Up here, carbon is a vapor with manners — CO&sub2; in vanishing concentrations, drifting like rumor between continents.

the invisible architecture of carbon
+ 01 / The Bond
Carbon is the patient diplomat of the periodic table — four valences, no ego, willing to share with almost anyone. From this quiet generosity comes the long architecture of life.
It links to oxygen and becomes breath. It links to hydrogen and becomes sugar. It links to itself and becomes the spine of every molecule that has ever moved on its own.
Beneath the dreaminess of golden afternoons lies this ledger of bonds — a Swiss grid of obligations and exchanges, drawn in ruled lines across the surface of every leaf.

+ 02 / The Cycle
Up here, carbon is a vapor with manners — CO&sub2; in vanishing concentrations, drifting like rumor between continents.
~420 ppm · troposphere
A leaf opens its stomata. Light arrives. Water rises. Carbon is invited inside and quietly rearranged into sugar — a small, illegible miracle.
6CO&sub2; + 6H&sub2;O → C₆H₁₂O₆ + 6O&sub2;
What was leaf becomes litter. What was litter becomes humus. Microbes negotiate with carbon, breaking its bonds and brokering its return.
~1500 Pg C · soil organic carbon pool
Half the carbon we exhale is folded into the sea, a slow gray cathedral that buffers and remembers, dissolving stone and growing shells.
~38000 Pg C · deep marine reservoir
Through fire, breath, decay, and industry, carbon returns to the air — a debt repaid, a ledger balanced, a wheel that does not stop turning.
~10 Pg C / yr · anthropogenic flux
+ 03 / The Return
Order returns. The grid snaps back. The river is recorded in tidy columns of numerals, and the dream is, briefly, a measurement.
