 Rising seas and severe storms are the most talked-about threats of climate change, but here's another, no more coffee. Because rising temperatures may cripple wild populations of / coffee, the most cultivated species in the world. So says a study in the journal PLoS ONE.


   
  Researchers used climate models to forecast the effects of warming on / coffee trees in Ethiopia, their native range. Under the best case of scenario 1, meaning fewer emissions 2 and less warming, only a third of today's range would still be suitable for coffee by 2080. And the worst case, wild / could be nearly wiped out in the region. 
   
  That's because coffee trees are sensitive to temperature, the researchers say, and they may not be able to colonize 3 new areas fast enough to beat climate change. That’s assuming no direct human impact, like clearing land for grazing, which is already a problem there. 
   
  Of course, the coffee in your cup doesn't come from wild trees, but wild coffee forests have a much bigger gene 4 pool than cultivated crops, meaning more resistence to disease, pest, and drought. Preserving that diversity might just be grounds to act on climate change.
