Extreme weather caused by climate change can have devastating effects — and it turns out that not even beer is safe.

More frequent droughts and heat waves in the twenty-first century will reduce global production of barley, finds a study published on 15 October in Nature Plants1. In turn, it finds, this will decrease the supply of beer and drive up prices, even under best-case-scenario models of climate change.

Many studies have explored how climate change will affect the production of staple foods such as wheat and rice, and some researchers have also looked at how luxury goods such as wine could be affected. But nobody has considered how beer will fare, says Dabo Guan, a climate-change economist at the University of East Anglia in Norwich, UK.
