That is a dick move by the US. Idk how it can be claimed it is not America's responsibility for this mess.

It isn't climate change causing the problem, it is that we haven't found a solution because we aren't looking for one. The tomb was designed to last until we figured out what to do with it, but we started giving money to niggers instead. The tomb is like Chernobyl's sarcophagus - it was never meant to be a permanent solution.
