The most dire prediction can be read in the following article: https://www.cnn.com/2023/09/26/world/supercontinent-earth-intl-scli-climate-scn/index.html
After re-reading that article , well reading it all the way through really for the first time , I agree that was sloppy journalism on CNN's part. I should've found a better & credible source for that information for the link in my OP.
At any rate, 250M years is enough time for climate to correct from our shenanigans, so adapt or die, mammals
