It has not so much to do with prediction, nobody can predict everything. The science is following trends, using models and projections. There are real measures that show more instabilities, signs of weakening and the models explain why with confidence. From that we can anticipate, knowing the accumulated effects from trends may "lag" by 30-50 years. For anticipation, this means events will worsen over that span even if we stop emissions. That greenhouse gases in a closed vessel causes warming when light shines is settled science past 100 years. We see cooling stratosphete and warming troposphere, all in line with the models. It's kind of like discovering your house is on fire, then arguing warmth is good for cooking.
