With what? You don't know what's gonna be there. None of us do. And you're acting like cold is the only problem we'll have in the tundra.

[Plenty of weird bacteria and ancient viruses get trapped in ice, too. All it takes is one idiot licking a glacier to pass something along. Preparing for things has never been Nate's strong point, but even he can see the glaringly large hole in this argument.]

I get that you're aiming for an Eagle Scout approach here, but asking the entire population to train their bodies for both sub-zero climates and ninety-percent humidity in this time frame is a tall ask. Some people probably can't handle one or the other, even with help.
