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.
Barley, the main ingredient in beer, is extremely sensitive to temperature and drought, and because humans have really fucked up the planet, it means the temperature is increasing which will lead to substantial decreases in barley crops. Dabo Guan, a co-author of the study and a professor of climate change economics at the University of East Anglia, and a team of scientists examined scenarios resulting from climate change and then figured out the impact on global barley yields and beer prices.
During severe climate events, global beer consumption would decline by 16 percent, or almost 30 billion litres - equal to all the beer quaffed each year in the United States, Guan and an worldwide team of researchers reported in the journal Nature Plants.
By volume, beer is by far the most popular alcoholic drink in the world, with almost 200 billion litres produced in 2017.
Key brewing nations are forecast to be among the worst hit, including Belgium, the Czech Republic and Ireland.
Donald Trump acepta la realidad del cambio climático
Trump aseguró que no quiere ser él quien ponga en desventaja a Estados Unidos al momento de responder al cambio climático . No quiero perder millones y millones de trabajos ni quiero estar en desventaja (...) Pero bien podría revertirse.
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.
The next step was to estimate how these "barley supply shocks" would affect the production and price of beer in each region.
The researchers said that compared with life-threatening affects of global warming such as the floods and storms faced by millions, a beer shortage may seem relatively unimportant. "There is something fundamental in the cross-cultural appreciation of beer".
Guan also noted that beer crops aren't the only ones likely to be affected by climate change.
The top exporters of barley are Australia, France, Russia, Ukraine and Argentina, with many European countries filling out the top-20.
