As if enough of you didn’t already consider global warming to be a serious threat, it turns out climate change will probably have a negative effect on the production of malting barley, a key ingredient of beer
providing the tasty hops that make it drinkable, in regions where it’s primarily grown like Australia and New Zealand.
Cry about it!
ABC News: Global Warming = Expensive Beer
[EDIT] Comments drop some agrarian knowledge: production of hops used to flavor beer is also threatened by climate change, possibly meaning more money for crappier beer. How’s that for bittering hops? Harrrr.
