...there have been at least five occasions throughout history where the human race has been in danger of dying out, not least because of the eruption of a supervolcano 70,000 years ago that almost sent us the same way as the dinosaurs.
So when will our species go extinct? If you're an optimist, it won't be for another billion years. That is when the expanding sun will cause our planet to heart up to a Venus-like state and render all life on Earth extinct.

Obviously.
Or pushing Putin over the edge and starting the 'final solution'.
Mostly inaccurate as its all guesstimates based on populations in Africa an Europe. The data likely did not count populations in the Americas, India or China
I’m thinking it will involve cell phones.
"The car in the movie is a real GT350H, that is now signed by Carroll Shelby, Steven Spielberg, and Tom Cruise."
What do you say that? I watched a discussion of this recently. I’d be interested in what your serious objections to it are.
“ I’d be interested in what your serious objections to it are.”
Well, to me the very idea is ridiculous. How could that possibly be known? Even if you took what we imagine today’s population to be and did a lot of fancy math to end up with such an accurate number from that long ago is difficult to accept. There was no census. There were no records of anything except various layers of sediment. 1200 breeding pairs in the whole world? That is a stretch. I guess to me it just sounds farcical. I am not a scientist, so this could be an elementary fact. I doubt it though.
I am going to guess that not a single one of those was because of “warming”
The NeoCons are working on this project. They are psychos who will get us all killed.
Nah, I saw it on star trek once, or superman....ahhh,I can’t remember which.
I don’t have the time to watch the discussion...but here would be my objections...ahem...
Too many factors involved in population growth model. Assume a known amount and extent of unperturbed reproduction cycles. Assume length of generation in years. 15 years, 20 years, ?. Assume a uniformitarian model of earth history. Assume the extent of geological and/or meteorological effects on generation cycle time. Assume number of progeny per generation. Assume exact number of famine, diseases, predation, privation, war, murder events and their effects on population growth. Based on those consideration, I would guess the number of reproducing units was 1354...IMHO.
I am not a scientist either, but I share your skepticism.
All they can measure is how fast the population accelerated in modern times, when there is little to deter it. A bit of war, famine, plague, genocide, abortion, etc., in recent times.. other than that, mathematicians could measure the rate of population acceleration absent any extinction level event.
Then, divide 8 billion by that rate of acceleration, and calculate how long ago the number would be zero. That’s probably where they got the first near extinction ‘data’ point.
Beyond that, it would have to be pure conjecture.
Ironically, it will be the people portending the demise of humans that bring it about - scientists.
Repeatedly “almost” going extinct is precisely why humans no longer resemble lesser primates. Our species is built on repeatedly almost going expense, complete with chemical pathways to introduce pathogens through the digestive system and exogenate the pathogens into our DNA.
This species has amused itself to death.
Activity near Mammoth Lake ,Calif is interesting
Too young or too old
Once on a star, in a remote corner of the universe, some clever animals invented knowledge. But then the star grew cold, and the clever animals had to die.
One might invent such a fable, but still not sufficiently have illustrated how shadowy and flighty, how aimless and arbitrary, the human intellect appears in nature. There have been eternities when it did not exist, and when it is gone, nothing will have happened.
