The ledger is warming. Here are the receipts.

Six charts, one story: emissions concentrate, heat accumulates, ice retreats. Switch datasets to re-ink every bar — all rendering is inline SVG and divs, no chart library.

Illustrative proportions styled as a ledger; values re-ink when you switch tabs.

Where the heat goes

Share of excess energy, 1971–2025
Ocean 91%
Land + ice 9%
Atmosphere ~1%

The ocean absorbs the overwhelming share — marine heatwaves are the receipt.

Sea-level rise

+21 cm

Since 1900, from tide gauges and altimetry. Rate has doubled since 2006.

Renewables share

30%

Of global electricity in 2024. Drag nothing — press below to project.

Days over 35°C

×3

Tropical cities now average triple the extreme-heat days of 1980.

Reading the ledger honestly

Demo values are illustrative, not observations. The interaction patterns, however, are production-grade.

One engine

Bars, decades and ice share a renderer. Switching datasets only re-inks heights and labels.

Isolation

Clicking dims siblings to 25% opacity. Click again to restore the full ledger.

Projection

The 2030 counter ticks 30 to 42 on an interval. Watch, then verify against your own grid.

Keyboard: 1–3 switch datasets, R replays the draw.

Method note

Gauge dashoffset and donut dasharray are the only SVG tricks. Everything else is divs.

Offline note

Double-click to open. No chart library, no webfont, no network calls.

Ledger colophon — 025

Inked, isolated and projected in one file. Rulings from the ledger desk.

BARS

One renderer, three datasets. Click dims siblings to a quarter.

GAUGE

Dashoffset needle on a 283-unit arc. Paris line at 1.5.

DONUT

Ocean 91, land and ice the rest. Two buttons reshape it.

Keys 1–3 swap data, R replays. Projection ticks 30 to 42.

Value honesty

Illustrative proportions. Patterns transfer to real observations.

Offline ledger
