Not if increased water evaporation leads to increased cloud cover leads to increased rainfall. We don’t know what will happen, it’s simply too complex to model accurately.
I think the central problem is that the way they divide the atmosphere / oceans into 100km square grids is too large for local weather, but if they shrink the grids it takes way too long to run the simulations, so they are in a bind. I am of the opinion it's better not to risk increasing the amount of CO2 because we don't know what will happen. But I wouldn't consider any of our models even low-confidence. It is impossible to solve given how chaotic nature is, the number of variables, and how slow our super computers currently are.
