It is believed that climate change can deprive humanity of many foods. Scientists already have concerns that in the future the Earth will become unsuitable for the growth of some plants, and chocolate, wine and even Tabasco sauce will become inaccessible to humans. New research published in the journal Nature Plants Monday, suggests that by 2099, humanity may lose even the oldest beverage – beer.
The results of the study showed that due to the extremely hot conditions expected by 2099, barley yields will decrease from 3 to 17% worldwide. Depending on the region, the price of beer can rise from 52 to 300%. It turns out that today’s beer worth $ 4 in the future will cost from 6 to 24 dollars.
The work was based on the climate data for 1981-2010 and four climate models. Calculations showed that the greatest damage to the barley harvest will be inflicted in Russia, Ireland and Brazil – in these countries there is the most dramatic warming. However, the drink can become luxury, because Japan and Belgium can produce more beer.
According to scientists, in most regions, barley yields will remain at a satisfactory level. However, scientists did not pay attention to other factors that could ruin the crop. These include pests and natural disasters like floods.
The researchers recalled that due to the lack of beer, no one would die. Moreover, a smaller amount of its use can positively affect the health of the population.
This is not the only scientific research on the topic of beer. For example, in 2013, brewers cloned beer found on an 1840 vessel. In 2018, Australian brewers created beer with a reduced amount of gases specifically for astronauts.
