How small could this unit be? Cybercurrencies need liquidity at all scales of transaction, so a conservative denomination process might emulate the SIU system by defining the quantum limit of model sensitivity , and creating a scalar analog of Plank's Constant for planetary modeling.
With real world temperatures rising at rates of nanodegrees per second this quantity- let us call it Arrhenius's Constant, ( 'Å' ) might be comfortably scaled in analogy to Planck's constant, to be around one over 10 to the 45 ˚K per cubic Meter.
This would be consilliant with human comfort , since people are about 2 meters long, and can hardly differentiate microclimates on smaller scales, as it is hard to establish room temperature if you simultaneously feel that your head is warm and your feet are cold.
Once Å has been established, M scale modeling can commence, and the translation of Arrennius scale pixels into NFT's will self-defines economic climate sensitivity by entangling climate modeling and crypto mining at the limit of quantum sensitivity
This Å-list cryptocurrency should be immune to hyperinflation, as the number of unit coins is denominated the object modeled, and the Earths surface area is a paltry 508,000,000,000,000 square Å. In praxis this may enable every smartphone owner to mine their own climate, as billions of crypto subscribers will only have to micromanage the microclimate of a few hundred kilopixels of surface
