Use the model presented in the equations for the surface and atmospheric energy equilibrium to model the effect of an ice age. Suppose the combination of increased ice on the surface of the Earth and decreased CO2 in the atmosphere changes the parameters in the model as follows: s= 0.15,ta=0.12,a=0.23,C=2.5,S0=1367, and ta=0.53. All other parameters are unchanged. Identify the new values of Ta and Ts. Hint: One of the choices gives nearly a zero on the right hand side of the equations 36 and 3-7. Ta=243.1KandTs=278.7K Ta=302.7K and Ts=342.7K Ta=142.4K and Ts=164.7K Ta=430.2K and Ts=488.7K
