I mean, we have bacteria living off of the heat and gases of underwater volcanoes — it is absolutely not realistic to think that life itself will be in jeopardy. It has survived the release of a highly reactive gas that killed off the majority of things (oxygen), a huge meteor that introduced a huge cooldown overnight, etc.

Of course, it doesn’t mean that we should not try to stop the impending doom that will kill off an insane amount of species, and render many populous places unlivable for humans, causing famine and wars - but Life itself will never be in any danger.

I thought so too at first. But there is no liquid water on Venus. So it is possible for all life on earth to just get boiled off.

The Venus is quite a lot closer to the Sun, though. A few degrees C change in the average temperature of the Earth indeed can cause absolute large changes, potentially killing of most more complex life forms, but even that would be very far off from the point where life is infeasible - especially that the bottom of the ocean won’t be reaching anywhere close to temperatures where proteins denaturate.

Venus gets roughly double the sunlight that earth does, also:

“Conditions possibly favourable for life on Venus have been identified at its cloud layers, with recent research having found indicative, but not convincing, evidence of life on the planet.” https://en.wikipedia.org/wiki/Venus
