The Climate Criers are wetting their pants about Barley and Beer now.
Note this is from 2009. The point being the current “news” of barley and beer is a recycle of one they ran 9 years ago.
Colleges have always been a primary point of rally for green initiatives. Now, a threat to malting barley has created a new call for support as the price and availability of beer is being threatened by climate change according to a study conducted and released in 2008.
The potential for the alcohol industry to be effected by climate change has been a concern for some time, but it is hitting a feverish pitch and garnering support and calls to action from campuses across the country. In Lawrence, Kansas, Greenpeace volunteers held a recruitment event called “Save the Ales” earlier this week to tackle how global warming effects college drinking.
“It’s not really about the beer,” John Gawin, Greenpeace intern, said. “It just shows you how climate change can effect even small things.”
Here’s a link to Nature for 2018 doing that recycling.
Decreases in global beer supply due to extreme drought and heat

Beer is the most popular alcoholic beverage in the world by volume consumed, and yields of its main ingredient, barley, decline sharply in periods of extreme drought and heat. Although the frequency and severity of drought and heat extremes increase substantially in range of future climate scenarios by five Earth System Models, the vulnerability of beer supply to such extremes has never been assessed. We couple a process-based crop model (decision support system for agrotechnology transfer) and a global economic model (Global Trade Analysis Project model) to evaluate the effects of concurrent drought and heat extremes projected under a range of future climate scenarios. We find that these extreme events may cause substantial decreases in barley yields worldwide. Average yield losses range from 3% to 17% depending on the severity of the conditions. Decreases in the global supply of barley lead to proportionally larger decreases in barley used to make beer and ultimately result in dramatic regional decreases in beer consumption (for example, −32% in Argentina) and increases in beer prices (for example, +193% in Ireland). Although not the most concerning impact of future climate change, climate-related weather extremes may threaten the availability and economic accessibility of beer.
So I guess we’ll all just have to give up and swap to Bourbon made from corn that grows in hot places like Iowa… After all, Barley couldn’t possibly grow in places that get as hot as Arizona, our future and destiny temperature (per the wet pants brigade) right?
Arizona Durum wheat production down, barley up this year
2017 Arizona Durum wheat yields average 97 bushels/acre; barley yield at 125 bushels/acre
Looking at barley, NASS estimates 2017 Arizona production at 2.38 million bushels, 24 percent higher than the 2016 crop. Total barley state acreage harvested is forecast at 19,000 acres, up 4,000 acres from the 15,000 acres harvested last year.
The average 2017 Arizona barley yield is forecast at 125.0 bushels per acre, or 3.0 bushels per acre less than last year. As of July 2, Arizona barley growers had harvested 87 percent of their barley crop, compared with 73 percent last year.
Oh, never mind… Looks like you can grow barley in Arizona, and lots of it. They expanded planting into some areas that had not been in production before, so bu/acre went down, but the total crop went up a lot. Bu/acre 28% higher than wheat too.
So I guess we can worry about the beer when ALL of the USA & Canada are hotter and drier than Arizona… Call me when that happens… /sarc;
