r/worldnews - More than 3bn could live in extreme heat by 2070 | Unless greenhouse gas emissions fall, large numbers of people will experience average temperatures hotter than 29C. This is considered outside the climate "niche" in which humans have thrived for the past 6,000 years.

This is incredibly important research that will affect billions of people. Even if you live outside the zones of extreme heat, you could be impacted by vastly increased mass migration.
