Changing Initial Temperature 1. How will changing the initial temperature affect the model? We saw that when we started with an initial temperature (remember that this is the global average temp.) of 0', the model ended up with a temperature of about -18 C. What will happen if we start with a different initial temperature? Change the initial temperature to 1, then run the model and take note of the ending temperature by placing your cursor over the curve at the right-hand side (where the time is 30 years) and then click and you should see the little box that tells you the position of your cursor. You should round this temperature to the nearest whole number
