Sadly, the problem is not computing power. The problem is simply that
there are too many unknowns with error bounds that are too large.
There are at least three types of error bands that swamp any
measurable effect of AGW so far. So how you tune the model will vary
the output by much more than AGW does. Uncertainty in cloud feedback
hydrology swamps even the worst AGW predictions by a factor of 4.

The current warming trend began around 1850. Human CO2 emissions could
not possibly have been significant until at least 1890.
