Widespread crop failure and fisheries collapse due to extreme weather and acidic oceans could be just around the corner. I can't say that with complete certainty (and I really hope it doesn't happen), but I can't dismiss it with any confidence either.

I work in mathematical biochemistry. I'm personally confident everything you've described is around the corner.

That doesn't mean that a total collapse in our food supply is around the corner, but it does suggest a collapse in the availability of certain micronutrients to a large proportion of the population.

What that means is that the outcomes of certain nutritional deficiencies will likely become commonplace diseases societies will now how to cope with. That will of course also affect politics.

Are you able to sketch out the reasons for your confidence?
