There is a lot wrong in this post but I will only comment on the bigger picture. Don’t confuse weather with climate. Climate models are not trying to make the deterministic predictions of weather models. While both use the N-S equations on a rotating sphere plus diabatic processes, the application is different. Climate models are trying to capture the longer term trends.

Virtually all predictions have a probability function.
Weather cycles are thousands of years long. Perhaps millions. Both warming and cooling. The speck of time is a blip on that scale. Weather forecasting is often still a 50/50 guess even 24 hours in the future. Predicting 100 years is impossible. Especially with the "long range" (3 to 6 month) forecasts being wrong more than they are right. There are too many unpredictable and unknown external factors that cause a shift.
