"Increasingly, research has begun to project the impacts of climate change on world food production, focusing on staple crops such as wheat, maize, soybean, and rice", said Dabo Guan, a professor at University of East Anglia.
Results from the new study revealed potential average yield losses ranging from 3% to 17%, depending on the severity of the conditions, researchers said.
Climate change has already taken a heavy toll on barley.
It continued: "Although it may be argued that consuming less beer is not disastrous-and may even have health benefits-there is little doubt that for millions of people around the world, the climate impacts on beer consumption will add insult to injury".
"If you still want to still have a couple of pints of beer while you watch the football, then climate change [action] is the only way out".
Climate change threatens the world with drought, rising sea levels, powerful storms - and a global beer "crisis", say researchers. These countries are expected to be impacted the most due to the large quantities of beer they brew from imported barley.
"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.
Pippa Middleton gives birth to a boy
The news comes on the tail of Meghan Markle and Prince Harry's announcement that the Duchess of Sussex is pregnant . Middle child Charlotte was the lightest on his arrival, weighing 8lb 3oz when she was born in May 2015.
Only 17 per cent of the globe's barley is actually used in brewing; most is harvested as feed for livestock.
Forty-three percent of Americans said beer was their favorite type of alochol in 2016, according to Gallup, with 32 percent saying the same about wine and another 20 percent sticking by hard liquor.
"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", said co-author Nathan Mueller. The price only jumps 15 percent and consumption drops four percent in less severe scenarios. According to the United States scientists' economic model, the price of a six-pack of beer could go up by an extra €17 in Ireland.
"For beer drinkers, this (study) converts an abstract concept. into the more real future price of beer", Ellis said, according to The Guardian.
Climate change could reshape the barley and beer market, the researchers say, depicting a situation where China - which now drinks more Budweiser than the US - would scale back its beer consumption.
Britain would also get thirsty during a severe barley crunch, with consumption dropping by up to 1.3 billion litres, and the price of a pint doubling. Few people would complain if global warming ruined Brussels sprouts, he added.
