Climate change is seriously impacting milk production and dairy quality nationwide, experts warn. Researchers at Cornell University assessed six and a half million dairy cows collectively.

Analysis links local weather patterns directly to regional milk yield and compositional levels.

Findings reveal summer heat and humidity reduce both milk quantity and its nutritional value. Decreased milk quality persists throughout milder seasons, with losses accumulating gradually over time.

Annual economic losses approach one billion four hundred fifty million euros for dairy industry. Ventilation and cooling in farms recommended, but regional data gaps remain for Europe.
