This is a sobering thought for those of us who rely on a caffeine fix everyday but more worrying for people who work in the industry. Coffee provides a livelihood for about 16% of Ethiopia's population. And across the globe, extreme weather events are proving a challenge to coffee growers in places such as Brazil and Vietnam. 

There is some hope. Technology is helping to protect the future of coffee such as 'breeding' the Arabica bean plants to increase its diversity and making it resistant to climatic changes. It's also possible to relocate the coffee-growing areas – although this sometimes leads to areas being deforested. Dr Aaron Davis, coffee researcher at Kew, says: “There is the potential to mitigate some of the negatives and actually increase the coffee-growing area by four and a half times compared with maintaining the status quo.” But will this come quick enough before our coffee turns bitter and we look for a cheaper alternative?
