Drinking beer may become more expensive in the future because of climate change.<br />U.S. and Chinese researchers have found that climatic changes like heat waves and droughts will cause a fall in barley production, the main ingredient of beer, eventually leading to a rise in beer prices.<br />The team forecasts that by 2100, world barley production will decrease by as much as seventeen percent and the average beer price will double. This will result in a roughly sixteen percent decrease in beer consumption.<br />Researchers say Iceland will be the most affected where beer prices could jump by over three hundred percent by the end of the century. <br />
