    Just in case it wasn’t clear, that’s a horrifying discovery. Like the extinction of all life on earth.

    Hopefully enough things can adapt in time and then something can give it another go

      FWIW, the Earth has about 500-600My left before common photosynthesis is no longer possible, due to consequences of Sol (our sun) relentlessly heating up, gradually.

      Now personally, my understanding is that unless complex life somehow adapts, then that will be the end of such upon Earth, with simpler life presumably surviving for billions more years past that mark.

      Point is-- if complex life can survive the coming collapse, then it evidently does have a very nice, healthy window to work with. Personally, I suppose that might be helped out quite a bit by the ‘churning of the continents,’ in which landmass gets regularly cycled back in to the magma layer over the course of millions of years, with new areas appearing on the other edges, so to speak.

      EDIT: clarifications

        But billionaires need bigger yachts. And more mansions. What’re we to do? Can’t sacrifice the billionaires ultra-mega-yachts.

                          Ahh, good point, yes.
                          I actually was thinking about those beautiful little deep-sea worlds when I wrote the above, but simply didn’t know enough to assert a dang-ol’ thing at the time. Okay, let’s see:

                          However, although it is often said that these communities exist independently of the sun, some of the organisms are actually dependent upon oxygen produced by photosynthetic organisms, while others are anaerobic. –WP

                          So… looks like we have at least *some* members of these little communities carrying on, past the death of oxygenic photosynthesis, which they evidently don’t need in order to survive. (meanwhile with anoxygenic photosynthesis carrying on for many millions more of years).

                          But off the top of my empty coconut, it does raise a couple Q’s:

                          1. Since there are maybe a dozen or less community members who live in these little worlds, closely built in to a commensurate ecosystem, would the death of the ones who rely on traditional photosynthesis bring about a collapse, either partial or total?

                          2. Would rampant global warming tend to mess with the already super-heated, typically sulfurous nature of these worlds? (me, I would tend to think “nawt,” since they’re already so hot, but then again, I’m just some layperson really curious about all this, hah)

                          Ah… those beautiful, entrancing little forbidden worlds:

                              at this point I’m fully expecting the only thing that keeps us from extincting ourselves with global warming is almost extincting ourselves with nuclear winter.

                                  I don’t wish for this to happen, mind you, but we are clearly living in the dumbest possible timeline, and so it is the only solution that makes sense

                                        Also due to reduced water vapor and ice cover lol. It’s a conclusion that can be drawn without much reliance on the article, which focuses a lot on specific climate model improvements and not the obvious concern: given our desire for the earth to reflect more of the sun’s rays and cool off, reflecting fewer and warming up is not good
