Ultimately, we'll all realize that there is no such thing as a climate-safe place, only places with different climate-related impacts, unfolding on different timescales, to differently-equipped people, interconnected in ways we can't begin to fathom. Jamie Beck Alexander Project Drawdown
NOAA provided a summary of a study published in the Proceedings of the National Academy of Sciences of the United States of America. In a nutshell, the climate niche where we can survive is called a Goldilocks Zone, neither too hot nor too cold, which continues to move poleward.
Humans, the vast majority of which reside in lower latitudes, will have increased their populations significantly. As a result, there will be a mismatch between a livable climate and distributed people. There will be terrors that we had never had to face before as temperatures conducive to creating civilization as we know it today turn into a dangerous threat.
