Extreme heat threatens Italy's $4.7 billion cheese economy

Extreme heat is threatening Italy's $4.7 billion Parmigiano Reggiano cheese industry. Heat has cut cows' milk production by up to 10%, while drought has reduced grass and hay supplies. Farmers are installing fans and misting systems, raising costs. Cheese warehouses are using more energy to maintain temperatures, making production and storage costlier, putting pressure on producers and farmers.
