I'm no climate change denier but last I checked no scientific bodies we're predicting that the human race would go extinct. Stating that seems kinda ironic given you seem to be attempting to take the high-road scientifically.
Ultimately, each person is in their own world, alone.
And here we are.
The issues have changed a bit and a number of national boundaries aren't really reflective of the diversity of cultures within. Plus we now have truly global issues like Internet access, supply chains, and global warming. But perhaps this is indicative that we're in for a major reshuffling, and that existing national boundaries are going to collapse. We already have a political framework (federalism) for getting independent states to agree on matters that impact all of them while still being able to exercise their own discretion on local matters.
"If radiative forcing were to be stabilised in 2100 at B1 or A1B levels[14] a further increase in global average temperature of about 0.5°C would still be expected, mostly by 2200. {10.7}"

While extreme weather events are often claimed to be caused by global warming, none have been substantiated - as yet. When and if, then you have a point.
If there's a GC model shown to retrospectively predict global weather as observed we should pay attention. To date they do not do this. Factoring in cloud cover is a major difficulty.
Given that many more people die from cold than from heat, a profound moral problem arises with the impact of taxes on energy use. Politicians supporting limitations on availability of energy, must be clear that they believe that lots of poor people dying in misery is a price worth paying. Perhaps it is; perhaps it isn't. We should understand clearly that extinction-rebellion-minded people evidently believe it is.
Well there's your problem - comment sections on many "mainstream" sites are a dumpster fire. There was even a recent article (one every month or so) about how moderation across the internet sucks: https://news.ycombinator.com/item?id=21143526
