Availability of coffee in a warming world

Most of the coffee-plants are grown in Africa, South America, south-eastern Asia and Indonesia. Despite that, more coffee is drunk in Finland than in any other country, when consumption is compared to the number of the population. Finns consume almost 10 kg of roasted coffee per person every year.

Therefore it was interesting to note that global warming may soon make it impractical for many plantations to grow the world’s most popular coffee bean, Coffea arabica. As a solution, coffee growers in Africa have seriously turned their view to a long-forgotten variety, C. liberica.

This plant was widely grown in the 1870´s, but due to its fruits being large and hard to process, the bean lost its popularity at the turn of the 20th century. Due to problems with C. arabica, Ugandan farmers have recently started to ramp up cultivation of a subspecies "excelsa" of C. liberica , which is resistant to wilt and other diseases. 

It produces excellent coffee and does not need chilly high altitudes to thrive. Therefore it seems that coffee cups can be kept full even if the planet warms as predicted. I believe this is a welcome news for the caffeine-addicts throughout the world - and especially valuated in Finland inhabited by the record holders.
