On a purely technical basis that may seem reasonable.

On a "we're talking about human beings here" basis what do you do about all the people who feel that the selection and admission process was corrupt and that they've been robbed of their chance at safety? Do you expect them to meekly acquiesce?

I imagine once the first big wave where a nation hits the wetbulb temperature and there is a mass die off you will see panic in surrounding nations and they will scramble to a border. What will nations do with millions of people knocking at the fence wanting in? Uncertain times for sure.

I imagine this happening only in the least well-run countries. In any country with a functioning military, they'll probably organize a mass operation of moving people into temporary refugee camps in cooler areas of the country or into caves, underground structures etc. For people who won't be moved, they'll provide food and water for them so that people don't need to leave their hiding places during the day. (Also, I suspect that, after first major killer heat wave hits an area, people will have their own contingency strategies - be it digging a cellar for themselves to stay in, move to relatives in cooler areas for the duration etc.). However, I'm not sure if for example India is organized enough to pull this off, given their absolutely massive population.

The countries that will be most affected generally don't have well-run militaries either. We're talking about places like Bangladesh and El Salvador.

It’s going to be a global scale “north versus south” war like in South Park—everyone will blame Canada… and Satan will… err never mind. :)

I'm always a little surprised the islands in the Canadian archipelago never seem to be sold.
