I have constructed a much better model with much simpler assumptions. My model consists of a 60 year cycle of PDO/AMO that is +.23/-.23 in amplitude, a CO2 TCS of 1.2C. Very little effect from sun or aerosols. This model works without billions in investment. It models the actual fluctuations almost perfectly (way better than the billion dollar models) and it has the merit of simplicity.
Please link me the paper to your model, I sure love to see it if it is that simple and great.
