Scientists say climate change could mean the end for coffee

More than half of the world's wild coffee species could be wiped out because of climate change and other factors, according to a new study that raises concerns about the future of global coffee production.

Scientists at the Royal Botanic Gardens, Kew in southwest London, carried out an International Union for Conservation of Nature Red Threatened Species assessment on 124 coffee species.

The newly published research revealed that 60 percent of all wild coffee species are threatened with extinction because of deforestation, climate change, and the spread and increasing severity of fungal pathogens and pests.
