#2This is one can I'm OK with kicking down the road :-)
(I'm joking; the article is interesting, and I'm not trying to frame it as trying to portray this as an urgent threat)

#4Patently ridiculous to make the assumption that given a billion years, no multicellular photosynthesizing organisms will adapt to the changing environment. A billion years.

Oxygen is a best in class reagent. Lots of pent up energy. You're correct that it's not necessary, but it's going to be tough without it.

#7I can't see the paper [1].
But the code is here: https://github.com/kazumi-ozaki/lifespan/blob/master/main.f9...
It does not give me great confidence in the modeling. Perhaps the paper goes into great detail about the formulas used in the code, and explains those variables and naming choices (those not in the Constants file with comments), or the fitting coefficients.
Of course, I really wonder how the complexity of the natural world could be captured by a few hundred variables.

Get to work on those planet hunting.

#9My impression is that a large amount of what we think as non-biological is in fact the product of life. Making the prediction that life will be unable keep the environment the same despite external factors seems like a bold predication; let's see how it plays out.

#10Earth will not host complex plants in 600 million years. So that’s also a problem - https://en.m.wikipedia.org/wiki/Timeline_of_the_far_future
