Doing model by model, run by run statistics against the observations might allow you to reject some models and tighten up the ensemble envelope.

None of current models have a sufficient number of runs to overcome chaotic uncertainty and therefore can not be validated against observations.

Of those runs, how many would pass conventional regression statistical comparisons against the observations is a very good question.

Individual components continue to be improved via systematic evaluation against observations and against more comprehensive models.

But, when you actually measure the predictions that climate scientists have made against observations of how the climate has already changed, you find the exact opposite: a pattern «of under - rather than over-prediction» emerges.
