Why did Inuit people decide to go and live in such harsh climates? Why would anyone migrate into a more hostile environment?

hi! There was a very similar question a few months ago. New/additional information is very welcome, but meanwhile, check out previous responses (including links to several more related threads) regarding Inuit specifically and northern people in general

For what reasons did the ancestors of the Inuit choose to settle in such climates, rather than returning South?
