Aggregation is weird, when talking about morality. I don’t know what you mean by “all life on earth” or “of humanity” in this context. Which humans have what duty to exactly what? Are you concerned with biodiversity, biomass, variety or quantity of mammalian brains, or something else?
I expect that climate change will be an extinction event for many plant and animal species, and climate change or not, all individuals will die eventually. However, it won’t overall destroy all life on earth—we’ll engineer mitigations for large numbers of humans, and that will carry along with it large numbers of species and individual animals. It’ll be painful and expensive, but not permanent destruction of life.
Unless the rioting and civilizational fragility keeps us from mitigating it, and we nuke ourselves in the process. That could set things back a few tens of millions of years.
