The robust carbon intensity of global primary energy

[Iterate]

5. I don't see any states in decay or collapse until you get below 1.5 or so Mtons per capita.

Argentina, Chile, Lithuania...all currently at about 4.0. Even Cuba at 2.1 or so for 50 years can't be said to be in a state of collapse, but it does suggest a level at which improvement is difficult.

In fact, it's the children of the British empire who seem to have the biggest problem with high numbers. All of that suggests to me that there is a strong cultural/ consumption and economic structure component to the puzzle.

But...that wasn't the point I was originally trying to make. Simply, if the minimum amount of CO2 currently necessary for life and transition is an order of magnitude higher than the the point at which we reach the Wasdell described tipping points and runaway heating, then you are correct and we are well and truly fucked. Then it's time to invest effort in personalized time capsules and dry desert caves.

If it's not, or if the numbers are close, or if the number has not already passed, well then, the greedy, the clueless, the footdraggers, the deniers are, as Wasdell put it, guilty of a crime against life itself. That knowledge may not matter in the long run, I know.

Here is Wasdell with a bit more passion in his voice. The summary starts at about 6:00.
