Cattle Welfare and Heat Stress Climate

Climate change is increasing the frequency and severity of heat stress events for cattle, requiring adaptation of farming systems.

Key Facts

Global average temperatures have increased by over 1 degree Celsius since pre-industrial levels
Dairy cattle heat stress begins at approximately 22-24 degrees Celsius temperature-humidity index
Projected climate scenarios suggest significant increases in heat stress days across European and North American dairy regions
Shade provision, sprinklers, and ventilation systems reduce heat load for housed cattle
Pasture-based systems increasingly require heat management infrastructure as temperatures rise

Welfare Considerations

Heat stress in cattle is a welfare problem that is becoming more severe and frequent as climate change accelerates. Adaptation through infrastructure investment, breed selection, and management change is essential to prevent increasing suffering in livestock populations.

What You Can Do

Support farms investing in heat stress adaptation infrastructure
Advocate for heat stress management standards in welfare certification
Choose dairy and beef from farms demonstrating proactive climate adaptation
