At some point the levels of CO2 in the atmosphere will irreparably drop below plant starvation levels, then humans on Earth will go extinct. Even if not, at some point the atmosphere will thin too much, then humans on Earth will go extinct. Even if not, at some point the Sun will go red giant, and then for sure humans on Earth will go extinct.

Of course, all creatures will eventually. I just meant in the next 10,000 years.

  At the rate at which CO2 is disappearing from the atmosphere -or rather at the rate it was disappearing before the Industrial Revolution- we might only have one or two million years left. That's rather soon. The IR may well have added millions of years to the remaining lifetime of photosynthetic and aerobic life on Earth.

    Well, even if that's the case, I don't think it's a big loss. All things live and die, and our time will come too.

      So why not right now then? What number of years or days or hours would concern you? Are you not concerned about other life besides human life on Earth?

        Of course, I want to protect nonhuman life with all my heart. I just don't think it's a big deal if humans go extinct in some thousands or millions of years. I feel much differently about nonhuman life. From the perspective of nonhuman life, we are a disease.

        If we're a disease, don't you want to exterminate us? But then, if all other life is so much better than human life, and if by adding 220ppm of CO2 we extended the time left for that life on Earth by a few million years, didn't our intervention save non-human life from a worse fate[0] than merely having to deal with us? So we can be both, disease and cure. [0] All life on Earth will go extinct eventually, but if we've added a few million years to its story so far, and we could add more millions later, then maybe saying we've "saved" that life is fair.
