"Almost a billion years ago" in the first sentence to "Over half a billion years ago" a few minutes after the post went up based on this email from Green Gabbro:
These rift structures are Late Precambrian and Early Cambrian - ~500-600 million years ago, not really "almost a billion". They’re probably associated with later stages of Rodinia’s breakup.

What blows my mind it that Scotland and North America are related. Warmest regards, Doc.

I only have to hang around for about a million years or so to see the Mediterranean close up. Hell, Mickey Rooney is, what, five- or six-hundred thousand years old?

That's not quite enough time to redeposit the excess CO2 - might be a fun ride climate-wise!

It will just be the time for dinosaurs again. Of course, I'm assuming their lung structures resemble their modern ancestors, the birds. Their breathing apparatus is much more efficient than our clumsy mammalian system. Perhaps they shouldn't have planted all of those trees back in the day and allowed the mammals to gain a foothold.

We don't have to worry about turning Earth into Venus through burning fossil fuels alone. While Venus has about as much carbon as Earth, it doesn't have enough water to cause it to form limestone continents like Earth. So Venus carries all of its carbon in it's atmosphere in the form of carbon dioxide, which is why its atmosphere is so freaking dense, while most of Earth's carbon goes into making up the ground on which we stand. Even if we burned through all of Earth's oil and coal, it probably wouldn't more than double carbon dioxide concentrations from what they are now. While the resultant global warming would make the planet uncomfortable, it wouldn't make it unlivable. After all, we'd only be releasing that portion of carbon that was stored during the Carboniferous Period, a minute fraction of the total amount of Earth's carbon stores. That is, until someone figures out how to burn calcium carbonate.

paleoclimatology says that CO2 levels have been much higher for much of the span of metazoic life:

pretty good evidence that going the way of Venus isn't a concern, "just" changes to species balance and our lives as a side effect.

Pretty lucky our unique specialization, the use of socially significant symbols to mediate our interactions with the world and each other, enables us to discover and co-opt the survival strategies of any other form of life on the planet, making us the most adaptable species to have ever evolved. We're the only species that can survive in the vacuum of space, the intense pressures of the deep sea, the freezing cold of Antarctica, and the blazing heat near an active and erupting volcano. True, we need technology to do all that, but still, we can do it. It gives me hope that no matter how short-sighted we are, we won't actually be able to destroy ourselves and that we stand a chance of attaining our collective destiny.

who exactly will be included in the "we" who get to leave descendants beyond the looming crises and bottlenecks.
Much of the sociopathic behavior I see in economies and nations these days has looked far to much like survivalism than ordinary greed, for my comfort.

So natural selection and heartless Darwinism still has a great deal to say about who gets to pass on their genes, and who doesn't. We won't be able to ensure the fitness of the least-advantaged of our species until we perfect morality, which won't occur until we perfect technology, which won't occur until we perfect science. If it makes you feel better, at least we've evolved enough to feel bad about it, and begin to do something about it.

think that this might be the forth one. Warmest regards, Doc.

or perhaps, fourth.
