As most people who know me already know, I use coffee to teach geography, and geography to teach coffee. Murray Carpenter's report from the World Coffee Conference in Guatemala (sadly, I was not there), does exactly what I strive for: it uses coffee as a lesson on climate change.
When I visit coffee farms in Nicaragua, I am sometimes asked, "What are you doing about climate change?" As Carpenter's story points out, the mountains are pointy, so going up is not necessarily an option. And coffee requires a great deal of specialized knowledge, hard work, and patience. So even if a changing climate results in suitable microclimates in new locations, good coffee will not automatically follow.
