A suggestive way of putting it, because for any software engineer worth his salt what Steve has shown beyond doubt is that climate science, not least its authoritative expressions in IPCC reports, has been atrocious in regression testing of its central general circulation and other models, taking that important term in its broadest and most important sense.
The regression model does support the climate models (CMIP3 and CMIP5 AOGCMs) pro- jections of a much warmer and drier southwestern US only if the AMO changes its 1,000 years cyclic behavior and instead continues to rise close to its 1975 — 2000 rate.
The data were then analysed together using optimisation regression modelling to identify whether climate change between 1963 and 2014 impacted the risk of conflict and displacement of people in East Africa.
All CMIP5 models with such climate sensitivities of 2.7 K or below have an ECS value estimated from regression over years 21 - 150 of their abrupt4xCO2 simulation data of 3 K or below.
On the contrary, the authors stated that to show the robustness of the main conclusion of the paper — a relatively small equilibrium climate sensitivity — they deliberately adopted the regression model that gave the highest climate sensitivity.
One of the parameters is high stand or low stand conditions based on sea level transgression / regression curves which is related to long term climate, but I am not aware of any oil companies that use anything remotely resembling what I understand to be a climate model with forcings, and certainly not one driven by something like CO2, solar or anyhting else, simply because you can not know the necessary parameters over the millions of years of geological time that you are interested in modelling.
While simple comparisons of observations with simulations by climate models have sometimes been used, the most commonly used approach is based on linear regression models (OLS), sometimes assuming error in the predictor (TLS or EIV).
«A strong warming and severe drought predicted on the basis of the ensemble mean of the CMIP climate models simulations is supported by our regression analysis only in a very unlikely case of the continually increasing AMO at a rate similar to its 1970 — 2010 increase» 7
For starters, climate models are not simple multiple regressions of several variables against the climate record which capitalize on chance.
One could create N time - series of AR1 do a multivariate regression and get a fit as good as the best climate models.
When zero - intercept regressions are used for estimation, the transient efficacy of Historical iRF is then 1.02, and the equilibrium efficacy is also 1.02 (1.09 with ΔQ divided by 0.86), based on an effective climate sensitivity of 2.0 °C for the model.
