Farmers benefit from cooling systems, which typically pay off in under two years. However, poorer farms may struggle to afford them, creating inequality in food production.
The researchers emphasize that beyond physical cooling, improving cow welfare is key. Reducing stress from confinement and calf separation helps cows withstand heat better.
As co-author Ram Fishman noted, “the severe impacts observed [in Israel] might be even more pronounced in less equipped regions.”
This research is one of the first to link real-time weather data with milk losses, offering a clearer picture of climate change’s effects on animals.
The study urges global investment in climate-smart agriculture, including breeding for heat tolerance and better policy support. Without action, the future of dairy farming—and a cold glass of milk—could be at risk.
