Maybe my wording conflates unintentionally meaning "extinction of humans" with "extinctions of many species." Extinction of many species is happening at several orders-of-magnitude of background, historical trends. Homo sapiens sapiens extinction outright is unlikely unless we double-down on emissions. Let's call climate change a "Dial-a-yield" planetary nuke that will extinct many species and most likely reduce our numbers anywhere from 1-50 million if nothing is done, e.g., pre-historic levels. We have to make drastic changes now to dial back the "yield." How bad climate change has to be is ultimately up to all people across the world, here and now.
