The way things seem to be heading, I'm afraid we're going to have much bigger problems by 2059 to worry about.
Pliocene and Eocene provide best analogs for near-future climates https://www.pnas.org/content/115/52/13288/tab-figures-data
... there's also the science.
At that time, the Pliocene (+5deg) areas are quite small and sparse. If there are thriving human populations left, they're going to be in those pockets. They're going to be doing agriculture in domes - greenhouses, because evaporation will be a major impediment to growing food in the open air.
Germination is highly sensitive to temperature - we need to focus genetics research on high-temperature stress-resistant crops, not designer babies for the well-to-do. Primate populations weren't dependent on rice, but it provides 1/5th of the calories consumed by humans.

Have you ever been in West Texas during summer?
I corrected you because one of the biggest weapons in the arsenal of climate change deniers is taking an incorrect but tangential argument and tearing it to shreds, and then pretending they tore the entirety of climate science to shreds. Bad arguments on our side are a massive liability.
