If we destroy the environment, nature will survive - some spiecies will die off, but new ones will emerge.
Nature was doing very well when co2 was a few times more than today. It’s just humans that were’t there to witness it.
Personally, I care about Earth's biome in its current state, and do not want to cause unnecessary suffering to animals or plant ecosystems because people trashed the joint especially since we had the ability not to.
Maybe to you. I derive a great enjoyment from just being alive myself and living my own potential. Considering a life meaningless without procreation is a very unintellectual perspective in my opinion.
So, yes, I know it will survive.
From the announcement you read only the parts how Venus and Earth are similar, but not how they differ. The runaway effect was possible because Venus had less water, is closer to the Sun, and has no magnetic shield. The runaway effect you imagine on Earth needs significant changes in its chemical composition, in its mass, or its physical attributes like magnetic field and thermal input. Humanity is still far from doing something like that. Weight until we start building a cosmic mirror, have self-sustained nuclear reaction on a global scale, or build an earth spanning superconductor network with massive energy volume that would counter the magnetosphere.
