Your assessment of the lack of motivation for parents (and others) who do not act to recalibrate the arc of our growing climate disaster is grim. I’m not a parent; and I am a septuagenarian without a lot of time left before I will be crossing to the other side. Nevertheless I engage with young people and parents in my daily activities. I often bring up the topic of our climate emergency with the younger generation and parents with toddlers and schools-age kids. No one is particularly happy to dwell on the subject. I’ve posited the notion with people that it wouldn’t be a bad idea to just imagine living in a hot world and doing some mental preparation (and occasional practice of some skill sets for living with less in a post-capitalist fossil-fuel fed society) but the answer is usually that being a “prepper” is a mindset that only steals time from living in the here-and-now. There is a lot of fatalism taking up space in people minds right now.
