The Race to Save Coffee / “If nothing is done, the amount of suitable land to grow coffee will decline by half. You do the math.”

Centro­americano, a new variety of coffee plant, hasn’t sparked the buzz of, say, Starbucks’s latest novelty latte. But it may be the coolest thing in brewing: a tree that can withstand the effects of climate change. Climate change could spell disaster for coffee, a crop that requires specific temperatures to flourish and that is highly sensitive to a range of pests. So scientists are racing to develop more tenacious strains of one of the world’s most beloved beverages. In addition to Centroamericano, seven other new hybrid varieties are gradually trickling onto the market. And this summer, World Coffee Research ­— an industry-funded nonprofit group — kicked off field tests of 46 new varieties that it says will change coffee-growing as the world knows it.
