TCR
Transient Climate Response (TCR)
TCR is defined as the average global temperature change that would occur if the atmospheric CO2 concentration were increased at 1% per year (compounded) until CO2 doubles at year 70. The TCR is measured in simulations as the average global temperature in a 20-year window centered at year 70 (i.e. years 60 to 80).
