Climate sensitivity (for a doubled CO2)
= equilibrium temperature change on the surface of the earth caused by this CO2 (or equivalent GHG) forcing.
climate sensitivity
= equilibrium temperature change for doubled atmospheric CO2 concentration

(
change in forcing from bottom to top of a layer
= forcing of that layer;
equilibrium temperature response of a layer
changes the LW and convective fluxes to restore balance).
«Radiative forcing [RF] can be related through a linear relationship to the global mean
equilibrium temperature change at the surface (delta Ts): delta Ts
= lambda * RF, where lambda is the climate sensitivity parameter (e.g., Ramaswamy et al., 2001).
(ppm) Year of Peak Emissions Percent

temperature increase above pre-industrial at
equilibrium, using «best estimate» climate sensitivity CO 2 concentration at stabilization (2010
= 388 ppm) CO 2 - eq.
This was my mental equation dF
= dH / dt + lambda * dT where dF is the forcing
change over a given period (1955 - 2010), dH / dt is the rate of
change of ocean heat content, and dT is the surface
temperature change in the same period, with lambda being the
equilibrium sensitivity parameter, so the last term is the Planck response to balance the forcing in the absence of ocean storage
changes.
«Radiative forcing can be related through a linear relationship to the global mean
equilibrium temperature change at the surface (ΔTs): ΔTs
= λ RF, where λ is the climate sensitivity parameter (e.g., Ramaswamy et al., 2001).»
According to the relationship (dCO2 / dt
= f (Ta)-RRB-,
temperature determines the «
equilibrium»
change in atmospheric CO2, not the absolute level.
Therefore,
changes in density N of total air are governed by hydrostatic
equilibrium condition dp / dz
= - ρ g
= - NM g. Using the hydrostatic
equilibrium and the ideal gas law you can easily express the reference term γ ∂ N / ∂ z via g and
temperature.
If the sea level response to a
change in
temperature is an exponential decay to
equilibrium then given that the 0.8 C
temperature increase since pre-industrial times occurred over a relatively short time period relative to time scale of the ice - albedo feedback, the expected rate of sea level rise should be approximately 3 m / C * 0.8 C / 560 y
= 43 cm per century.
Radiative forcing can be related through a linear relationship to the global mean
equilibrium temperature change at the surface (ΔTs): ΔTs
= λRF, where λ is the climate sensitivity parameter.
