A recent study shows that extreme heat is already taking a toll on dairy farms in the Midwest and Eastern U.S., and the problem is expected to get worse by 2050. The research found that:
- Small farms and high-producing cows (those in peak lactation) are hit hardest by heat stress.
- Milk production drops due to heat stress, leading to an estimated 1% annual yield loss from 2012–2016.
- By 2050, losses could increase by 30% due to rising global temperatures.
- Heat stress not only lowers milk quantity but also reduces milk quality, which can impact farm income and nutrition.
Why This Matters
Dairy cows struggle in high heat and humidity, eating less and producing less milk. This has economic consequences for farmers and affects the availability of dairy products worldwide. The study also found that small farms face bigger challenges adapting to heat stress than large-scale dairy operations, which could lead to more small farms closing in the future.
What Can Be Done?
The study suggests that climate-smart farming practices—such as better cooling systems, improved farm management, and financial support for small farms—could help dairy producers adapt. With extreme heat events expected to become more common, taking action now is crucial for the future of the dairy industry.
