As conditions that best support life shift toward the poles, more than 600 million people are already living outside of a crucial “climate niche,” facing more extreme heat, rising food scarcity and higher death rates.
If it pushes us out of the most livable areas, what's it doing to populations in fringe areas? Seems like most of humanity may be a bit inconvenienced. Also, the problem is more than just the heat, as we can't just pick up crop areas and shift them northward. Factors like weather patterns, water, soil, and other things make it a bigger issue than living where it's not as hot.
