Coffee is notorious for being picky about its climate conditions, with the most popular varieties only growing at specific altitudes in the tropics. That alone makes coffee susceptible to climate change, but the plants are also fussy about their pollinators, which will also be affected by the changing climate. A new analysis suggests that climate change on its own could cause coffee producing areas in the Americas to drop production by roughly 80 percent.
