Coffee varieties have adapted to specific climate zones, a temperature rise of even half a degree can make a big difference. A long-term increase in the number of extreme and unseasonal rainfall events has contributed to lower crop yields that are threatening the livelihood of coffee growers. For example, between 2002 and 2011, Indian coffee production declined by nearly 30 percent.Additionally, warming has expanded the habitat and thus the range and damage of the coffee berry borer, a grazing predator of coffee plants. This pest is placing additional stresses on all coffee crops, as is coffee rust, a devastating fungus that previously did not survive the cool mountain weather. Costa Rica, India, and Ethiopia, three of the top fifteen coffee-producing nations in the world, have all seen a dramatic decline in yields.
There is no single solution to climate change, but there are technologies and approaches available now that can reduce global warming emissions by at least 80 percent by mid-century.
Don't get all worked up. Have another cup of coffee.
