"This study echoes two others highlighted on Science.org in 2019, which hypothesized that at least 60% of all wild coffee species are threatened with extinction, potentially within the next decade," "Coffee proved to be most vulnerable to climate change with negative impacts dominating all growing regions, primarily due to increasing temperatures." " in August, Bloomberg reported that Arabica farmers in Brazil, which represents the world's top exporter, are yet again seeing massive losses in its coffee crop, which "already had setbacks due to freakish weather, bringing lower yields that threaten to extend a global supply crunch."
