Dating back into the late nineteenth century, the data coverage has been dense enough to reveal the existence of gradual changes in hemispheric - and global - mean surface temperature.

«TCR was originally defined as the warming at the time of CO2 doubling (i.e., after 70 years) in a 1 % yr — 1 increasing CO2 experiment (see Hegerl et al., 2007b), but like ECS, it can also be thought of as a generic property of the climate system that determines the global temperature response ΔT to any gradual increase in RF, ΔF, taking place over an approximately 70 - year time scale, normalized by the ratio of the forcing change to the forcing due to doubling CO2, F2 × CO2: TCR = F2 × CO2 ΔT / ΔF»

Most attention in the debate over climate change has been based on the assumption of a gradual increase in mean global temperatures, equilibrating to a new higher level some decades after concentrations of greenhouse gases have stabilized, with effects that will then play out for centuries.
