We present a carbon-cycle–climate modelling framework using model emulation. designed for integrated assessment modelling. which introduces a new emulator of the carbon cycle (GENIEem). We demonstrate that GENIEem successfully reproduces the CO2 concentrations of the Representative Concentration Pathways when forced with the corresponding CO2 emissions and non-CO2 forcing. https://thebrickes.shop/product-category/turntable/
