We used a 1d model of the earth in class to model climate change. rewrite the matlab code for the equilibrium temperature of the earth. assuming no greenhouse gas effects, what is the equilibrium temperature the earth would have if the following were the various constants in the model: sigma = 5.67e-8; epsilon = 0.612; alpha = 0.30; s = 1365; what is the equilibrium temperature in degrees celsius -- report only the number and not the units.
