Climate Change Threatens the World's Coffee Supply: A Brewing Crisis
The very regions that nurture our beloved coffee beans are now facing a dire threat due to global warming. This is a wake-up call for coffee lovers and farmers alike! But how did we get here?
In Ethiopia, the cradle of coffee, the livelihoods of over 4 million households are at stake. Imagine a world where this iconic beverage becomes a rare luxury! The country's coffee farmers are already witnessing the devastating effects of extreme heat. Dejene Dadi, a representative of a local cooperative, confirms the alarming situation.
Here's the shocking revelation: an analysis indicates that the primary coffee-growing regions are becoming inhospitable due to rising temperatures. The top five coffee-producing countries, which account for a staggering 75% of global supply, are experiencing an average of 57 extra days of heat that damages coffee plants each year. This is a direct consequence of the ongoing climate crisis.
Coffee beans thrive in a specific region called the 'bean belt', requiring precise temperature and rainfall conditions. The delicate arabica variety, in particular, struggles to survive temperatures above 30°C.
With approximately 2 billion cups of coffee consumed daily, the industry is feeling the heat. Prices of arabica and robusta beans skyrocketed between 2023 and 2025, reaching unprecedented levels in February 2025. Climate Central's analysis reveals that coffee-growing regions experienced numerous days above the critical 30°C threshold from 2021 to 2025, compared to a hypothetical world without carbon emissions.
El Salvador, a major coffee producer, faced the harshest impact with 99 additional days of coffee-damaging heat. Brazil, the global leader in coffee production, had 70 extra days above 30°C, while Ethiopia, contributing 6.4% of the world's coffee, endured 34 such days.
And this is the part most people miss: the sensitivity of Ethiopian arabica beans to sunlight. Without adequate shade, coffee trees suffer, producing fewer beans and becoming more susceptible to diseases. Local cooperatives are taking action, promoting energy-efficient cookstoves to preserve wooded areas that provide natural shade for coffee plants.
But here's where it gets controversial: smallholder farmers, who produce the majority of coffee, receive a mere fraction of the funds required to adapt to climate change. In 2021, they received only 0.36% of the necessary adaptation funds, according to advocates. This raises the question: are governments doing enough to support these farmers and secure our coffee supply?
The future of coffee hangs in the balance, and the clock is ticking. As Dadi emphasizes, without immediate action on climate change, the coffee industry's fate remains uncertain. Will we find a way to preserve this beloved beverage, or will climate change brew a bitter end?
