Maybe it's really head in sand sort of thinking, "If I ignore it, hopefully it'll go away and I'll be fine.". I think if people really come into grips with it, they'd be living in despair fighting a frustrating battle (either against the physics, or against the governments/corporations who are moving too slowly, or against the other humans who don't really seem to give a crap). Then there's a segment who are thinking "Well, we're fucked, might as well enjoy our short lives.", which I'll admit I'm a part of (cast the first stone, why don't you).
I also have a growing anxiety of how bad it'll be in 5-10 years (refugee crises, humans/countries becoming more selfish and isolationist, so the rise of tribalism (and great, I don't look like a native of where I live), countries growing desperate for food/water resorting to use their military, leading to resource wars).
We need to rapidly increase spending on low-carbon infrastructure, remove permitting delays on building new power systems, and add carbon taxes. We also need to get serious about emergency solutions like solar radiation management, because it looks increasingly likely we'll need them to stave off total disaster.
There are still technical arrows in our quiver that could save us, but none of them matter if major political parties decide to prevent us from using them. So the real answer is: vote.
If it costs the average person a dollar more or requires them to drive a mile less, it won't happen. People are selfish and will gladly vote away their future for a more convenient today.
This isn't a 'party' problem - this is what the public wants.
I don't think the general public wanted offshore wind to be delayed by two years under the previous administration [1], but that's what they got. I don't think the broader public really wanted tariffs on solar panels, but that's what they got [2]. You are right that the public isn't up for major personal sacrifice, but this stuff is qualitatively different: even sensible actions that don't impose burdens on the public are being maliciously blocked.
