I think there's enormous reason for concern, but... I also think there's a not-so-fine line between saying (A) that we will go through some major hardship and decreased quality of life as we attempt to mitigate and adapt, versus (B) civilization is finished, there's nothing left but despair and destruction, kids have no viable future on this planet, etc. The latter strikes me as a mass projection of millenarian eschatological thinking onto what is admittedly a troubling set of data. I suppose that policy makers find it useful, therefore, to stoke a certain amount of sky-is-falling panic, particularly among teenagers who are more inclined to be attracted to and scared of doomsday scenarios. But by the same mechanism (ie supplanting rational discourse with doomsday panic), a counter-movement scores easy points saying "look, nothing's happening." The same basic flaw on public messaging pertains to vaccines and masks. What seems to have happened is that those in charge of public messaging have concluded that the majority don't know enough or care enough about science, and so they need to tap into raw fear and emotional appeals just like the science deniers do. What this does, unfortunately, is cheapen the conversation to the point where we're measuring the stress levels of teenagers as if that were a useful metric of how severe climate change actually is or will be. Their stress levels, just like the stress levels of anti-vaxers, aren't based on rational thought; they're generated by fear-peddling from one messaging system or the other. As both these systems try to out-alarm each other, they tend to drift further toward worst-case scenarios and their exponents move closer to shouting for revolution (e.g. Jan 6th), if only to serve as post-justification for the hysteria they engender to serve their goals. Climate scientists shouldn't stoop to the level of deniers. It's too short a game to keep people in panic at all times. If we've learned anything from the failure of messaging during covid, it's that trying to sustain an endless freak-out
doesn't work, and it's ultimately counterproductive, because daily life causes drift away from any singular narrative, and groups of people then grow stronger counter-narratives even more dangerous than those they had before.
I feel sorry for kids whose lives are made to feel meaningless and short-changed by this information warfare on both sides. Yes climate change is real and dangerous and yes the world needs to be proactive, and yes quality of life will decline, more in some places than others, and mostly falling on the global poor. Yes children should be educated about it and yes adults need to get ahead of it, including changing systems and practices that there is deep resistance to changing. But panicking the hell out of 14 year olds - or in this case, 50-somethings, that civilization is imminently coming to an end is going to have the terrible consequence of hastening or creating an end through instilling abject despair, rather than cultivating the means and the will to make the necessary changes.
