Computer modelling for weather forecasting, and indeed for climate forecasting, has reached its limits.

The general trend in the last 4,000 years is that carbon dioxide and temperature have been moving against each other.

It's not the case that carbon dioxide drives temperatures. When you leave Ice Ages, it's the other way around: The temperatures go up first, and then carbon dioxide levels go up.

The weather records of the U.S.A. are the best kept and most accessible in the world, thanks to consistent government/military taxpayer support. There are longer European data sets, but the U.S.A. data is enough to forecast major extreme events.

The key thing to understand is that solar activity causes shifts in the jet stream with consequent changes in weather patterns and triggers processes that lead to storm formation.
