Calculating the long-term costs isn’t straightforward - it can be difficult to separate single, freak events from broader trends - but looking at coffee yields in Tanzania since the 1960s, one team has found that the crops fell from a high of 500kg per hectare to just over 300kg today. Importantly, the drop seems to closely follow a temperature rise of about 0.3C per decade, and an associated reduction in rainfall.

    All of which paints a bleak picture for the future. Using the latest figures for climate change across the globe, Bunn’s calculations predict that the land suited to farming Arabica could drop by as much as 50% by 2050. Classic coffee-producing regions, such as Vietnam, India and most of Central America, will be hit particularly hard.



War:

Of all the things climate change could affect in our daily lives this will be the one that spurs people to action above all the other things.
