Climate change adversely impacting world's coffee supply, new analysis finds

New Delhi, Climate change is adversely impacting the world's major coffee-growing regions with high temperatures reducing the harvests and contributing to higher prices of the popular beverage, according to a new report.

Coffee is one of the most sought-after non-alcoholic beverages in the world, with an estimated 2.2 billion cups consumed every day. In the United States alone, at least two-thirds of adults drink coffee daily.

According to an analysis by Climate Central, a not-for-profit group of scientists and communicators who research and report the facts about the changing climate and how it affects people's lives, the world's coffee supply is under growing pressure and climate change is playing a significant role.

Climate Central analysed temperatures from 2021 to 2025 and compared them to a hypothetical world without carbon pollution using the climate shift index. The analysis calculated the additional number of days per year that climate change pushed temperatures above the coffee-harming threshold of 30 degrees Celsius across the major coffee-producing countries.

When temperatures rise above this threshold, coffee plants experience heat stress that can reduce yield, affect bean quality and inc .
