There's Not a Lot of Coffee Anymore ?

Arabica and Robusta coffees grow at optimal temperatures of between 18 and 22 and 22 and 28 degrees Centigrade, respectively. The effects of temperature, rainfall and humidity, on crop productivity in the top 12 coffee-producing areas, were assessed between 1980 and 2020. Rising temperatures seemed to have most direct impact in reducing coffee yields (https://www.theguardian.com/environment/2023/mar/09/rising-temperatures-in-tropics-to-lead-to-lower-coffee-yields-and-higher-prices-study-suggests). The 12 coffee producing areas are changing from being cool and wet, to being hot and dry. This is clearly a consequence of climate change. In deed, it's estimated that the land suitable for coffee growing will halve by 2050. Reducing the area for growing and declining yields, of course, markedly increase the cost of this beverage.
