tipping point scenarios are very horrifying. And all the global warming deniers will probably be like “but it wasn’t because of global warming it was because this ocean current collapsed!”

You should try to understand others more, instead of building strawmen to give yourself an excuse to feel smug without challenging your ideas. Among the larger concerns that people have with the messaging on climate change is how the world’s largest polluters, China and India, are always completely ignored. It strikes people that, if it really were such a massive and immediate threat, then it would be completely irrational to ignore the massive contributions those economies are making to the problem. Canada, for example, could completely stop existing tomorrow and it wouldn’t make even the smallest dent in global emissions. On top of that, life in a winter climate such as ours requires significantly more emissions simply to sustain the basics required for living, such as heat, and yet many of the very same people talking about the dangers of climate change are also importing massive quantities of people from nations with warm climates where people can much more easily live with little to no emissions. All things considered, the arguments presented simply do not sound honest to many people.
