The paper I cite is for sea level rise. IPCC models from 1990 and 2011 have made forecasts on sea level rise. When we compare those to what actually happened up to 2025, we see that we are slightly worse right now than their highest sea level prediction that was made.
We're worse than their worst case scenario, so their models were significantly too optimistic.
In the same paper, they also note that for temperature, the models have been accurate.
