Description: Rising global temperatures will slash milk production and could cut yields by 4% daily by 2050, threatening food security and dairy livelihoods.

A groundbreaking 12-year study reveals that extreme heat will cut dairy cows’ milk production by up to 10%, with even a single hour above 26°C wet-bulb temperature triggering a measurable drop in yield.
The impact lingers for days, and by 2050, global milk output could fall by 4% daily due to rising heat stress.
South Asia, expected to drive most of the world’s dairy growth, faces the greatest risk.
Current cooling systems—like fans and sprinklers—only reduce 40% of heat-related losses.
