Sorry still models and simulation. Computers give you back what you tell it to with your inputs. If your inputs are inaccurate then the data produced are also not accurate. In one sentence you say parameterizing convection is uncertain, then you parameterize it later in the paragraph. Also AGW is not proven by any stretch. Maybe it is to you but not everyone. Explains nothing regarding rainfall except that you changed some parameters and made it higher. It does look and sound very professional though.
