The full height is 1,849 Gt; 2024’s estimate is 38.6 Gt. Early gaps are smaller than the fixed ink lines. Land-use change is excluded. The initial red line marks 2024; selecting a year moves the highlight.
Arrows step years; Shift steps decades. Home/End goes to 1750/2024. Reduced motion skips the reveal.
