Catastrophism about climate change can also affect mental health (and polarize people).
Natural disasters also affect mental health. This isn’t to say that all Natural disasters are intensified by climate change, but there could be some indirect link between a warmer/colder world and mental health (although in the case of the game, we can’t bring about an ice-age with negative emissions, so for now, it would be about a warmer world).
So, climate change could have an indirect impact on mental health (natural disasters), or a direct one through catastrophism (perhaps this could be modelled as climate change as one of the factors increasing social media use, social media use increasing polarization, polarization impacting mental health).
Just a suggestion, it could function in a different way.
Could foster political extremism too? Through deep green (hard green/doomers/human extinction proponents, etc.) and/or ecofascist movements?
This also ties into the mean world syndrome, natural disasters seem worse in human terms, and in economic terms they could be (absolute adjusted for inflation, not relative to gdp), but better tech and predictive power has reduced deaths from natural disasters by 99.7% since the 1930s in the World, and that happened while the population quadrupled. Things seem worse, but they aren’t really, we’re safer now as a whole than we ever were at anytime in human history.
Not just that, but the number natural disasters have fallen as well by 10-20%, they have increased in intensity, but that is manageable as the data shows. Their impact relative to gdp has fallen as well.
