have been made yet.
Hopefully that's not the case. I'd love to see some light shed on what's exactly going on in Antarctica but would hate to see it overrun by people raping, pillaging, and plundering potentially a "New World".
