This is nonsense, food production on a per-capita basis is increasing and population is leveling off.

Things are just starting to change now. Our food production levels are the result of previous efforts. Not future efforts dealing with future changes.
That's what we're worried about, not "the current steady state trend is currently going up, it's all fine!"
Aggregate data is much more relevant than anecdotes.
The theory that global warming is going to lead to food shortages in the relatively near future is not an out-of-the-blue flight of fancy on the part of random HN commenters; a UN panel in 2019 warned of this possibility, as did a 2020 IPCC report (pre-pandemic, no less), as did a 2016 study in the Lancet; this is just from a cursory examination of the Google results for "food shortage predictions global warming".
Extrapolation of historic data trends isn’t always a good way to predict the future either.
Food production per acre has increased by ~4x over a century, but that's the only 4x we ever got and the only 4x we'll ever be getting. We've been at diminishing returns for decades but will soon peak and experience lots of bad effects from unsustainable practices.
As the grandparent stated, "there will be casualties". Sure, I'm quite certain humanity will recover, and probably end up better off than we are now, but that doesn't mean the chain of events leading up to that that won't be hell.
