Experts are saying global warming may cause failed barley crops - one of the main ingredients in beer.

Jim Salinger, a climate scientist, is quoted in the Daily Star: "It will mean either there will be pubs without beer or the cost of beer will go up." He warned that the whole world's beer supply was at risk, and that it could hit within 30 years.

He said: “It’s already happening and will get worse."
