Exercise 1 Calculation of climate sensitivity 1. Consider the simplest, single-layer radiative model (planetary albedo A, land surface temperature Ts). Calculate the climate sensitivity 4, associated with this black body. Do the numerical application. 2. Consider the more complex radiative model, integrating the absorptivity a of the atmosphere in the infra-red. Express the resulting radiative flux Q in terms of the data in the statement. Calculate the associated climate sensitivity Aoa- Do the numerical application for a = 0,77 et Ts = 288 K. 3. The radiative transfer models predict that by doubling the carbon dioxide concentration, the applied radiative forcing is 3.71 W.m². Deduce the temperature change associated with this forcing. 4. What climate sensitivity would be associated with the projected temperature increases by 2100 ? Conclude.
