Underwater volcanism notwithstanding, let's get back to the accuracy of modeling.

Therefore, if there is some important - but as yet poorly understood - process that they are missing, they will all tend to make the same error. Past evidence for this is the tendency for climate models to drift away from a realistic climate over time. This suggests that it takes a higher level of understanding to capture the intricate processes that stabilize the climate system.

December, 2007 RESEARCH UPDATE: We have received back from peer review our article showing how natural climate variability has probably been misinterpreted, at least partially, by researchers who claim to see evidence of positive feedback (which would make global warming worse) in the climate system. Our article was carefully reviewed by two of the world's leading climate model experts who both agreed that we have raised a legitimate issue that has been previously ignored. Those reviewers even developed their own simple climate models to demonstrate the effect to themselves. It is still not known how much of an effect this is, but accounting for it would logically reduce estimates of how much global warming can be blamed on mankind. ...
