Øl-elskere rammes af global opvarmning - citat

Øl står til at blive offer for den globale opvarmning, og forskere advarer om, at klimaændringer truer med at skabe en global øl-krise. Det skriver The Independent tirsdag.

For virkningerne af den globale opvarmning vil ifølge forskere sandsynligvis føre til et kraftigt fald i den verdensomspændende afgrøde af byg, der er en af de fire væsentligste ingredienser i ølbrygning.

Forskerne forudser, at tørke og varmebølger kan forårsage en reduktion i bygafgrøderne på op til 17 pct. i dele af Europa, Australien, Asien og USA, der er kornsortens primære dyrkningsområder.

Ifølge en undersøgelse offentliggjort i den videnskabelige publikation Nature Plants vil de alvorlige klimaændringer føre til en fordobling af bygpriserne.

- Verden står over for mange livstruende effekter af klimaændringer, så at der skal bruges lidt mere på at købe øl, kan virke trivielle i sammenligning. Men der er helt klart en tværkulturel appel i øl, og ikke at kunne få en kølig pint ved afslutningen af en generelt varmere og varmere dag, føjer bare spor til skade, siger forsker Steven Davis fra University of California.

Ca. 17 pct. af den globale bygavl bruges til at brygge alkohol, mens størstedelen ender som foder til husdyr. Ifølge forskerholdet vil sultne dyr stå først i køen for den tilgængelige mængde byg i de kommende årtier, mens de tørstige ganer kommer i anden række.

Den britiske forsker Dabo Guan, der er professor i klimaforandringsøkonomi ved UEA School of Internationale Development, vurderer, at klimaændringer kan underminere tilgængeligheden af "luksus"-produkter som øl.

- Selv om der er blevet lagt vægt på de potentielle virkninger af klimaændringer på luksusafgrøder som vin og kaffe, er konsekvenserne for øl ikke blevet omhyggeligt evalueret. En tilstrækkelig ølforsyning kan hjælpe stabiliteten af underholdning og kommunikation i samfundet, pointerer han.

De store bygdyrkningsregioner med de nordlige store områder i USA og på de asiatiske stepper vil sandsynligvis opleve hyppigere tørke i de kommende år som følge af den globale opvarmning. Det potentielle gennemsnitlige udbyttetab spænder fra 3 pct. til 17 pct. afhængigt af graden af klimaændringerne.

Ølpriserne forventes at stige mest i velhavende øl-elskende lande som Belgien, Canada, Danmark og Polen.
