As you said: "Predictive models must adequately replicate pass known data to be accepted as predictive of future behavior; otherwise, they are considered "garbage in, garbage out"!"
As was in the abstract of the paper: "By optimizing spectral features of the component sine waves, such as periodicity, amplitude and phase, the original temperature profiles were approximately simulated for the late Holocene period to 1830 CE. The ANN models were then used to generate projections of temperatures through the 20th century. The largest deviation between the ANN projections and measured temperatures for six geographically distinct regions was approximately 0.2 °C, and from this an Equilibrium Climate Sensitivity (ECS) of approximately 0.6 °C was estimated."
Ergo... garbage in, garbage out.
