How Climate Change Could Eventually End Coffee
Researchers are desperately trying to keep up with new threats to the plant caused by global warming
Millions around the world wake up and brew a cup of coffee before they start their day. But for many involved in the industry, a caffeine buzz isn’t keeping them up at night—instead, what’s causing insomnia is the increasing difficulty that climate change causes coffee farmers.
Coffee is one of the world’s most traded commodities. Each year, more than $15 billion worth of coffee is exported from 52 countries—many of which are still developing and rely on the crop to buoy their economies. The industry employs some 26 million people worldwide.
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.
