"Even if you didn’t notice beer price fluctuations following those years—2014 and 2017—consumers probably will in the near future. Climate change will make extreme events like prolonged droughts and heat waves more severe and frequent, says Steven Davis, an earth systems scientist at the University of California, Irvine. That, in turn, could make beer (the vast majority of which is brewed with barley) dizzyingly expensive, according to study results Davis and his research team published Monday in Nature Plants."
