Workers across California are grappling with yet another climate change-induced threat: a rapidly spreading fungus that can land its unsuspecting victims with prolonged flu-like symptoms, or far worse. The culprit is a soil-dwelling organism called coccidioides, which is now spreading the disease coccidioidomycosis — known as “Valley fever” — farther and farther north of its Southwest origins. Rather than spreading from person to person, Valley fever results from the direct inhalation of fungal spores — spores climate change is now allowing to flourish in new places.
