Those would put strict constraints on any computational model, one could literally test
model output against them.
However, when comparing
model outputs against Hurst climate persistence, I find that the catastrophic majority anthropogenic global warming hypothesis to be formally «Not Proven» per Bray (2005), and Johnson (2013).
This obviously has implications for some papers on recent temperature trends, although the better papers which compare coverage - masked
model outputs against HadCRUT4 are largely unaffected.

against the company and is letting a small number of volunteers join the effort to ramp up
output of the crucial
Model 3 line.
Bensmaia and his team validated the
output of the
model against data from a wide variety of experiments conducted by other research teams, and show that it matches their
output with millisecond precision.
Competing
against models like the Honda CR - V and Ford Escape comes as quite the task when Subaru doesn't do anything to increase power
output and only offers up minor changes to the exterior.
Why don't you suggest a test, and we'll put your statistical
model up
against the GCM
output and we'll see who has the best match
against the 20th C data.
The results are shown in the figure below, showing the Cowtan and Way data (in red)
against model output (they don't differ qualitatively for the other temperature data sets):
To this end, they compare the
output of the
models against observations for present climate.
Part IV: Beautiful Evidence) discovered a fragmented fingerprint of solar activity in HadCM3 runs forced with amplified solar
models and regression of the
output against the instrumented temperature record.
Despite this utter lack of historical data to verify
against the
output of the
models was useful in informing decisions.
Models are often tuned by running them backwards
against several decades of observation, this is much too short a period to correlate
outputs with observation when the controlling natural quasi-periodicities of most interest are in the centennial and especially in the key millennial range.

They warn
against interpreting the spread in
model output as the confidence interval for future projections.
There are
models that give large CO2 effects,
models that give moderate CO2 effects, and
models that give large CO2 effects as
outputs; but there are no
models that have made confirmed accurate predictions
against out of sample data.
I would be interested to hear the scientific justification for building a
model to produce time series
output and then not checking that
against empirical data of the same type one already has.
Where a plot of temperture
against those of various
model outputs shows temps plodding along while the majority of the
models race upwards?
Using existing
output data from global climate
models, the researchers plotted projections of changes in global average temperature and rainfall
against regional changes in daily extremes.
If a
model, say, a paleo reconstruction, gives you a completely bad
output in exactly the best years it had to show that it worked well
against actual thermometers (despite the calibration years), it destroys the credibility of the whole reconstruction.
Eduardo offered you to run your tests
against model output which you did not take up.
But whatever your
output or business
model, you have certain responsibilities, including protection of your property and
against liability.
