Extreme heatwaves may cause global decline in dairy production, scientists warn

Israel-based study finds that by 2050 average daily milk production could be reduced by 4% as a result of worsening heat stress

Dairy production will be threatened by the increasing frequency and intensity of heatwaves, a study has found.

Drawing on records from more than 130,000 cows over a period of 12 years, the researchers report that extreme heat reduces dairy cows' ability to produce milk by 10%.
