Is this an AI generated text? It reads very strange to me though I can't exactly put my finger onto why. For example statements like climate change related sea level rise alone could extinct all of humanity doesn't seem like something a reasonable human would write. Is there any credible climate scientist in the world who thinks this is a real possibility? Hint lots of people would just move away from the rising sea and survive. Anything short of catastrophic impact induced sea level rise of thousands of feet aren't going to extinct all of humanity.
