@MichaelEMann @chrisnelder straddling the Equator, & the Sun's luminosity has increased by ~5%, it will be too hot on Earth for land-dwelling mammalian life, including ourselves - but perhaps, by then, our remote descendants will have left Earth for the stars, providing we can survive THIS century, & in that, the threats don't just come from climate change, but the possibility of nuclear war, biodiversity loss, over-population, AI & sheer stupidity. Can we overcome them? That remains to be seen.
