NASA is usually a good place to start. Their articles are clearly written for laymen, they're proven to do good science, and you can't say that NASA is overly political. Basically, the consensus I can find is this: 1) The earth is warming, and it's our fault. There is no credible debate here - CO2 causes warming, and we release a crapload of CO2. 2) We're on track for something like 4°C by the end of the century. That's the difference between an ice-age and current temps (https://xkcd.com/1379/ https://xkcd.com/1379/). So we're on track to find out what the opposite of an ice-age is by 2100. 3) What does "the opposite of an ice age" mean, besides warmer? Wetter. 4) All the models have thick error bars, though. For temperature, think of everything as being plus-or-minus something like 25%. Our current warming is well within current error bars, despite what deniers will tell you. 5) Sea level rise will happen, but of course slower than Gore and the like said - those previous predictions were using worst-case-scenario things. Remember, error bars. Also, when talking about sea-level-rise, don't think of it as "Miami swallowed by the ocean", but think about storm surges and floods creeping further and further in land. A house doesn't have to be permanently under-water to be inhospitable due to sea-level-rise - an annually-flooded-basement will do that just as well. 6) What else? That's where it gets iffy. There are millions of different theories with varying amounts of evidence supporting them - some of them quite apocalyptic. Extreme weather, shifting climates like desertification, heat waves, etc. vicious-cycle positive-feedback-loops like cloud collapse (https://techcrunch.com/2019/02/25/climate-change-kills-off-clouds-over-the-ocean-in-new-simulation/ https://techcrunch.com/2019/02/25/climate-change-kills-off-c...). The biggest threat of climate change is what happens if the Global South becomes inhospitable. There are billions of poor people who cannot survive if their countries become deserts. And if that doesn't sound like Your Problem, remember that some of those people have nukes.
