In a paper published Monday in Nature Plants, researchers said the supply and production of barley, the main ingredient of beer, are expected to drop by nearly 17 per cent by 2100, causing prices to double in some areas.
He pointed to a fall in barley yields in the United Kingdom this spring as proof of climate change's effect on the crop.
"Current levels of fossil fuel consumption and Carbon dioxide pollution - business as usual - will result in this worst-case scenario, with more weather extremes negatively impacting the world's beer basket", co-author Nathan Mueller added in the release.
The apocalyptic impact of climate change has finally been revealed - the price of beer could soar to a tenner a pint (on top of all the global drought, starvation, rising seas and so on).
Only the highest quality grain - less than 20 percent - is used to make beer, with most of the rest used as feedstock.
"The world is facing many life-threatening impacts of climate change, so people having to spend a bit more to drink beer may seem trivial by comparison", said co-author Steven Davis, UCI associate professor of Earth system science, in a statement.
By volume, beer is by far the most popular alcoholic drink in the world, with almost 200 billion litres produced in 2017.
Beer prices in the wake of these disruptive weather events would, on average, double.
Under four different weather models that were created for the years from 2010 to 2099, the world's barley growers would see "yield losses [that] range from 3 percent to 17 percent depending on the severity of the conditions", the researchers say.
Wealthy beer-loving nations, such as Canada, Belgium and Denmark, would see the sharpest price rises.
Stark warnings about the potential impact of climate change have been issued for years.
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.
Beer prices could double worldwide and the US could see 20% decline in beer consumption-that's about 10 billion cans of beer. Few people would complain if global warming ruined Brussels sprouts, he added. China could also see a drop in consumption and Davis "joked" the US could see a decline in areas such as keg stands and beer pong tournaments, as six packs could rise the equivalent of an extra $20 in Ireland and other countries. Consumption in the United States could decrease by between 1.08 billion and 3.48 billion litres. Consumption in the USA could decrease by between 1.08 billion and 3.48 billion litres, they said.
