The coffee industry worldwide is concerned about the susceptibility of its crops to climate change for good reason. Coffee plants in general are very sensitive to heat and arabica coffee plants, which produce the beans for pretty much every cup of coffee sold in cafes, are particularly so. Minor changes in temperature, water supply and humidity have the potential to generate huge losses. To make matters worse, coffee diseases are expected to flourish as temperatures climb. Indeed, new work reveals that between 35% and 75% of the land currently used for Arabica coffee plantations will become economically unusable in the decades ahead. This is bad, but the industry is not without options. Read all about how to save your morning espresso in my article in The Economist here.
