This feels like quite the large strawman in TFA. Most of the folks I've talked to in longtermist-adjacent circles (futurists, effective altruists, etc., that crowd) see climate change as a very real existential risk, for the same reason the Bulletin of Atomic Scientists do: it greatly increases the risk of large-scale conflict which could lead to nuclear war. Even if Homo sapiens survives, there's an existential state where we knock our progress so far back, we aren't able to re-bootstrap the industrial revolution, due to depletion of surface-level resources at a scale sufficient to restart industry. So yes, climate change does have the potential to compromise our existence over trillions of years. I think the bigger problem with this movement is the concentration of already-wealthy types amongst its adherents, which skews the overall perspective away from more common plights.
