Maybe the answer is for someone to work on boosting natural caffeine levels in yaupon holly tea.
It grows wild all over the SE US and can withstand multi-year drought or regular floods though it does best in a situation where it gets regular rainfall. You may have some in your own yard used as a hedge plant. I have several large trees on my place. It spreads underground by suckers and will take over an area if you do nothing to contain it. It is very strong once it forms a thicket. I have driven across a yaupon thicket in a seismic buggy and been in a situation where none of the tires were touching the ground as I drove because I was crossing a thick tangle of yaupon that supported the vehicle.
Caffeine levels are lower than coffee beans (40-60 mg versus >150 mg I think). Yaupon does also have theobromines, vasodilators, that are supposed to help it prevent the caffeine crash.
I have some leaves dried and drink it make a tea occasionally when I want a boost but not a cup of coffee level boost. It tastes great and is easy to prepare at home.
There are other sources of information about yaupon holly. It is proposed that the British naturalist who discovered Native Americans using it in their own ceremonies and drinking it casually decided to name it ilex vomitoria not because it was dangerous or poisonous to consume but because since it grew wild in the colonies, it could be a serious competitor to English tea so he used the name to make it less attractive.
Caffeine production is likely difficult in the face of a drier climate. Caffeine is present in the plant as a pesticide. Insects are a much bigger problem in wet climates over dry.
Having grown up in a wet climate (Chicago) but now living in a dry one (Utah) I can say that finding a droubt tolerant species which concerns itself with pesticide production may be difficult. The same water which coffee relies on is the same stuff pests rely on to reproduce. My mother was from Utah, and she always lamented at the small size of her flowers growing up in Chicago. They are much larger in Utah because they can get big without insects eating them.
(I say all this as a point of interest, but I don't drink coffee myself.)
Liberica, which is already popularized in Malaysia, is another type of coffee that’s resistant to heat and droughts.
I’m introducing some plants to a rural community in Panama that had its Robusta crops ruined by the harsh summers we’ve experienced over the past couple of years.
Caffeine mgs for various brewed extracts can be lower than a cup of coffee. Even decaf still contains <.002mg, remain static over the designated beverage half-life. For third-wave, light roast blooms, containing more acid, the caffeine content is punctuated.
Other coffee beans is intriguing. Often it's very obvious as to why Arabica won our hearts, though! A while back I tried a coffee bean called Racemosa. The beans are like tiny little pellets, and when you drink it your eyes will widen and go.. "WOW. HGRRRGH. EW. HMM.. INTERESTING. OK, NOT COFFEE AS WE KNOW IT."
What puzzles me about the reported birth of coffee is that I wouldn't expect that just eating the cherries would give you that much of a caffeine kick to be noticeable. Yes, there's a little bit of caffeine in them, but far more in the "beans" (seeds).
Coffee crop failures have been around as long as there have been coffee crops, this idea that current coffee could go extinct is silly. Ideal locations for growing coffee can change and evolve over time, but an extinction event? C’mon. If that were to happen, there would be any people left to care.
Literally everything is blamed on climate change these days. Too much snow? Climate change. Too little snow? Also climate change.
A few years ago I was climbing Mont Blanc and the rockfall due to a warmer winter was blamed on climate change, then a few years later: near-record snow. It’s taking on religious overtones: rather than things happening because it’s God’s will — now it’s “climate.”
I am not denying that the climate changes, I am only calling out that literally every mishap in the natural world is being blamed on it. There is a lot of money in that business.
It is amazing how inefficient water use seems to be in plants.
Dry biomass growth is ~1kg/m^2/year, wet maybe 4-5x that. But they see ~1m of rainfall, so 1000kg/m^2/year of water. The roots fail to take up some, but the rest seems to be ~99% lost due to transpiration (some of which is necessary for heat stress and/or pump up nutrients).

James Hoffman did an interesting episode on this bean a few years ago, very cool the work being done.

Maybe, but Taiwan and Australia have some of the best coffee these days.

Maybe after C4 rice we can get C4/CAM coffee?
