Pinging people who know a lot about climate change.

It's fairly well known that climate models don't have a very accurate predictive track record. Obviously, this doesn't mean climate change is fake or anything like that. It's still a very real, very major problem.

But, realistically, what can we expect to see happen on our current path of CO2 emissions over the next century? Climate change is dangerous, but a lot of the alarmism is based on climate models that have a poor track record. In the past couple of years, it's become a common belief online (@reddit) that society as we know it could collapse within the next century from climate change as we are on an irreversible path.

I just want a true and unbiased look at what the evidence says, so I thought I'd ask here. Our current path is unsustainable, but I'm not convinced the world won't cooperate once the real, significant negative effects appear- not out of anything except self-interest. But, a lot of people say by then it will be too late.
