The document discusses the results of a study on the impact of climate change on coffee production. Researchers found that suitable land for coffee production could decline by up to 50% by 2050 due to rising temperatures and changing rain patterns associated with climate change. Arabica coffee was found to be especially threatened, as its growing regions may shrink by nearly 80% this century according to the study's climate models. The findings suggest that climate change could significantly impact global coffee supply and quality in coming decades if greenhouse gas emissions are not reduced.
