Those factors are being upended by climate change.
How, exactly?
It’s my understanding that coffee does best in warm climates. Shouldn’t global warming, at the very least, change where we grow coffee as opposed to just removing the areas we can grow it in?
Others have given the detailed answer, but the really simple one is this; “How many jungle plants grow well in deserts?” If it was simply a matter of “hot = good”, surely the answer would be “all of them.”
There are specific conditions that every plant requires to grow well. Some plants are more tolerant of disruption to those conditions, some less so. Climate change affects all of those conditions. Increased global temperatures can make some places hotter, some places colder, some places wetter, some places dryer, and have all sorts of other knock on effects too.
It’s not quite as simple as that and there are other growing conditions that are required. If we take Arabica, it requires a very small window temperature window, sunlight but not so much it scorches the plant, a particular pH of soil, and consistent rainfall.
Climate change brings unpredictability to growing conditions so even if you had to move where you grow it, it won’t necessarily mean it’ll grow well. Plus different locations can bring on new diseases for the (coffee has its fair share of diseases to combat with) and so new varitals would need to be selected which is no simple task.
As the article points out, coffee is notorious for being fussy when growing it.

Short answer: more atmospheric heat = more energetic weather = more extremes and variation.
Many crops don’t just need an average temperature, they need protection from extremes and the climate they evolved for. Buckle up.
