You're right... all predictions are based on insufficient data and do not include chaos theory. Therefore its best to ignore all predictions, period.

But don't ignore the direct observational data or the physics of greenhouse gases (GHG). Glaciers have receded at a rapid rate and further back than previous normal patterns. Arctic ice is thinning and expanding, as are the Antarctic ice sheets, due to warm water welling up from below. Ice loss in the Arctic was measured at 27% and Antarctic beyond "normal ranging patterns at 8% to 2018. Global average atmospheric temperature is 0.98 degree C above the average temperature to 1975.

Ignore the computer modelling... it is speculative based on probabilities. This doesn't add up to reality... but the real data is valid.
