There was a “study” recently released proclaiming the end of beer … or at least a huge hike in beer prices coupled with a drop in availability due to climate change. Tim Worstall explains why the report is — at best — misleading:

You’ll have seen the various reports over the past few days that climate change is going to do terrible damage to the beer industry. The mechanism is that drought and heat will reduce the barley yield, this will then reduce the amount of beer that can be made. What follows is the explanation from the actual researchers of what they’ve done. It is, to put it mildly, nonsense. For their assumptions are wrong. Let us say that climate change does reduce barley yields on those lands currently planted to it. But we do know that as this happens then other, more polar, regions open up to being suitable for the growing of barley. So the initial worry is just untrue.
They then go on to insist that we’ll feed the cows on the barley that’s left rather than make beer from it. Thus the shortfall in beer is greater than that in barley. Nonsense upon stilts. Humans don’t work that way. We started this agriculture thing because we wanted the beer after all. Feeding the animals came later – and often enough the cows are fed on the barley after we’ve made the beer from it anyway. We’d put our minimal supply into booze not beasts.
Finally, they tells us that Irish beer prices would double. No, really, given the level of taxes there upon the stuff it’s really not true that even their 30% reduction in barley supply is going to double the price.
