We probably won't die out by then, but civilization will have likely collapsed or face significant peril in most of the industrialized world.
There's too much focus on global climate change. The big picture problem is ecological overshoot, of which climate change is one of many devastating consequences. Overuse of natural resources like water, forests, marine life, etc is another.
We probably would have been fine if we had somehow decided back in the 1950s that economic growth wasn't all that necessary and kept a lid on the human population at or around 2 billion or so. But we now have 8 billion people who use a scorecard measured in property/land ownership and increases in output and consumption, and probably 85% of the population desires a standard much higher than what they already have. The other 15% wants to maintain and even augment their status as well. It's unsustainable.
Our current economic situation is actually not entirely a bad analog for a much more dire situation that is coming. Consider the fact that now, in 2023, we have an inflation problem, and a debt problem. Inflation is sticky and difficult to bring down - why? Because there are way, way, wayyyy too many dollars chasing too few goods. We thought fixing the supply chains would do the trick, but as it turns out, we overproduced currency and we are now overconsuming. The only way this can be fixed is a recession - a kind of mini version of a collapse, if you will. Well that's what will happen in the future, but instead of running out of fiat currency, we're going to run out of things that a central bank can't regenerate: water, food, habitat.
The scary part is that people will gradually come to this realization. And when they do realize the increased scarcity, the likely result will be warfare on a very large scale.
