I don't think it is the greatest filter, I have no idea what that might be.
But I absolutely agree that civilisations boiling or suffocating themselves out of existence, most likely through carbon dioxide, is a much greater filter than nuclear war or hostile extraterrestrials. Just look at Venus. If we have runaway, I just hope we might survive by darkening the skies, lowering our albedo. That hopefully seems like a survival (whatever that means in the context) strategy once chlorophyll fails us.
- antisthenes 10y agoWouldn't darkening the skies raise albedo? Ideally we want more of the planet covered in snow, or, if that's not possible, deserts.

I probably should have said "reduce the amount of sunlight reaching us", i.e. make the place less bright from our perspective instead of "lowering our albedo", which is the opposite of the relevant outside view.
