Long name: 1 percent per year increase in CO2 Simulation years: 1-120

Description: Increase atmospheric CO2 concentration gradually at a rate of 1 percent per year. The concentration of atmospheric carbon dioxide is increased from the global annual mean 1850 value until quadrupling.

Rationale: Serves as a consistent and useful benchmark for analysing model transient climate response (TCR). The TCR takes into account the rate of ocean heat uptake which governs the pace of all time-evolving climate change. In Earth System Models (ESMs) that include explicit representation of the carbon cycle this experiment allows the calculation of the transient climate response to cumulative carbon emissions (TCRE) to be calculated.
