In addition, the
calculations can be performed with fewer
assumptions and less effort than fancy valuation
models like discounted cash flow analysis (DCF).
Ab initio
calculations mean that researchers start with no
assumptions in their mathematical
models, making a simulation more computationally expensive but also more accurate.
As a result, a chemical
model calculation with many
assumptions is the only approach.
More importantly, it is my understanding that weather is chaotic and that
calculations with Numerical Weather Prediction (NWP)
models / codes are consistent with that
assumption.
Thus they input erroneous data, simplistic
assumptions, personal biases, and political and financial
calculations, letting
models spew out specious scenarios and phony forecasts: garbage in, garbage out.
The S from the IPCC comes from a definition that assumes we know the future of the full behavior of the nonlinear system and can let the 2xCO2 effect run to completion (or absent that ideal value, can approximate it using
models and possibly also using various simplified
assumptions and
calculations to speed how long it takes to calculate the value).
