Global warming threatens top coffee species

First beer, now coffee?

About 60 percent of the world’s wild coffee species are at high risk of extinction, a new study suggests.

According to the new research, coffee species are facing a wide range of threats, from increasing numbers of droughts to faster spreading of fungal pathogens as global temperatures rise.

The results showed that 75 wild coffee species are considered threatened with extinction; which is one of the highest recorded threat rates for a plant species.

In fact, researchers report that there are several species that haven’t been seen in the wild, or in cultivation, for over 100 years.

Threatened species include the popular commercial coffees arabica and robusta.

“As temperatures increase and rainfall decreases – the suitable area for growing … diminishes,” study lead author Aaron Davis told Reuters. Davis, of Britain’s Royal Botanic Gardens at Kew, told CNN that “considering threats from human encroachment and deforestation, some (coffee species) could be extinct in 10 to 20 years, particularly with the added influence of climate change.”

The study was published Wednesday in the peer-reviewed journal Science Advances.
