(Groan) Well, maybe if J is a carbon cycle capacity it can be scarce. But are you implying that it cannot grow?
On the data? Even if it were growing, it’s not keeping up. It’s far more likely shrinking than growing, and really, all we need know for scarcity is that there is a limit, not its nature. The nature of the limits would be an issue of management and administration, which we’re just not there yet.
, and it is rivalrous Only if the capacity of the carbon cycle must be rationed and not grown.
If you’re proposing a geoengineering plan to grow the carbon cycle capacity, that’s also an interesting question.
It’s entirely possible that simple botanical selection of deeper-rooting, or more root-mass concentrating plants and subsoil microbes _could_ expand the capacity of the carbon cycle up to sequestration limits.
Of course, then eventually we get to the hard geological limits of how fast we can precipitate carbon out of the biosphere and turn it into rocks. It appears to me that rate is pretty much fixed, and no one’s proposing a scheme to increase the rate would be cost effective.
And that brings us back to square one where we must believe either
(1) a bunch of big government kleptocrats armed with buggy computer models with insufficient data who tell us high CO2 will mean the end of life as we know it and that handing over our freedom and treasure will solve that sky-is-falling problem, or
Unless we let the Market decide by privatizing and pricing the carbon cycle, just like every other rivalrous excludable resource with capacity limits.
(2) the Rocks — Which tell us, “Been there before. What problem?”, or
When we were there before, the planet could sustain perhaps 40% as much biomass as it appears to at a stable peak of 280 ppmv CO2.
(3) the Plants — who collectively say, “Good! the CO2 drought is over!”
Except CO2 has been as low as 180 ppmv. The drought is in fixed nitrogen, which raising CO2 levels just makes worse.
