temperature

higher minimum temperatures – One particular feature of global warming has been the steady rise of minimum temperatures which, amongst other things, can result in more likelihood of pest problems in coffee plants.

reduced temperature range - Coffee is quite sensitive to changes in temperature and requires certain regularity for optimal growth. The reduction of temperature range is hypothesized to have an impact on the quality of the coffee bean itself.

higher maximum temperatures – Although maximum temperatures do not seem to be increasing as much as minimum temperatures, higher temperatures are occurring with increased frequency. This can cause severe stress to the coffee plant, making it more susceptible to attacks by pests and diseases.
