It is considered that climate change could deprive humanity of many food products. Scientists already there are fears that in the future the Earth will become unsuitable for the growth of some plants, and people become unavailable chocolate, wine and even Tabasco sauce. A new study published in the journal Nature Plants Monday, suggests that by the year 2099, mankind can even lose the most ancient beverage — beer.
The results of the study showed that due to extreme hot conditions expected by the year 2099, the yields of barley will be reduced from 3% to 17% worldwide. Depending on the region the price of beer can be increased from 52 to 300%. It turns out that today’s beer costs $ 4 in the future will cost from 6 to 24 dollars.
On the basis of this work was climate data for 1981-2010 years and four climate models. The calculations showed that the greatest damage to the barley crop will be applied in Russia, Ireland and Brazil — these countries are experiencing the most dramatic warming. At the same time, Belgium, and Japan can produce more beer and the drink will become a luxury for many people.
According to scientists, in most regions, the yield of barley will remain at a satisfactory level. However, scientists did not pay attention to other factors that can destroy the harvest. These include pests and natural disasters like flooding.
The researchers recalled that due to lack of beer nobody dies. Moreover, a smaller amount of its use can have a positive impact on the health of the population.
It is not far from the only scientific study on the topic of beer. For example, in 2013, the brewers have cloned a beerfound on a ship in 1840. In 2018 the brewers from Australia, has created a beer with a reduced amount of gases specially for astronauts.
