This year's coffee prices area already at a 12-year high due to low crop yields in South America, but it looks like prices could tighten again in the future if a particular beetle continues to bask in warming weather. Arabica coffee, a climate-sensitive plant, is grown in Ethiopia and Latin America. However, Ethiopia and other regions have seen a slow but steady rise in average temperatures, more variable rain fall, and what could be most devastating, the spread of the coffee berry borer beetle which enjoys just such a temperature rise to be able to move into new locations. Non-existent in the late 1960s, the beetle is now widespread, and could become a major problem in future coffee crops.
