As far as I know, the only coffee affected by climate change is the original wild Arabica strain that grows in the Ethiopian highlands, which is needed to periodically crossbreed with the commercial strains. Climate change is inevitable, the only real question is how much change can we expect in the near future. I'm by no means an alarmist, human activity simply doesn't compare to the awesome forces of nature. That said, heavily cultivated crops like coffee and bananas have nearly failed before from soil fungus and plant diseases. Having a third viable strain is good news. ***** https://www.atlasobscura.com/articles/where-is-coffee-from >Arabica coffee is self-pollinating, pollinating itself about 95 percent of the time, and it spread around the globe from a literal handful of seeds. As a result, cultivated Arabica is genetically weak and unable to withstand or adapt to the diseases and changing climate that are battering production. Coffee leaf rust, which has decimated coffee-growing regions before, wiping out the entire industry of Ceylon (now Sri Lanka) in the late-19th century, has sent Latin America’s industry into a tailspin.
