I do actually worry about bananas, but anything with dates even as high as 2050, much less 2080, seem like either risks safely far away (unlikely, but possible) or overly optimistic timelines.
I'm not making light of the Climate threat. Rather, I'm saying all of humanity is in imminent peril of deadly famines and the resource wars that will accompany them, long before such far-off dates. Just to name only one of many nearer-term risks.
People seem to think that the big Climate risks are first-order ones like drowning due to rising seas or heat so high people can't in any way survive. But not everything we depend on is as robust as we are, so if our primary food supply dies (just for example), it won't really matter that our air conditioners still work or that a few bananas still grow somewhere. We will have killed each other in bloody uprisings long before.
It's the second- and third-order effects of climate, the domino effects of seemingly small things, that we should be tracking better. For example, if a country exporting bananas in exchange for other foods finds no one offering those other foods for trade, yes, we're short bananas, but what will those countries do that have an excess of bananas and a paucity of other needed goods. It won't take much before borders start to tighten up.
And then on top of it, we see the felon creating both tariff policy and international bad will that causes people to think about closing down trade for other reasons, hastening a problem that was maybe going to come. That won't make things better. It could just force a crisis even sooner.
But the idea that we'll be able to survive with global society intact doing what we're doing now in the world for another 50+ years until there's a banana crisis just does not pass the laugh test with me.
Excluding straight up greed & outright evil,
