If only more efficient models with a lower cost can be created, only then a significant improvement can be seen in this field worldwide.

The models are numerical models that use equations to describe the factors involved. For example x (whatever it is) is a function of y (whatever that is). There should be, but of course there is not, an equation to describe EVERY influence on the climate. All equations, suitably weighted, must be included in the model. Even simple models, such as earth resistivity in which there are only two variables, fail very quickly with increasing layer numbers because of the principle known as equivalence. Modelling the climate is impossible simply because of the number of factors influencing the climate, the sheer impossibility of expressing some of these mathematically, the arbitrary weighting of these factors and, even if all these things are known the principle of equivalence would make nonsense of it.

Thanks!
