Climate change apparently poses a threat to the caffeinated beverage of choice for many Americans, as a number of wild varieties of coffee beans to go extinct before the end of the century, reported the Los Angeles Times.

Studying African habitats in Ethiopia, the Sudan, and Kenya, scientists found "a profoundly negative trend for the future distribution of indigenous Arabica coffee under the influence of accelerated global climate change."

Arabica beans comprise 70 percent of coffee sold worldwide. But the disappearance of wild varieties threatens the ability of farmers to bounce back when disease and pests affects crops.

However, researchers did find hope that more studies could locate specific genes that could withstand heat and drought, and they also found "core localities" where plants could survive climate change.
