I meant, if one was able to select the input dataset ("source data",
not the source code) for the ClimatePredition.net application, THAT
could be used to answer questions such as this. The model really is
rather accurate.
Precise, yes! Accurate, how do you know?
Accurate because when the model runs for historical years, its data
corresponds to known data for those years. You could consider that
calibration, of course, but once the model runs as the climate has
actually run for the past years in the simulation, you would have to come
up with reasons why model and reality would drastically diverge at exactly
the current date.
I currently have models at years 1820, 1988 and 2000, running from earlier
data. If those models correspond to recorded history, I consider that a
calibration that results in an accurate model. The more runs, the more it
gets corrected, the more accurate it gets.
Anyway, if you want to play with data then try EdGCM

Interesting, thanks.
