But in recent years, keeping the world’s coffee drinkers supplied has become increasingly difficult: The spread of a deadly fungus that has been linked to global warming and rising global temperatures in the tropical countries where coffee grows has researchers scrambling to create new varieties of coffee plants that can keep pace with these new threats without reducing quality.
While coffee researchers can do little to prevent climate change, they’re hard at work to keep up as Earth braces for temperature increases of several degrees over the next several decades.
“Coffee is the canary in the coal mine for climate change,” says Ric Rhinehart, executive director of the Specialty Coffee Association of America. “If you can’t think about the long term risk for planetary impacts, think about the short term risk for your coffee. Know that a day without coffee is potentially around the corner.”
