Sorry, this is typical denial discourse up there. "Oh but we are not perfect, we can't be sure".
The fact that there a greater margin of impredictability should make us even more wary of potential disastrous consequences.
Plus, scientists working on the question do acknowledge that there is a big room of impredicatability. Which is why they make best-case and worst case scenarii that vary wildly.
There's however a consensus on the fact that it's going to be bad. What don't know is how bad. Which is IMHO frightening enough
