If a model is calibrated on 20th-century climate data, what process confirms its framework by accurately reproducing known temperature anomalies from the early 1900s?

Answer

Verification

Verification confirms that the parameters tuned during calibration can accurately reproduce data that the model was not explicitly tuned against, thereby building credibility in its predictive framework.
