On top of rising sea levels and extreme weather, scientists have predicted that human-caused climate change will result in another dire effect: a disruption in the global beer supply.

During the most severe climate events, the results indicate that global beer consumption would decline by 16%, or 29 billion litres - roughly equal to the total annual beer consumption in the United States - and that beer prices would, on average, double.

The focus of the study was to examine how climate change would impact your quality of life.

The research showed that beer consumption worldwide could diminish by 16 percent during the most severe weather conditions; prices would double on average.

Climate change threatens the world with drought, rising sea levels, powerful storms - and a global beer "crisis", say researchers. Even in the best case scenario, the study predicts that beer prices will rise by about 15 percent. Other countries would most likely drink less beer, as their farmers are expected to export more barley to countries that would struggle to grow enough barley under hotter, drier conditions. As barley is predominantly utilized to manufacture beer, the lesser yield of the crop across various geographies would make it harder for the breweries to produce the beverage.

"Decreases in global beer supply due to extreme drought and heat", Wei Xie, Wei Xiong, Jie Pan, Tariq Ali, Qi Cui, Dabo Guan, Jing Meng, Nathaniel D Mueller, Erda Lin, and Steven J Davis.

This could lead to beer shortages, driving the prices up in countries including China, the US, Germany and Russian Federation.


China is expected to suffer the most severe shortages in this century, followed by the United States, Germany, and Russian Federation, the report said.

"We have to all work together to mitigate climate change and prevent this from happening".

To come up with this projection, the scientists looked at the impacts on barley crops and beer prices by blending climate, crop and economic models.

Many companies realize the risks of climate on barley, 17 percent of which is used to make beer.

In countries like Ireland, where the cost of a brew is already high, prices could rise 193 percent. "A sufficient beer supply may help with the stability of entertainment and communication in society", Guan said. The impact on beer prices would vary accordingly.

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.

"If you want to have the choice for not only beer but chocolate, coffee, tea, cigars - all of those crops are very much vulnerable to climate change".
