Transient Climate Response¶
The transient climate response (TCR) is defined as the global and annual mean surface air temperature anomaly in the 1pctCO2 scenario (1% CO2 increase per year) for a 20 year period centered at the time of CO2 doubling, i.e. using the years 61 to 80 after the start of the simulation. We calculate the temperature anomaly by subtracting a linear fit of the piControl run for all 140 years of the 1pctCO2 experiment prior to the TCR calculation (see Gregory and Forster, 2008).
