Im a weather watcher because my company relies on the weather. I do concrete in spring through fall and snow removal in the winter. There are two weather models that are used for US forecasts. One comes from NOAA and is usually called the North American model. The other comes from Europe and is called the European model. The two rarely agree even on short range (10 day) forecasts. The further out in time and the more they diverge.

So I have little faith (as in zero) that by modeling they can predict future climate. Garbage in, garbage out. Our understanding of past climate is imperfect at best. It is the pinnacle of arrogance to believe that an incomplete data set can be accurately modeled to predict future climate.

But this isnt even the real problem. The real problem is that government seeks certain outcomes and through grant money (basically scientific bribery) they get exactly what they want whether the data is correct or not.

(BTW the European model is usually better for winter forecasts while the NOAAs just sucks.)
