> 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.

No. The paper does not show that. Figure 3 shows that recent sea level rise, accounting for measurement uncertainty, is in line with projections of any of the models (around 2mm per year). In any case, they call out explicitly that the recent data is of insufficient duration to make the comparison you’re trying to make.

Temperature data in figure one is more or less exactly in the uncertainty window of the models (not shocking, considering that they’re calibrated to reproduce recent data).
