I'm not sure I get why everything above France would be rendered uninhabitable? The coldest place inhabited by humans year round is Oymyakon https://en.wikipedia.org/wiki/Oymyakon

Temperatures are generally above 0°C in summer, -50 approximately in winter.

Will an Ice Age actually be worse than that?

I would expect somewhat better, although maybe not much. I might expect Denmark and Southern Parts of Sweden and England to reach 10 degrees in Summer, and -20 in Winter. But that is of course just a guess on my part so I am certainly willing to hear that I have guessed wrong.

If the Earth's atmosphere gradually disappeared over the next 10-50 years would that be okay because humans live in the ISS?

Last ice age had a km thick ice sheet going down to Berlin.

Yeah but I would think that is still survivable, unless it comes like that one dumb movie in which the ice age is a super quick one and everything happens in the space of 24 hours approximately.

Of course I'm thinking survivable with the magic of "technology" and maybe I'm adding wishful thinking into this science fiction scenario here, but I'm not sure if the result of the new Ice Age will be the same as the last one.

Survivable is a strong word. We can survive for a long time huddled around breeder reactors. IMO the better question is how many of the affected people would try to migrate to better areas and how much firepower they bring with them when they’re not welcome.

You'd need to pull habitations up by a couple meters each year for a few decades if that one km of ice sheet builds up gradually :D Probably survivable, but inside yurts instead of fully furnished flats with amenities.
