A Culinary Silver Lining of Climate Change: More Truffles
The cultivation potential of a popular truffle species will increase in central Europe by 2050, global climate models predict.
A truffle might not be much to look at, but chefs worldwide revere these subterranean-dwelling fungi for their intense, earthy flavors. Now, scientists have looked to the future of truffle cultivation in Europe by modeling three different climate-warming scenarios. They found that climate change will substantially increase the cultivation potential of one species of truffle commonly used in cooking. Given that truffle farming can be lucrative, it appears that climate change has a culinary silver lining, at least for the niche world of truffles, the researchers concluded.
An Expensive Fungus
Tomáš Čejka, a climate change scientist at the Global Change Research Institute of the Czech Academy of Sciences in Brno, and his colleagues focused on two species of truffles: Tuber aestivum (Burgundy truffle) and Tuber melanosporum (Périgord truffle). These truffles are among the most commonly used in kitchens and cost hundreds of dollars per kilogram. (They’re not quite as renowned as Tuber magnatum, however, a species of white truffle that commands ever higher prices.)....
