We don't have what you would accept as proof, and therefore it "most likely doesn't even need fixing"?
The vast majority of climate scientists are in agreement. That's as close to proof as science gets. If you wait until 100% of scientists agree before you take action, you never will.
And even if 100% of scientists agree, in will come people saying "science has been wrong before, so they're probably wrong now!"
