Climate change might cause a global beer shortage, which could make your beer more expensive.
Extreme drought and heat are leading to smaller barley yields, which is the main ingredient in beer.
A study done at Peking University and published in scientific journal “Nature Plants” looked into how climate change could affect global barley yields. The study used different models to test possible scenarios that could result from climate change. It forecast factors like temperature, rainfall, and precipitation.
According to the results, “the majority of countries will have a decline in barley.” The study projects a decline in global barley yields between 3% and 7%.
In the worst case scenario, global beer consumption would decline by a projected 16% and beer prices would double. In the U.S. alone, these conditions would lead to a 20% reduction in consumption and a 50% price increase per bottle.
If climate change conditions aren’t as bad, the study predicts beer consumption to decrease by 4% and prices to increase by 15%.
“For perhaps many millennia, and still at present for many people, beer has been an important component of social gatherings and human celebration,” the study stated.
This study comes on the heels of a recent UN report urging for global restructuring of energy industries.
