Robusta Coffee Beans May Not Be as Robust Against Climate Change as We Thought

Coffee beans generally come from one of two species: Arabica and Robusta.Less expensive and bitterer, Robusta tends to be a workhorse bean used when keeping down costs. .But both share a troubling similarity: They may be susceptible to climate change.Arabica beans have long been known to be extremely sensitive to climate change.But a new paper claims that robusta beans are in trouble too.Our results suggest that Robusta coffee is far more sensitive to temperature than previously thought...Robusta supplies 40 percent of the world's coffee, but its production potential could decline considerably, Global Change Biology.However scientists have responded that the news wasn't as bad as it could be.And even though Robusta may be more sensitive than previously thought, it's still less sensitive than Arabica
