A concept that attempts to describe what would happen to global temperatures if CO₂ concentrations...

The concept described isclimate sensitivity, formally defined as the change in Earth's surface temperature resulting from adoubling of atmospheric CO₂compared to pre-industrial levels. This encompassesequilibrium climate sensitivity(long-term warming after all feedback loops settle) andtransient climate response(shorter-term warming before full equilibrium). While transient climate response is a specific short-term measure, the broader principle of warming after CO₂ doubling is referred to as climate sensitivity.
