Introducing 'freedom gas' – a bit like the 2003 deep-fried potato variety, only even worse for you

Re: Sleep is a Good Thing(TM)

How else do you explain why the extremely high levels of CO2 identified tens of thousands of years ago, far higher than today's concentrations, did not result in an irreversible climate catastrophe?

Something wonderful happened! Or just one of those little mysteries that a carbon-dominated climate can't easily explain. Like where did all the old stuff go, and how do you make an Ice Age? Milankovitch cycles are the usual meme, but effect exceeds cause. It needs some mechanism to create a massive draw-down in CO2 levels to create the cooling showed in fossil records, or our orbit taking quite an excursion for no apparent reason to get energy levels down.
