If there is a consensus of CO2 being a problem it is for a reason. Yes. It is a big problem. This question in 2023 doesn't make sense. It is going to be worse for next generations, a massive problem and they will hate us for this. We humans knew about the problem for decades and we did nothing. Now it is too late. We must face the consequences.

We can try to mitigate it a bit, that's all. We cannot reverse it anymore at least with current technology. We needed new nuclear technology decades ago. Fusion is advancing super fast but not fast enough.

You are living a mass extinction event at high speed.
In other words. Yes. A big problem.
