"According to an analysis by the independent research group Climate Central, 25 countries that produce almost all the world's coffee experienced 47 days more of coffee-harming heat on average between 2021 and 2025. The five countries that account for 75% of global coffee production Brazil, Vietnam, Ethiopia and Indonesia saw 57 more days of such temperatures in the same period."
"Temperatures above 30 C (86 F) are "extremely harmful" to arabica coffee plants the dominant variety making up some 60-70% of global production and "suboptimal" for the robusta variety that accounts for most of the rest, Climate Central said. For its analysis, Climate Central estimated how many days each year would have stayed below 30C in a world without global warming but exceeded that level in reality."
"What did Climate Central say about effects on coffee production? Kristina Dahl, Climate Central's vice president for science, said climate change posed a serious threat to coffee production. "Climate change is coming for our coffee," she said. "Nearly every major coffee-producing country is now experiencing more days of extreme heat that can harm coffee plants, reduce yields and affect quality," she added in a statement."
Human-caused warming has increased the number of hot days in major coffee-growing regions, reducing yields and pushing prices higher. Twenty-five coffee-producing countries experienced an average of 47 additional days of coffee-harming heat annually between 2021 and 2025. The five countries supplying roughly 75% of global coffee saw 57 more such days in the same period. Temperatures above 30 C (86 F) are extremely harmful to arabica and suboptimal for robusta. The estimate compared actual days above 30C to the number that would have stayed below 30C in a world without global warming. Increased heat can damage plants, lower quality and threaten future production.
