Climate change is probably the most clearly a “big fucking issue” for mankind. I’m fully aware it’s going to kill a huge portion of the population before the end of this century and that I’m probably going to be one of them. I don’t expect to retire or have any kind of life beyond MAYBE 60 because we’ll be locked in famine wars and constant civil unrest.

Can't say I haven't wandered those paths of thought, but what keeps nagging at the back of my mind is the possibility of a positive feedback loop of ecosystem collapse, cascading through all of it. From my limited understanding it's somewhat likely to happen but nobody can tell the exact likelihood or outcome. Best guess likelihood of it happening climbs exponentially between 1.5°C and 5°C of warming, which is why limiting warming to 1°C was determined as a threshold initially and subsequently raised to 1.5°C because 1°C became a pipe dream. Depending on how pessimistically you want to do your measurements we have now already reached those 1.5°C of warming.

The rise of global fascism and it’s persecution of “the other” or “enemies of the state” as seen in the USA, Israel, China, Russia, North Korea, Afghanistan, Pakistan, The Philippines, and many South American and African nations is another major issue that’s being largely ignored and/or actively progressed by an alarming number of people today. Is another thing that is being underplayed in the media and it going to ADD TO the major global instability that climate change is going to cause.

Yeah tell me about it, the far right party in Germany keeps getting new poll records, now breaking 20%. In fucking Germany! Thought I'd never see the day. And therein lies the crux. I think the move towards the right on a global scale is in large part reactionary towards the largest problem on a global scale happening right now, which is climate change. Of which we keep seeing incrementally bigger symptoms, chiefly among them in this context migration as well as economic problems related and unrelated to that. The sensory information of our society already indicates how vast this problem will be. And unless the underlying cause is fixed, this trend won't reverse itself; On the contrary, we will see democracies collapse left, right, and centre, pun intended.

OP is in their mid-40s.

Ok, this is too ad hominem for me, so I'm going to disregard that part of the argument.
