people are aware of it in the sense that it’s a thing that vaguely exists on the horizon
if society doesn’t want to be melted by climate change, that demonstrably isn’t going to be enough to stop it
I’m not so sure. That was probably true before the past decade of record breaking heat waves, intensifying storms, etc.
Now it’s a variety of other problems, from not giving a fuck and hoping god raptures them before then, to having other priorities like the economy and thinking technical solutions will fix it, to not believing it’s human-caused, etc. It’s political hurdles now, convincing people of the importance of helpful measures, as opposed to simply trying to remind them of the problem.
