What is the 1pctCO2 experiment?
CO2 rises by 1% every year until it has quadrupled — a clean, gradual ramp used to measure how fast the climate warms.

What is the 1pctCO2-bgc experiment?
The same 1%-a-year CO2 ramp, but only the carbon cycle 'sees' it — isolating how much carbon the land and ocean soak up.

What is the 1pctCO2-rad experiment?
The 1%-a-year CO2 ramp is felt only by the radiation code — isolating how a warming climate weakens natural carbon sinks.
4 July 2026 · Charles Turner, ACCESS-NRI
What is the abrupt-4xCO2 experiment?
A deliberately extreme idealised run: quadruple the CO2 instantly and watch how the climate responds.

What is the historical experiment?
The historical run recreates the climate of 1850 to the present using our best estimate of what actually drove it.

What is the piControl experiment?
A long, stable simulation of a pre-industrial world that acts as the quiet baseline for every other run.
