All of weather/climate modeling is non-determistic i.e. could produce different results for identical inputs. Weather is an open system (cause -> effect -> cause) vs. some other phenomena in physics (just cause -> effect) Doesn't make them "unscientific" necessarily - could be useful in many situations e.g. short term weather forecasts.

But when it comes to long term climate modeling, all bets are off. There is very little data to use fo such ambitious long term models, and you can make whatever assumptions you want to produce any result that fits your narrative. Politicians and their climate "scientists" do this routinely to control you.

And the people on the Left that lecture you about how they support "science" and you are an idiot - they don't know the fucking difference. They just want to feel superior to you.
