Not directly because of climate change no. Some areas will be fairly unaffected or might even improve for human use (eg Siberia).
However it will cause ecosystem collapse which we rely on for food due to too rapid change which nature can't handle, and it will change which areas are viable for human habitation and agriculture. Meaning many many people will have to move.
And of course mass forced migration combined with shrinking resources is a recipe for global war. See how popular migrants are now in many countries, and consider half the world having to migrate to survive. Poor people living in areas that become uninhabitable (and who never caused the problem in the first place) will move to a better place where it's likely the current inhabitants will protest.
And a global war is very likely to lead to extinction with the WMD tech humanity has now.
All we need to do is stop trying to be richer than everyone else and to work together :(

Citation absolutely required. This is not in the IPCC reports, which are already quite extreme in their projections.
The IPCC sixth assessment report has an entire section on ecosystem impacts, and while a number of changes are projected with varying degrees of confidence, the word “collapse” is nowhere to be found, except for the following sentence:
> It is not known at which level of global warming an abrupt permafrost collapse…compared to gradual thaw (Turetsky et al., 2020) would have to be considered an important additional risk.
