I think that's a big misunderstanding. Climate change is not exactly an immense existential threat to our species. It's threatening the livelihood and sustainability of life in almost all impoverished regions, and will cause the death and suffering of 100s of millions/billions of people.
The average 1-percenter who participates in this forum will probably see nothing more than a few tourist destinations changed, need to crank up the AC a bit more, less options for skiing in winter, and price of exotic fruits increasing.
The combination of climate change, loss of wildlife habitat, biogeochemical flows, ocean acidification, etc, could very well be a threat to our existence as a species, yes. Climate change is only one of them, and the injection of SO2 in the atmosphere only solves this one, with unclear and potentially negative consequences on all the other planetary boundaries.
