Changes in the world climate could cause almost all indigenous Arabica plants — crucial to the commercial production of coffee — to become extinct by 2080, according to researchers at Britain’s Royal Botanic Gardens. Writing in a study published in the journal PLOS ONE earlier this week, the scientists describe a number of potential scenarios based on simulations of climate change in key areas, particularly southern Ethiopia. While the most conservative model shows a 38 percent reduction in suitable ‘bioclimatic space’ over the next 68 years, others veer close to 100 percent, and the researchers emphasize that additional factors, such as deforestation, have yet to be considered.

Arabica is not the only plant used in coffee…
