I'm not sure that it is when we have large segments of the economy, the media environment, and the government (speaking from a US perspective) built around continued denial of the problem. Partially that's because they seem to think that status-quo keeps making them money. I would argue that much like deferred maintenance on a car or house costs more in the long run, sticking our heads in the sand about global climate issues is going to cost us all much more in the long run.
From a political/economical perspective, I think a lot of the climate denialism comes from the desire to gain and stay in power (not electrons, but being in control). Climate change denial is another brick (along with "anti-woke," "anti-CRT," "anti-DEI," "anti-science," etc) in the argument made everyday to convince normal folks that liberal democracy is a bad thing, democratic governance can't work, and that autocracy or oligarchy is what you really want. I suspect we're going to find out starting next week.
I am a scientist but not a climate scientist. I don't have kids but do have a nephew and two nieces between age 4 and 11, so my views on these issues are definitely influenced by fears about what they will face when they're older. Unfortunately, every day I'm more pessimistic that anything will be done to reduce emissions. To go back to my car metaphor above, the climate "check engine" light has been on for my entire life, and over the past decade or two there's been smoke billowing from under the hood, but we just keep the pedal to the floor.
I can't solve the problem, but I can help. I'm not going to hold myself up as some paragon of virtue, but will say that each of us can find opportunities to volunteer in our community, to educate young people (I've pretty much given up on people my age and older), and to reduce our impact on the world around us through the choices we make regarding capitalistic consumption, diet, travel, etc.
