FWIW and IME: not by trying to reduce the uncertainty through study. I spent a few years studying climate models. I have lots of background in mathematical modeling and numerics, but not climate per se, so this was a big undertaking but possible. I have to admit that -- although I can now read and understand papers better -- it hasn't been particularly illuminating. The global climate is changing. The long-term impact of these changes is difficult to know, particularly because there are many plausible bifurcation points. Beyond some basics, the TL;DR is "we just don't know exactly what will or won't happen, or when, but it's probably not going to be good for most people on the planet and things are probably going to start getting bad within 1-2 hundred years". In my mind it's really just a case where being a conservative is the best approach.
