The role of statistical analysis in the process of establishing and
utilizing climate and other environmental
models is discussed. The role of empirical evidence is made explicit by having not only dynamical equations but observational equations as well. In ``quasi-realistic models'', statistical thinking is encoded in the parameterizations, and is required for extracting experimental evidence and for validation. Data assimilation techniques are used to systematically combine observational evidence and quasi-realistic models. While quasi-realistic models serve as complex substitute reality, is dynamical knowledge represented trough simplified models. These ``cognitive'' idealized models have to be fitted to observational data when adapted to real situations.
