Oh, that's not a "might", it's pretty much a foregone conclusion. Not tomorrow, not in 5 years or even in the next decade. But not so long term, it's going to be hard to continue catering a modern day lifestyle to billions. [1]

Not so long term would be beyond 2050. 2100 sounds like far into the future... until you realize that kids born today have fair chance being alive at 79 or 80 to see the turn of the next century. [2]
We are not even talking about any children you might have of your own. This is literally everyone who gets born today. Nephews, nieces, cousins, kids of friends and acquaintances,... So, this isn't even an thought exercise in the abstract.
The insidious part of climate change are the delayed effects. Consider it like throwing a thick blanket over your body. It takes a bit of time before enough of your heat gets trapped to make you sweat. Most people will throw off that blanket once they get uncomfortable. When it comes to climate, throwing off the blanket on short notice isn't an option. So, while you - and many others - feel that humanity at large has the luxury of time to afford consider anything but climate change, generations to come will experience the very uncomfortable effects of a blanket they won't be able to shake off. That's just "present bias" in action.
Now, I don't worry constantly about the future. That's counter productive.
What I do worry about is how little action is taken even today to change that future. Sure, there are a tons of great ideas and technological advances. But electric cars or ships dregging micro-plastics out of the oceans aren't going to change this.
What really grinds my gears is that this was already known some 60 years ago. This was already an debated issue at the White House in the 1960's... and over the course of those 60 years the affirmative actions that needed to be taken to avert this, have been muddled in compromises, bureaucracy and lobbying. That's not even hyperbole. [2]

As time marches on, the window of opportunities to avert the worst case scenarios and projections shrink rapidly. If hard to accept policy choices keep being debated and pushed into the future, the future simply becomes a self-fulfilling prophecy.
That window of opportunities has already partly closed up. Climate change is unavoidable. And any future policy choices will shift towards mitigating the increasingly dire effects, rather then avoiding climate change wholesale.
As an individual, the single most powerful thing you could do is to vote for and support policy makers who do take this issue serious enough today.
