Climate change: taking a toll on coffee?

Writing in the journal PLoS One on Wednesday, research botanist Aaron Davis of the Royal Botanic Gardens, Kew in London and colleagues reported that climate warming could drive wild varieties of Coffea arabica to extinction by 2080.

“Our modeling shows a profoundly negative trend for the future distribution of indigenous Arabica coffee under the influence of accelerated global climate change,” the study authors wrote.

Arabica is the prized plant that produces 70% of the more than $15 billion worth of coffee sold around the world each year. Mostly it is cultivated on farms, which grow varieties descended from a small number of plants that were carried out of Ethiopia in the 1600s and 1700s, Davis told National Geographic this week
