The Earth Midnight Clock

It is 4.6 minutes to midnight.

"Midnight" is the moment we exhaust the remaining carbon budget for 1.5 °C — the warming guardrail the world agreed not to cross. One remaining year of budget = one minute on this face. Move the slider to see how our choices push midnight away — or pull it closer.

Presets assume everyone on Earth emits at that per-capita level. The budget already spent is locked in; only emissions from here on move the clock.

We still emit about 41.6 Gt of CO₂ a year. On our current trajectory the 1.5 °C budget runs out around 2031 — but that number is ours to change. This is arithmetic, not prophecy.
