Eight foods we might lose because of climate change
Never, firstly because the best coffee grows at the high altitude anyway, which contributes significantly to a coffee’s taste.
Mountainous regions are colder and the temperature increase is unlikely there.
Secondly, the worst case scenario, there are other sources of caffeine including synthetic caffeine. 
Mountainous regions are colder and the temperature increase is unlikely there.On what do you base this conclusion. Global climate change is not limited to lower latitudes. Warming trends are as likely to affect higher altitudes as they are to affect higher latitudes as far as I am aware. The loss of snow on Mt Kilimanjaro and the loss of glacier ice are good examples of this process.
I remember reading a research published by iopscience http://iopscience.iop.org/ which claims that the temperature at higher altitudes would increase during winter and spring (even greater compared to low attitudes) and this explains the loss of glacier ice etc. Apparently it is caused by increases in longwave radiation. The research hasn’t found the correlation between low and high altitudes during summer times. My understanding is that the climate in the mountainous regions will be softer, with warmer winters, springs and autumns. Summer temperatures are still going to be cooler… Perhaps I am overly optimistic here. It would be good if someone with Environmental Sciences background could comment on this.
