Average global barley yields during extreme events are expected to drop between 3pc and 17pc, depending on the conditions, said the study, published in the journal "Nature Plants".
If you crave a pint (or two) at the end of a hard day, brace yourself: climate change is poised to make your favourite lager, ale or IPA more scarce and pricey. He added that "there is something fundamental in the cross-cultural appreciation of beer".
A new study suggests climate change will cause a global beer shortage.
Climate change threatens the world with drought, rising sea levels, powerful storms - and a global beer "crisis", say researchers.
Beer is the most popular alcoholic drink in the world by volume consumed, said researchers at the University of East Anglia (UEA) in the UK. Less than 20 percent of the world's barley is made into beer. The price only jumps 15 percent and consumption drops four percent in less severe scenarios.
"Although the effects on beer may seem inconsequential in comparison to numerous other - some, life-threatening - impacts of climate change, there is nonetheless something fundamental in the cross-cultural appreciation of beer", the study said.
Research predicts heatwaves and droughts could cause a fall in barley yields of up to 17 percent across the leading grain-producing regions of Australia, Asia, Europe and the US.
Worldwide barley is used for all sorts of purposes, mostly feeding livestock. According to the USA scientists' economic model, the price of a six-pack of beer could go up by an extra €17 in Ireland.
The study showed that the price surge was highest in countries that drink the most beer: It predicted that a 38 per cent fall in beer supply will lead to massive hikes in its price in Belgium, Canada, Denmark and Poland.
Their prediction: During the most severe climate events, global beer consumption would decline on average by 16%, Guan said, while beer prices around the world would, on average, double.
Richard Ellis, professor from University of Reading in England, said that the study, which he was not involved in, could actually be lowballing the price increases for beer if nothing is done to curb climate change, according to The Guardian. Consumption in the US could decrease by between 1.08 billion and 3.48 billion litres, they said.
Decreasing yields would leave less barley for beer production, as its use as food and cattle feed takes precedence. Consumption in the U.S. could decrease by between 1.08 billion and 3.48 billion litres.
