Bier wird teurer dank Klimawandel
Wissenschaftler an der Uni Peking haben die Preise für Hopfen anhand fünf verschiedener Klimawandel-Szenarien ausgerechnet und selbst im moderatesten Modell (in dieser Studie mit einem Temperaturanstieg von rund 2,5°C) steigt der Preis um bis zu 90 Cent pro Flasche, beim extremsten Modell mit +5°C um 2-5 Dollar pro halben Liter, bei einem Rückgang des Bierkonsum um Millionenbillionen Liter und hundertdrölf Kästen.

Paper: Decreases in global beer supply due to extreme drought and heat
A new study from Nature Plants might have identified the one climate-related issue that can unite people from myriad political backgrounds—beer. Led by Wei Xie, an agricultural scientist at Peking University, the paper finds that regions that grow barley, the primary crop used to brew beer, are projected to experience severe droughts and heat waves due to anthropogenic climate change.
According to five climate models that used different projected temperature increases for the coming century, extreme weather events could reduce barley yields by 3 to 17 percent. Barley harvests are mostly sold as livestock fodder, so beer availability could be further hindered by the likely prioritization of grain yields to feed cattle and other farm animals, rather than for brewing beer.
The net result will be a decline in affordable access to beer, which is the most commonly imbibed alcoholic beverage in the world. Within a few decades, this luxury may be out of reach for hundreds of millions of people, including those in affluent nations where breweries are a major industry. Price spikes are estimated to range from $4 to over $20 for a standard six-pack in nations like the US, Ireland, Denmark, and Poland.
