It should be noted, however, that if anthropogenic inputs are significant, as claimed by the climate scientists whose work we are discussing, predicting the climate would require predicting all anthropogenic climate forcings—and therefore we might expect the predictions to be worse than anticipated.
They can get around this by expressing their predictions as a function of future anthropogenic emissions, thus removing this source of uncertainty.

From the papers I looked at today, a major problem appears to be measuring the forcings that go into the model.
I imagine they do—do we have a climatologist in the house?
I imagine they do too; the question is whether they claim the right to (retroactively) “massage” their predictions, which would invalidate this test.
