I don't know much about science, and even less about climate science. So as a practical matter, I like to side with the majority of scientists until they change their collective minds. They might be wrong, but their guess is probably better than mine.
That said, it is mind-boggling to me that the scientific community can't make a case for climate science that sounds convincing, even to some of the people on their side, such as me. In other words, I think scientists are right (because I play the odds), but I am puzzled by why they can't put together a convincing argument, whereas the skeptics can, and easily do. Shouldn't it be the other way around?
As a public service, and to save the planet, obviously, I will tell you what it would take to convince skeptics that climate science is a problem that we must fix. Please avoid the following persuasion mistakes.
1. Stop telling me the "models" (plural) are good. If you told me one specific model was good, that might sound convincing. But if climate scientists have multiple models, and they all point in the same general direction, something sounds fishy. If climate science is relatively "settled," wouldn't we all use the same models and assumptions?
And why can't science tell me which one of the different models is the good one, so we can ignore the less-good ones? What's up with that? If you can't tell me which model is better than the others, why would I believe anything about them?
2. Stop telling me the climate models are excellent at hindcasting, meaning they work when you look at history. That is also true of financial models, and we know financial models can NOT predict the future. We also know that investment advisors like to show you their pure-luck past performance to scam you into thinking they can do it in the future. To put it bluntly, climate science is using the most well-known scam method (predicting the past) to gain credibility. That doesn't mean climate models are scams. It only means scientists picked the least credible way to claim credibility. Were there no options for presenting their case in a credible way?
Just to be clear, hindcasting is a necessary check-off for knowing your models are rational and worthy of testing in the future. But it tells you nothing of their ability to predict the future. If scientists were honest about that point, they would be more credible.
3. Tell me what percentage of warming is caused by humans versus natural causes. If humans are 10% of the cause, I am not so worried. If we are 90%, you have my attention. And if you leave out the percentage caused by humans, I have to assume the omission is intentional. And why would you leave out the most important number if you were being straight with people? Sounds fishy.
