The chickens are coming home to roost...
My impression is that a lot of developments that were already going wrong for quite a long time, but could be ignored relatively easily, are now reaching a breaking point.
I think there is also a sort of "cascade failure" going on, on which some events are changing the conditions for more rvents to occur: E.g.: The general political turmoil inside the US led to the Trump election, which led to a weakened image of the US in the world, which may have emboldened other powers like Russia, which may have contributed to the outbreak of the Ukraine war, which has led to record inflation, etc etc.
Likewise, climate change has reached a level in which the consequences are beginning to be felt even by rich nations, and the predicted tensions and upheavals are starting to materialize.
Those are not the single "causes" of any of those events, but it might be one of many causal chains that connect all those world events and led to mutual escalation.
Where all of this is leading? I have no idea, but definitely to a different era. The question is what kind of era.
