I guess I would look more into the direction of trying to make the existential threat tangible. Show the Dutch that the rising water level is gonna feck em up with well edited demonstration videos of their water defenses collapsing.
My personal feelings on this have been very influenced by seeing animal rights propaganda and seeing how others react to it.
There are common features in both causes. The direct influence of animal ag on emissions. Pretty widespread agreement on the science (good consensus on animal cognition and environmental impacts of growing animals, total consensus on climate change).
But two common features are very important. One is that a lot of influential organisations (like oil companies and agribusiness) profit off the current model, and use this influence to do fake research and spread false propaganda. The most important common feature is that the movement for animal rights and climate change activism are both protests for self-denial, less pleasure, less convenience, etc.
About the kind of thing you are showing:
The biggest genre of climate change video in the 00s, including An Inconvenient Truth itself, was exactly about rising sea levels, coastal flooding, etc. It was hegemonic for a decade - a decade of passive acceptance of the science and a shrug in terms of politics and economics. As years go by, the severity of the steps needed become more drastic, the protests become more varied and more frenzied, and are still met by a shrug and now also a frown.
We need top-down action which will necessitate negative lifestyle changes. Free/democratic/liberal governments do not have the will and capacity for that kind of top-down action when it is opposed by large sections of capital, and their people are not going to tolerate negative lifestyle changes.
The first government, for example, that proposed reducing meat consumption as part of their climate goals, was in very unfree China - and as far as I know, even they haven't dared follow up these recommendations with any actions at all. Because disincentivising meat would make the Shanghai lockdown look like the most popular govt decision in history.
I'm going to write a longer thing about the insane discourse surrounding Chinese EVs and solar panels, but it's clear that a long-term problem like this is just not important enough for capital, government, or people. So the few people who can see what is coming very clearly, and who have the misfortune of not being cynical cowardly husks (which I am), go insane and protest in insane ways.
