A survey by the Royal Botanical Gardens in London has found that climate change is having an impact on the coffee people depend on. Coffee trees will gradually die out with climate change, such as Arabica, the most popular coffee variety, which is likely to disappear by 2080. According to a survey by British scientists, it is only wild coffee trees that are more likely to die out. Coffee trees planted by people are actually "close relatives" of wild coffee trees. According to research published in PLOS ONE, the public science journal, Davis combines data from field trips to Africa with computer simulations of different climates to understand how climate change will affect a variety of wild coffee plants. His investigation focuses more on some local wild coffee trees in Ethiopia, which are genetically closer to Arabica coffee trees.
